[android-developers] Animation

[HVT]

Hello All,

I'm facing a problem while clicking the objects while they animate.
Please help me identify the click on the objects while they are
animating.

My requirement is to randomly move a ball around the screen and the
user should be able to click this ball any time.

Also this ball changes colours. For this is i have 3 different images
of different colours and I want to create a frame by frame animation
between them while they are animating.

This makes it 2 animations at a time. a frame-by-frame animated image/
object has to animated may be a /translate animation and this should
be click able.

Please help me fix this. I have stuck on this part for almost over a
month now.

Thanks,
HVT

[android-developers] Animation Issue

[Alowishus]

Hey Gang,

Is there a way to pre-load frame by frame animations? It seems to me
that when using frame by frame animations the first run through of the
app cause some stuttering for the end users as  the frame by frame
images are fetched from the application instead of running through
normally. The 2nd run through everything runs smooth, but the 1st run
through causes some stuttering as the images are being retrieved.

[android-developers] Animation Styles

[skink]

hi,

i tried to use my popupWindow with some enter/exit animations - it has
setAnimationStyle() method for that purpose.

after some time i realized i cannot use my own custom animation styles
which is ok but a bit limiting. so i tried system ones:
R.style.Animation_Toast works ok, but R.style.Animation_Dialog
doesn't.

looking at xml definition files i found that Toast animation uses
simple alpha animation and Dialog animation is a set of alpha combined
wit scale animation.

is it a problem for WindowManager to deal with complex animations?

skink

[android-developers] Animation Problem

[HVT]

Hello All,

I'm new to Android and trying to develop an app that has loads of
animation.
Its a small game.

Currently i have a object (image) moving around the canvas. I used
animation to animate it around the screen.

But the problem here is i dont have the X&Y coordinates of that object
while its animating.
I want to get the coordinates of the bitmap whenever i want during the
animation.

I think if there was some way where i can read the presentation layer
probably i could get the cordinates of the object.

Please help me guys i'm stuck here now for like a week.


My another problem is with rotate animation, i some how dont seem to
understand its functionality.
I have played with it for a couple of days but no luck, i'm still new
to it and dont get anything.

The object makes big arcs even if the  x,y values are  0,0 and the
object jumps around when i try to give it random values.

Any help would be highly appreciated.


Thanks in advance.

[android-developers] Animation loop

[arnouf]

Hi all,

I created an animation in an xml file.
I apply it on a textview like this :
Animation anim = AnimationUtils.loadAnimation(this,
R.anim.exit_about);
anim.setRepeatMode(Animation.RESTART);
anim.setRepeatCount(Animation.INFINITE);
v.findViewById(R.id.global_about).startAnimation(anim); // v is my
view

This runs once even if I set a repeat count.

Any idea ?

[android-developers] Animation behavior

[gymshoe]

I want to perform animations within a view.  However, the behavior of
the animations does not seem consistent depending on the sequence, and
I don't understand why.  This example performs a simple fade out of
the image:
XML:
http://schemas.android.com/apk/res/android";
android:interpolator="@android:anim/accelerate_interpolator">



However, if I have change the XML, so that the animation should fade
back in, nothing happens. The screen blanks out (not fades out) and
then reappears after the animation is over.
XML:
http://schemas.android.com/apk/res/android";
android:interpolator="@android:anim/accelerate_interpolator">



NOTE: if I run just the "fade-in" sequence alone (the second half),
then it also works appropriately.

What am I missing?  Thanks for any assistance.

[android-developers] Animation doubt

[Sebastián Treu]

Hi all,

I want to slide down a RelativeLayout filled with information. I have
written this animation:


http://schemas.android.com/apk/res/android";
android:fromYDelta="0"
android:toYDelta="87%"
android:duration="350"
android:fillAfter="true"
/>

The animation parameters are ok. But, when fillAfter is true, the
RelativeLayout measures are wrong. In fact, the getTop() is still the
same as before. And, if I set a listener to call
layout(int,int,int.int) onAnimationEnd(), the layout dissapears until
I click it. I call layout() this way in onAnimationEnd() method:

 if (animations[MOVE_DOWN] == animation) {
textBox.layout(left, top, right, bottom);
textBox.postInvalidate(left, top, right, bottom);  //just for
testing if this redraws the layout


And, if I set the fillAfter to false, and onAnimationEnd() I call the
layout() method without the invalidate method, when the view gets
updated (it's connected to a onItemClickListener from a Gallery) with
information, it will be redraw "expanded".

