to be honest i dont know how to programm apps
I guess it is maybe the most important market for Android.

I dont know about Android much neither Apple.

But I know the biggest market is not being touched  -  still not...

Sometimes ... the simplest things can

[android-developers] Re: Button#onClickListener thread unsafe?

[Piren]

It depends on how android treats onClick events.
According to the behavior seen in his example it seems like that android 
doesn't check whether a view is disabled before running onClick rather 
before queuing it.

So if you manage to dispatch two onClick events to a view before the first 
one was processed (and disabling itself), both will sit in the queue and 
both will be run.

[android-developers] Re: Button#onClickListener thread unsafe?

[Greenhand]

I think I am confused.
If the entire Android UI is completely thread safe and the events are 
queued, the event should be processed one by one. I would like to know why 
an inconsistent state can be seen during the execution even if I do not 
start a new thread in my code.

[G. Blake Meike]

Lew is exactly correct.  The entire Android UI is completely thread safe, 
because it runs on a single thread.  During execution of your program, you 
may, from within the code, be able to see a state that is inconsistent. 
 That is only because you are observing that state from a partially 
processed event.  Each new even will observe consistent state.

... but the main point is that you don't need to worry: unless you 
explicitly start a new thread, looper or asynctask, everything in the UI is 
on a single thread.  It is safe.

[android-developers] Re: button click event listener

[Vivek Punjabi]

Thanks for d reply.
But now my problem is solved.
Actually i wanted the player to click button and then the game should
proceed until it waits for the same player to click button again. But
now got the structure. My fault.

Why don't you set initial visibility of the fields to be "INVISIBLE" and on

Thanks, it works :) I have another question - is there any way to define a 
few buttons as a 1 group, and make 1 animation that will start for this 
group, instead of making an separate animation start for each of them?

[android-developers] Re: Button for dynamic text

[Pavel Dudka]

Really funny, but anyways...

1) You cannot do  " if (PleaseEnter.equals("1")) "
If you want to get String which was entered by user - you need to use
PleaseEnter.getText() method, so your if statement would probably look
like:
if(PleaseEnter.getText().equals("1"))
{
   tv.setText("This is the display 1");
}

2) As I understand, you are experiencing problems when trying to
return something from onClick() - don't do that :) You don't need it -
believe me :)

The code is below I have taken out some of the commented parts that
were above.
public class GenNameActivity extends Activity {
EditText PleaseEnter;

/** Called when the activity is first created. */
@Override
protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
  Button button = (Button)findViewById(R.id.go);
  button.setOnClickListener(mAddListener);
}

private OnClickListener mAddListener = new OnClickListener()
{
public void onClick(View v)
{
 
Toast.makeText(Num.this,stringFunction(),Toast.LENGTH_SHORT).show();
 }
Public string stringFunction();
{
   {
  PleaseEnter=(EditText)findViewById(R.id.PleaseEnter);

  {
  }

  if (PleaseEnter.equals("1")) {
  //tv.setText("This is the display 1.");
  return "9";
  } else if  (PleaseEnter.equals("2")){
//return;

Why not connect the button click event to a function EX

 

public void onClick(View v) {

Toast.makeText(Num.this, stringFunction(),Toast.LENGTH_SHORT).show();

}

 

Public string stringFunction(){

If(whatever){

Return = "Hello";

}

 

 

}

The code in your original post is extremely hard to read. Try a smaller
snippet that illustrates what you're talking about.

 

Have you put in logging and used your debugger to step through and see what
the code is doing?

[android-developers] Re: Button for dynamic text

[Pram]

Well I know some java, but this seems to be the problem
public void onClick(View v) {
when I try to use return in my if statement that does not work
the tv statements do not show anything on the screen when it is
executed.
A suggestion I got was to use the code below, but I am not sure where
to put the first private void, or what to take out of my code.
You can define your own method at Activity level, such as:

private void onTextEdited(String content) {
// deal with the String
}

In the onClick method of your OnClickListener, you can call it such
as:

public void onClick(View v) {
EditText myEditText = (EditText) findViewById(R.id.PleaseEnter);
onTextEdited(myEditText.getText().toString());
}

Re: [android-developers] Re: Button not excepting typeface

[Raghav Sood]

I was a button. I think the problem happened because I changed from a
LinearLayout to a RelativeLayout, and moved the widgets around a bit, as
well as adding a couple of new ones. R.java must not have regenerated
properly and the reset id may have been associated with a TextView
accidentally.

Thanks

Re: [android-developers] Re: Button not excepting typeface

[Raghav Sood]

There's nothing unclear, but according to the docs, the Button inherits the
setTypeface() from the TextView and it should work. However, I get this
exception when using it.

Even the similar questions on StackOverflow on setting the font of the
Button say to use setTypeface(). It doesn't seem to be working though.

I set it like this:

typeFace1 = Typeface.createFromAsset(getAssets(), "fonta.ttf");

final Button button = (Button) findViewById(R.id.reset);

button.setTypeface(typeFace1);


Any idea on how I could set the typeface of the button?