Anyone can give me a tip how to create such effects? I set a
background layout as those folders tabs. I want to slide it down and
up, upon user touch events. I managed to do that. The animation is
like I want, but data it's not consistent. How to make the layout data
consistent with the animation data? I tried out with the listener
calling the layout() method, but the RelativeLayout dissapears.

Any help?

Regards,

PS: I can make a video to show how the animation is missbehaving.

Hi Abhijeet, here is your solution.

Use addFrame() method like this:

 animation.addFrame(BitmapDrawable.createFromPath ("sdcard/image1.png"),
250);


I hope, you got it.

[android-developers] Animation problem

[iced]

Hello,
I'm new here and I don't know if this is the right place for my
problem. Please excuse me if it's wrong.
I want to create a scale animation where a view grows a bit from it's
original size and then shrinks to it's old size.
My XML file:

http://schemas.android.com/apk/res/android";>



When I start this animation the view object grows directly by the
factor 1.2. Then the animation starts and the view grows and shrinks
like I want it. After that there is another jump to the original size
of the view. So there are two jumps, which I don't want and I don't
know how to solve this problem.
Please could you help me.
Thank you

[android-developers] Animation Between Tabs

[Chatur]

Hi All,

I wish to add make-in/make/out animation from AnimationUtils between
tabs as i scroll(left/right) through them.Each of the tabs represent
an activity having different layout files as their content view.The
tab that i scroll to  should slide into the screen through makein and
the previous tab must slide out of the screen through makeout.


I tried this using simple tabs that have a common layout file as
their
content view,and invoked startanimation on the individual views that
i
wish to animate.I was successful in doing so.but now,since there are
going to be multiple layout files,I cannot go about using this
approach.I have an idea about it.I guess LayoutAnimationController
has
to be used to enable the same.


Could anyone help me to get started with this problem?

[android-developers] Animation seems slow

[Rohit Mordani]

I have a Grid View and it has 6 jpeg images. I am applying a scale and
alpha animation to that grid and then at the end of the animation i
set the visibility of that view to invisible. The animation seems
slow. I tried to use an AccelerateInterpolator but that doesnt seem to
help. Is there a way to speed up the animation? Here is what my
animation looks like (testanim.xml)


http://schemas.android.com/apk/res/android";>







I load this animation in java as follows

GridView gv = (GridView) findViewById(R.id.grid);
Animation a =  AnimationUtils.loadAnimation(this, R.anim.testanim);
a.setInterpolator(new LinearInterpolator());
gv.startAnimation(a);
gv.setVisibility(View.INVISIBLE);


any ideas what I need to do to speed up the animation?

[android-developers] Animation is slow?

[Mark Wyszomierski]

Hi,

I'm trying to perform a simple animation, but it seems quite choppy.
This is it:

  Animation anim = new TranslateAnimation(0,0,-50,0);
  anim.setDuration(500);
  anim.setInterpolator(new LinearInterpolator());
  myLinearLayout.setAnimation(anim);

the animation does what it's supposed to do, just very choppy - is
there any reason why it's so slow? The linear layout I'm applying it
to is pretty simple, just has a few children,

Thanks

[android-developers] Animation on widgets

[Daniel]

In my app I have a EditText widget. Since I need that EditText at
different positions within the activity I perform some animations to
move it around. I don't want to set the position without an animation.
The animation also has the fillAfter attribute set to true so the
EditText widget stays at the new position after the animation is done.
Up to this point everything works perfectly. But now if I scroll
through my app the selection of the EditText is always drawn at the
original position of the EditText. Is there any possibility to move
around the EditText with an animation and have it behave correctly
also when it is selected (has the orange border)?

Thanks,
Daniel

http://code.google.com/android/samples/ApiDemos/src/com/google/android/samples/animation/Transition3d.html
the resulte is nice, but it's a bit complicated and it didn't work in
my case. Does anyone as an idea ?

[android-developers] Animation for Bitmap

[Sebastian]

Hi list

i'm developing a small game and for that purpose i extended
SurfaceView and override the onDraw() method to draw Bitmap objects on
the x/y coordinates i like:

public void onDraw(Canvas canvas) {

fCanvas = canvas;

fCanvas.drawColor(Color.rgb(0, 0, 255));

if (!pausing) {
GameObject[][] gameObjs = level.getLevel();

for (int x = 0; x < gameObjs.length; x++) {
for (int y = 0; y < gameObjs.length; y++) {
if (gameObjs[x][y] != null) {
gameObjs[x][y].drawObject();
}
}
}
}

here the drawObject() method

getCanvas().drawBitmap(getBitmapCache().get(bitmapRef), x, y, null);

this works great, but now i like to rotate or fade out the bitmap im
drawing. for this purpose i create an animation but the problem is,
there is no method Bitmap.startAnimation() or something like that. how
can i do this nevertheless? any hints??

thanks

[android-developers] Animation and ListView

[Sebastian Müller]

Hi

Im using a listview to display some self defined objects. this works great.
then i wrote an animation to smoothly slide down the list:

 *Code:*
public static void downFromTopAnimation(ViewGroup panel, Context ctx) {

  AnimationSet set = new AnimationSet(true);

  Animation animation = new AlphaAnimation(0.0f, 1.0f);
  animation.setDuration(100);
  set.addAnimation(animation);

  animation = new TranslateAnimation(
  Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF, 0.0f,
  Animation.RELATIVE_TO_SELF, -1.0f, Animation.RELATIVE_TO_SELF, 0.0f
  );
  animation.setDuration(500);
  set.addAnimation(animation);

  LayoutAnimationController controller =
  new LayoutAnimationController(set, 0.25f);
  panel.setLayoutAnimation(controller);

}


i call this with downFromTopAnimation(listview, context); This works really
great, but if a expand the list with more objects, the whole list is slide
down with the animation but i'd like to change it so that only the new items
slide down smoothly.

has anybody any hint how to do this??

thanks

[android-developers] animation fillAfter question

[Susan]

Animation fill* attributes confuse me. The document is simple. For
example:

layout xml:




anim xml:


http://schemas.android.com/apk/res/android";>





I think text will freeze after animation end. But it returned to (0,0)
again. Why? Is the second translate's fillAfter="true" invalid?

[android-developers] Animation won't repeat

[John Lussmyer]

Now, I have the problem that my animation won't repeat.
It plays just once.

My onCreate does this:

testAnimation = AnimationUtils.loadAnimation(getBaseContext(),
R.anim.testanim);
testAnimation.setAnimationListener(mAnimationListener);
testAnimation.setDuration(3000);
testAnimation.setRepeatCount(10);
testAnimation.setRepeatMode(Animation.RESTART);

and my onClick does this:
if (running) { // Currently running, stop it

button.setText(R.string.Button01);
testShape.clearAnimation();
} else { // Currently stopped, start it

button.setText(R.string.BtnStop);
testShape.startAnimation(testAnimation);
}

The animation plays exactly once, and the listeners onAnimationStart() is
called exactly once.

Re: [android-developers] Animation problem

You may want to set the setFillBefore and/or setFillAfter values.  (one of
them defaults to true, the other to false.)

[android-developers] Animation in webview

If anyone can help me with this I will be very happy. I have an

the Google tutorial to overide all the other links that I want to open
with webview also. I have create an anim in res and a slide_right xml
and so far so good. I call the effect in my main java activity but it
only applies to the first page. The thing that I want is the effect to
apply in every page that links loads in webview.

[android-developers] "animation-less" android menus

[Gilles TALIS]

I am planning to use android on a device with slow refresh rate
display.
I was wondering whether it was possible to bring up the apps menu
without sliding the apps menu pull-tab, just with a long-press menu
button for instance.

Ideally, this long press action would directly show the apps menu
without the sliding animation.

Is this possible?

[android-developers] Animation between 2 activities?

[Marc Reichelt]

Hi there!

I program on an application where different views are arranged
horizontally, each view of screen size. The user should be able to
switch between these views using his finger. I first used the
ViewFlipper, which was great for simple layouts, but which is *way*
too slow if the layouts of the views are more complex, because all
Views are drawn.

A much better method would be to place one layout per activity and
switch between these activities using the slide in / slide out
animations.
Is something in this direction possible with Android right now? Any
recommendations or best practices?


Regards & great thanks in advance

[android-developers] Animation of a View

[Eddified]

I understand that animating a View using startAnimation() with a
TranslateAnimation object really just applies a transform on the
canvas that is being drawn on. In my case, the problems with this are:
a) sometimes I need to call bringChildToFront() (for a different View)
on the ViewGroup during the animation, which messes up the animation
because it triggers a requestLayout on all children, which in turn re-
lays out the child being animated... which messes up the continuity of
the animation. Perhaps causing a layout on the child being animated
isn't supposed to mess up animations, but it seems to be in my case.
b) after the animation (using an AnimationListener), I need to re-
layout the child to the new location, which is fine in concept, but
again messes up the animation because for some reason the actual
drawing of the last frame of the animation hasn't finished by the time
onAnimationEnd() is called. This causes the animation to go awry at
the very end. What's happening in my case is if I layout the animated
view to its new location in onAnimationEnd, the last step of the
animation is being applied to the new layout, so the view looks like
it is jumping around the screen. I tried a handler with no delay, and
that didn't work either. Using a handler with a delayed message to
accomplish the new layout works but is such a hack that I worry it may
not work correctly on another piece of hardware.

I could accomplish the animation by taking out the TranslateAnimation
and instead do a manual animation, and in the manual one, change the
layout of the view gradually (instead of transforming the matrix of
the canvas) but that's a lot of work and error-prone.

Any ideas? Are there tools I can use (besides manual application of
Handler.sendMessageDelayed()) to accomplish an animation that actually
re-lays out the view on each iteration instead of altering the canvas
matrix?

[android-developers] Animation Maker and Viewer ?

[ginnie]

Hey..

I needed some insight on this issue :
( sorry if it sounds trivial :)  )

Is there a way to make and/or run an animation on android ?
(animations as in flash / powerpoint / applet or any thing else.. )

does webview support downloading and viewing any animation?

i intend to use some kind of an "animation maker and viewer tool"
running on android (some code that allows user to create animations
they may share with other android users who may view this animation)

for an application I wish to code..

Is there any thing like this out there ?

Thanks ..

[android-developers] Animation across the layouts

[BouHu]

Hello.

I've met a problem with animation when tried to make a View to perform
the animation which should cross 2 layouts, e.g. make a translate
animation so a view could move down to the TableRow below. This trick
works fine when i try to move a view within a single TableRow but not
when i try to move it up or down. I've also discovered that if i
create a single RelativeLayout and apply the same animation there, it
works fine, but i can't arrange all the components i need on the
screen.

Could anybody please provide me any hints about it?

Best regards.

[android-developers] animation for growing listview

[daniel.benedykt]

Hi

I want to do an animation so when a user presses a button a listview
changes its height (grows).
I know how to change the height of the listview to make it bigger, but
that its not 'animated'.

How can I make an animation that makes the listview grows?

Thanks

[android-developers] animation between two activities

[tstanly]

hi all,

I design a rotate animation when activity 1 ends, and then start
activity 2.
so my code is:
===when activity 1 ends function===

rotate_animation();  //first call up the animation

Intent i=new Intent();
i.setClass(activity1.this,activity2.class);
startActivity(i);

===
but this code will not saw the animation totally,
that's means, the animation will pop up a second then soon activity2
start!
but I need the animation play over, then the activity 2 start.


so how I do for that requestion?
I almost use the thread&handler to do, but it wasn't work.

thanks!

[android-developers] Animation of View size

[hoha]

Hi all.

I've noticed that animation framework is based on matrix
transformations (with additions for alpha). Did I get it right that
it's impossible to animate an arbitrary property (e.g size) of my view
with android.animation.* tools? If so, can you please give me some
hints how size animations can be implemented?

My task is to resize some custom view smoothly (redrawing/laying out
it on every 'frame').

Thanks!

[android-developers] Animation using several drawables

[Michael]

Hi,

I am a little stuck with exactly what approach to take with an
animation problem.

I have several bitmap resource drawables, a face with no eyes or
mouth, a mouth and eyes. I want to be able to build these drawables up
to make the face and then use tween animations on them to animated the
face. The size of the eyes and mouth drawables are only big enough to
contain the content and so need offsetting when overlayed on the
face.

I initially thought i could use a LayerListDrawable in an ImageView to
overlay the drawables with appropriate offsets and then animate each
drawable, but in this case all the the drawables are scaled up to the
size of the largest drawable.

I was also wondering if I could use a FrameLayout with several
ImageViews and somehow offset them to build the initial image and then
animate each ImageView, but I am not sure how I would do this.

I could use a custom View or a SurfaceView and do the animation
myself, but I would like to stick to using the stock components if at
all possible just to keep it simple.

Anyone got any ideas or done something similar?

Cheers,
Mike

[android-developers] Animation Is repeating...why?

[MikeMike]

I am trying to get my imageView animations to play serially.  But when
onAnimationEnd the original one somehow replays :


   private void drawCurrentGame()
{
final LinkedList animation_queue =
(LinkedList) current_game.clone();

ImageView working_view;

final AlphaAnimation anim = new AlphaAnimation(0.0f, 1.0f);
anim.setDuration(500);

anim.setAnimationListener(new Animation.AnimationListener() {
public void onAnimationStart(Animation a)
{

}
public void onAnimationRepeat(Animation a) {}
public void onAnimationEnd(Animation a)
{
ImaveView v = ((AlphaAnimation)a).getView();

if( animation_queue.isEmpty() ) return;
animation_queue.poll().startAnimation(anim);
}
});

 if( !animation_queue.isEmpty())
 {
 animation_queue.poll().startAnimation(anim);
 }
}


HElp please!

Using "this" instead of getBaseContext() made no difference.
listener onAnimationRepeat() is never called.
Very simple animation:

Re: [android-developers] Animation won't repeat

Try specifying the repeat (and maybe the right duration) in the XML
instead of in Java. That should not make a difference, but it is at
least worth a try.

Otherwise, I see nothing obviously wrong.

Re: [android-developers] Animation won't repeat

[John Lussmyer]

Now, that is interesting.
Moving the repeatCount and repeatMode settings to the XML made it mostly
work.
Setting the Duration in the Java does properly override the setting in the
XML.  Setting Count and Mode does not.

Also, the listeners onAnimationStart() is called exactly once.
OnAnimationRepeat() is never called - even though the animation is
repeating.

Re: [android-developers] Animation won't repeat

[John Lussmyer]

onAnimationEnd() is called exactly once - when I do the
testShape.clearAnimation() to stop it.

Re: [android-developers] animation between two activities

[Dianne Hackborn]

My suggestion would be -- generally don't do this.  Animations during
activity transitions are done by the window manager, on their windows.
 Prior to 2.0, these were turned off by default (though could be turned on
by the user), and as of 2.0 they are turned on by default.

Trying to create your own animation in your own view, is (a) inconsistent
with the standard Android UI, (b) not following the user's preference, and
(c) going to interact extremely poorly with the normal activity animations
when they are shown.

There can of course be exceptions to this, for example perhaps the next
activity is translucent in which case there is no animation on it normally
and an animation within the previous activity's UI would not conflict with
it.  But that kind of thing is going to be very, very rare.

Also as of 2.0 there are some new APIs to customize the actual activity
animation for a particular transition...  though again, I would highly
recommend not doing this except under extremely special circumstances, since
it makes your application inconsistent with whatever standard animations the
user sees.

And one other thought on animations: the animations that are shown during UI
transitions have a very strong impact on the user's perception on how they
are moving through the UI and where they are.  Replacing the standard ones
with gratuitous custom ones has a very high chance of harming the user
experience, because it tells the user "something really importantly
different happened here;" if what happened was actually a normal navigation
(such as between two activities), then this can end up being very misleading
and confusing.

[android-developers] Animation startOffset failing, 2.1 bug?

[Cardy]

Hi,

I've taken some animation xml straight from the android docs, and as
far as I can see, doesn't work on either my 2.1 update 1 emulator or
my 2.1 update 1 Galaxy S device.

Specifically, I'm trying to create an animation to pulsate a view
(i.e. make it smaller then larger in one animation)

This is the very simple markup:


http://schemas.android.com/apk/res/android";>








So what I'm trying to achieve is to reduce the view from its size to
half of it over a second, then to increase it back to its original
size over a second.

What actually happens is it snaps instantly to half of the views size
(even though fromX/YScale is at 1.0) and then performs the animation
and snaps back afterwards.

Can anyone else try this our quickly? If others see this behaviour
I'll submit it as a bug. I just can't believe something so basic could
be broken!?

Also, copying this animation under the "Tween Animation" heading on
this page http://developer.android.com/guide/topics/graphics/2d-graphics.html
word for word also doesn't animate as per the page says.

Anyone got any ideas?

Thanks!

Andy.

[android-developers] Animation overlay over camera preview

[Yamanoor Sai Ram]

I would like to create an animation over a camera preview. * *My camera

I have attached an example of the layout of my app. There are 9 rectangular
bars on the left hand side. I would like to display one rectangle after the
other to animate a status bar. I created a relative layout for the camera
preview overlay. I am not sure how should I go about doing it. Any
suggestions would be appreciated.

[android-developers] Animation stops timer (newbie alert!)

[CasaDelGato]

I'm starting to play with doing some simple animations.
I have one where I want a sound and animation to play every X seconds
after a button is pressed.
So I set it up like this:

private ScheduledThreadPoolExecutor threadRunner = new
ScheduledThreadPoolExecutor(
4);
private SoundPlayer mSoundPlayer = new SoundPlayer();
private ScheduledFuture playerFuture = null;


private OnClickListener mClickButton = new OnClickListener() {
public void onClick(View v) {
Button button = (Button) findViewById(R.id.Button01);
if (playerFuture != null) {
button.setText(R.string.Button01);
playerFuture.cancel(false);
playerFuture = null;
} else {
button.setText(R.string.BtnStop);
playerFuture = (ScheduledFuture)
threadRunner.scheduleAtFixedRate(mSoundPlayer,
0, 3000, TimeUnit.MILLISECONDS);
}
return;
}
};

private class SoundPlayer implements Runnable {
private MediaPlayer mPlayer;
private TextView testShape;
private Animation testAnimation;

public void run() {
if (mPlayer == null) {
mPlayer = MediaPlayer.create(getBaseContext(), 
R.raw.ding);
testShape = (TextView) 
findViewById(R.id.TextView02);
testAnimation = 
AnimationUtils.loadAnimation(getBaseContext(),
R.anim.testanim);
}
mPlayer.start();
testShape.startAnimation(testAnimation);
return;
}
}

The problem is that the call to "startAnimation" seems to stop the
timer.
The sequence of events is:

Press Button (starts timer)
Sound plays once
Press Button (to stop the timer)
Animation plays once
Press Button (starts timer)
Sound & Animation play once
Press Button (stops timer)
nothing happens
Press Button (starts timer)
Sound & Animation play once
...

If I remove the call to testShape.startAnimation(), the timer runs,
and the sound plays every 3 seconds until the button is pressed again.

I must be doing something wrong with the animation, but I haven't been
able to figure out what.

[android-developers] Animation with only one view

[Jeremy Cowgar]

Hello,

 I have a view that browses data with a large amount of numbers. When
going to the previous or next record if you're not really paying
attention it's possible to not detect that it actually moved because
many times the numbers are very similar. I have added a page counter
to the view (1/20, 2/20, ...) but even that is not the best solution,
I don't think.

I would like to do a slide out/in or some other type of animation when
chaning records as to provide a positive move but my problem is that
it is only one view. I am not changing views, just changing the data
with in the existing view. I have managed to make some terrible
transition animations but nothing is working as I would like. For
example, I slide the current view out then in the animation listener
when completed, I update the view and slide it in. It's not a nice
smooth transition and the screen is blank for a short period of time
between the two animations as one slides out, then blank, then one
slides in.

Can anyone point me in the right direction to make this type of
animation work correctly?

Thanks,

Jeremy

[android-developers] Animation Leaving Trail Using AnimatorSet

[Craig]

I am using the new honeycomb animation api and am having a problem with 
animated ImageView objects leaving a trail when animated.  The app downloads 
images via http, makes and ImageView and adds that to a list view (which is 
in a fragment) and animates each one with its own AnimatorSet (consisting of 
2 ObjectAnimator.ofFloat for the x/y coords).  Screenshot sample:  
http://imageshack.us/photo/my-images/824/trailm.png

10 images are displayed at a time, each being downloaded asynchronously, 
added to the view, and animated immediately.  The trail is usually only 
there for 1 or 2 of the 10 animated images, but it happens for about 95% of 
the times I test it.

If it helps, this is bring done on Android 3.0.1 on a Galaxy Tab 10.1 device 
(from Google IO).

I saw an old thread in this group, but the answer was that it was fixed in 
Donut:
http://groups.google.com/group/android-developers/browse_thread/thread/5481450f8b71a26c/e750730b9953d9a8?lnk=gst&q=animation+trail#e750730b9953d9a8

Given that this is the new animation system, is there a new, similar bug 
here?  Can anyone offer suggestions on how to fix this?

Thanks.

[android-developers] Animation not displaying in onBackPressed

[Stefan Alder]

I'm trying to slide a custom modal view off the screen with a
translation animation when the user presses the hardware back button.

I call the panel.setAnimation method within onBackPressed, but while
the method executes, the animation is not visible.  Only until I touch
the display does it redraw to the final state (with no animation).  I
tried running the animation method via runOnUIThread, but that made no
difference.   Any idea why the animation is not being displayed?

If I use a custom button on the screen to call the animation, it works properly.

Thanks

[android-developers] Animation not working as I want

[fhucho]

Hi,
I have a LinearLayout, with a text and a button, which I want to show
and hide (using translate animation) sometimes. As for now I show/hide
it by setVisibility() to View.GONE or View.VISIBLE. To set the
translate animation I do this:

myLinearLayout.setLayoutAnimation(new LayoutAnimationController
(myTranslateAnimation));

But when I call myLinearLayout.setVisibility(View.VISIBLE),
myLinearLayout shows imediately but without the text and the button.
The text then slides to the linearlayout and then the button does the
same. When I call setVisibility next time there is no animation at all.

[android-developers] Animation to be played in sequence

[j]

Hi,

I understand that to play a set of animation in parallel, one would

set of animations in sequence, one by one.

For example, I want the effect of fade in and then fade out in
sequence.

How do I do that?

[android-developers] Animation fillAfter(true) and click locations

[Loki117]

Evening all,

I had a quick questions around animations and what is going on. So I
have buttons in a vertical row down the side of the screen. Upon
clicking the last button the row animates and slides out at the top of
the screen. This works HOWEVER when the user clicks the same button
again (the only button still visible) nothing happens. It seems that
if I click where the button used to be the view reanimates. Does
anyone know why this happens or how I can fix it?

Re: [android-developers] Animation support different resolution rate?

 Cary,

Redo your layouts using device-independent units (dp) instead of pixels 
if you use them, and use % values in animation definitions (e.g. animate 
"-100%" to "0%" or some such).

[android-developers] Animation using Matrix + Camera looks dirty...

[Nivek]

Hello,

I have been reusing Rotate3dAnimation.java from the ApiDemo in my own
application to apply a transition between imageviews in a viewflipper.

My problem is that while the animation runs, some frames leave a few
1px vertical lines on the screen black background... (It happens on
both the Emulator 2.0.1 and my htc magic 1.6).

Any idea on how to solve this ?

Thanks !

[android-developers] Animation and flickering - a possible solution

[avigadl]

I have a code that after a TraslateAnimation() ends the layout gets
recomputed (by using AnimationListener). This cause to flickering
effect.

I suspect that this problem  happens since the onAnimationEnd event is
called before the drawing of the last frame.

My solution was to postpone the layout process by a few milliseconds
and set the fillAfter(true) for the animation.

This will persist  the last frame of the animation before the re-
layout.

Hope this helps.

Lidor

[android-developers] Animation on a set of ImageViews

[MikeMike]

I have been trying to find the answer to this question for 3 days
now.  I am developing a game.  And as one progresses in levels, I want
to AlphAnimate each of my imageviews.  So I have an array list of
imageviews.

For iterator i current_game.next()
{
   AlphaAnimation anim = new AlphaAnimation(0.0,1.0)
   anim.setDuration(500);
   i.startAnimation( anim );
}

I want the animation to complete then start the next one, but what is
happening is they are all being animated at the same time.  Please
help!

Thanks

You are calling an Android UI framework method from a background thread, 
and that's not allowed.


The UI portion of the framework is not thread-safe, and the consequences 
are undefined.


This link has a pretty clear description of the issue, as well as proper 
Android code patterns for this:

Thanks, that does help.  I figured it was something like that, I just
couldn't find the correct docs.
Now, I have the problem that my animation won't repeat.
It plays just once.

My onCreate does this:
testAnimation = AnimationUtils.loadAnimation(getBaseContext(),
R.anim.testanim);
testAnimation.setAnimationListener(mAnimationListener);
testAnimation.setDuration(3000);
testAnimation.setRepeatCount(10);
testAnimation.setRepeatMode(Animation.RESTART);

and my onClick does this:
if (running) { // Currently running, stop it
button.setText(R.string.Button01);
testShape.clearAnimation();
} else { // Currently stopped, start it
button.setText(R.string.BtnStop);
testShape.startAnimation(testAnimation);
}

The animation plays exactly once, and the listeners onAnimationStart() is
called exactly once.

Any type of transition will require at least two views - one to hold the 
old value, one for the new one.


With this in mind, use a ViewFlipper with two identical child views to 
represent the two values. Always push the new value into the child 
that's not visible, then animate from the visible/old view to the 
invisible/new one.


If you decide to do it this way, take note of this:

Re: [android-developers] Animation Leaving Trail Using AnimatorSet

[Craig]

Thank you for the offer, but it is part of a larger app that is being made 
for my employer, which I cannot distribute.  If it comes to it though, 
perhaps I can create a small standalone app with just the animation code in 
it.

Try calling invalidate() on the view you are using so that onDraw is called

[android-developers] Animation flicker when change to flipped version.

[ron]

Hi,

I am writing a simple game. I created a sprite sheet for animations,
and I can move the character on the screen left and right. The
character animation graphics on the sprite sheet are all facing
"right".

My approach to make the character face to a different direction is to
created a flipped version of the sprite sheet, and draw the character
depending on its orientation:

playerBitmap = BitmapFactory.decodeResource
(res,sprite_drawable_rid);

sprite_sheet_width = playerBitmap.getWidth();
sprite_sheet_height = playerBitmap.getHeight();

Matrix aMatrix = new Matrix();
aMatrix.preScale(-1.0f, 1.0f);
flippedPlayerBitmap =
Bitmap.createBitmap(playerBitmap, 0, 0,
sprite_sheet_width, 
sprite_sheet_height,
aMatrix, false);

...
if (isFacingLeft()) {
c.drawBitmap(flippedPlayerBitmap, src, dst, null);
}
else {
c.drawBitmap(playerBitmap, src, dst, null);
}

But when the character change direction, the character "flick"
obviously. I am not sure if it is because I don't have an animation
for the transition, or technically I am doing something stupid. Anyone
has any ideas??

thx!
Ron

I'm sure there's a purpose for fillAfter(true), but I have not found it.

If you want the effects of the animation to be permanent, you need to
add a listener to the animation, find out when the animation ends, and
then take steps to make the changes that the animation simulates.

So, for example, if you are sliding a button off of the screen, when the
animation ends, you could make the visibility of that button be GONE, or
remove it from its parent container, or something.

[android-developers] Animation in List, When contents are more

[Nithin]

Hi,

Like in list, if contents are more, it will display the contents by
animation, slowly will come and when the content is complete. It will
stop for a moment and start again. Can anybody tell how to implement
that.

I tried with translate animation. But I can't stop for the moment
after showing full text. Then I tried with translate animation , so
when text is moving, its jerking slowly, not as smooth as in the case
of list. I am using 1.6

[android-developers] Animation on element in a custom view

[swgillan]

Hello,

I have been trying to take one of the elements that I am drawing in a
custom View class and apply an animation on it.

The custom view itself is essentially a background image that I draw
and some overlay images that I am also drawing in the onDraw method
using canvas.drawBitmap(). It is larger then the screen but I can
scroll around and see it. The overlays are sitting on specific
locations of the background image.

Essentially, I am trying to animate one of the overlay bitmaps (just a
simple fade in / fade out with AlphaAnimation). But am having a hard
time only animating that particular element.

The problem I am having is that the animation is being applied to the
entire view, and I just want this one element to be animated. I have
tried using a seperate view for just that overlay, but that creates
other problems, namely when I do this, only the new view will move
with the screen. If there is a away to combine this view with the main
custom view, perhaps that would also help (such that they both move
around).

I am fairly new with Android, so any assistance would be much
appreciated.

Regards,

Steven Gillan

[android-developers] Animation is too slow with xhdpi device.

[btai...@gmail.com]

I've faced problem that animation of view is too slow and with Galaxy
Note which has 1280x800 and 320dpi display.

Actually, I use ScaleAnimation and TransAnimation with RelativeLayout
in code and  I'm pretty sure that code is not incorrect. Size of Image
animated is 67.5 kb.

Device with 800x480 and 240dpi display even shows faster and smooth
anmation than Galaxy Note which has better hardware performance.

I just guess the reason to cause the slow is that devices with high
resolution are slow because they have to make up high quaility UI
suitable for them.

what exact reason caused this problem?
is there  any way to find solution to the problem?