I know the font is fine as I use it in two other textviews and it works
brilliantly. I have tried this on a 2.3 device, and ICS on the Nexus S.
Doesn't work on either.

Perhaps this is what you are looking for?  Never used it so I'm not sure,
but look at this animation property:

[android-developers] Re: Button Animation

[F4L|{0]

for example i find this:

exchangeAnimation.setAnimationListener(new AnimationListener() {
  public void onAnimationStart(Animation anim)
{button.setEnabled(false);}
  public void onAnimationRepeat(Animation anim) {}
  public void onAnimationEnd(Animation anim) {
  LinearLayout.LayoutParams params = new
LinearLayout.LayoutParams(
  LinearLayout.LayoutParams.WRAP_CONTENT,
  LinearLayout.LayoutParams.WRAP_CONTENT);
  button.setLayoutParams(params);
  button.setEnabled(true);}});

but this don't have effect.
sorry for so many questions, but I'm beginner in the field

What did you try? There are numerous functions on View that would appear to

I know that when the animation is ended is called onAnimationEnd of
AnimationListner, but I wasn't able to update update the button
position.

Re: [android-developers] Re: Button Issue

[Mark Murphy]

The button is centered properly, most likely. However, the button background
may have some whitespace at the bottom. Check the button background images
in the SDK.

[android-developers] Re: button id causes app to crash

I got it working, somehow it was crashing because I wasn't assigning
the ID I created for a button to any handler, strange.

I don't know which of these is line 60, but what I would do is replace this
with:

View temp1 = findViewById(R.id.addData);
View temp2 = findViewById(R.id.pickDate);

Then use your debugger see the actual type you're getting for the offending
variable.

mAddCoInfo = (EditText) findViewById(R.id.addCoInfo);
mAddPltInfo = (EditText) findViewById(R.id.addPltInfo);
mAddSquadInfo = (EditText) findViewById(R.id.addSquadInfo);
mPickWeapon = (EditText) findViewById(R.id.pickWeapon);

mPickDate = (Button) findViewById(R.id.pickDate);

deleteModeOn = new ImageView(getApplicationContext());
deleteModeOn.setImageResource(R.drawable.deletenotification);

this is all my code is doing around line 60, could it be that I have a
id for a button in the xml file but I don't have it assigned to a
handler variable assigned to it?

The other thing I found is that sometimes you may need to check all your 
XMLs for any errors, too.  But if its getting a class cast exception and 
you're absolutely positive the ID you're using is the right one, it's 
probably an R generation issue, it may not be ordering the IDs right so 
yours is now pointing to the wrong type of view.

[android-developers] Re: button id causes app to crash

[DB12]

Adam, that makes some sense, I'll investigate it.

I took my app home from work and for some reason it did not crash when
I added that 3rd id (my home comp runs windows 7).  Then I took it
back to work (where we have xp) and it works fine with the extra id.
But then I added another custom dialog with 3 buttons and it crashed
again.

 Try to "Clean" your project and then rebuild it, what is happening here 
most likely is that R.java is not getting re-generated correctly so it is 
using the wrong identifier mapping for your button id.   Another example of 
this type of behavior is when you see the wrong images being loaded right 
after you do some renaming of image resources.

[android-developers] Re: button id causes app to crash

[DB12]

I tried several different id names and none of them worked, but I just
tried my app on a different computer and it worked fine with three
button id's in the dialog (which is what crashed the emulator on my
other one ).  I will try to recreate the problem on the original
computer and post the full log

if im reading it correctly it says "java.lang.ClassCastException:

Not yet.  I would like to avoid an time-consuming and arbitrary number
of tag permutation changes if I can find the proper solution up-
front.  descendantFocusibility does seem to look promising, but I'm
not convince it will work in all of the 6 cases I specified above.

The problem with using the 'normal' ListView OnItemClickedListener()
is that if you have a clickable-button in the list view item, the
ListView item no longer respond to click events at all.
descendantFocusibility may indeed be the answer, but it would be nice
to hear from someone who has all this working.  It should be
completely possible, I am not asking for much here -- just
functionality that you would expect from the list view in the first
place.

I've recently added extra buttons to each row of a listactivity that
can then do whatever, but your case sounds a little more involved.

Re: [android-developers] Re: Button in a ListView cell

[Giorgio Torres]

Eric, I don't know much about Android yet, I just started studying it.
Do you know much of programing concepts? Mainly inheritance?

It happens that,l i think button its not a View, so, you wont be able to add
it to a ListView.

Try build a row composed by a Linear or a Relative layout. Add it your
schemma of the line, with textviews and button. Then use this new row
into your ListView. I think it may work.

I cheer here for you! Feedback me if it works.

It depends on what you mean by 'work'.  I was able to hack things to
work.  The ListView steals focus from the inner-widgets if you set an
OnItemClickListener.  So I had to set an OnClickListener() on the
ListView item View, and a separate OnClickListener() for the child
button.  That works in so much as touch-clicks work, but the trackball/
D-pad is broken for clicks.  Furthermore, I still haven't been able to
figure out how to get the trackball to be able to focus into the
Button instead of the entire list view cell.

So, no, I would not say I have things working to anywhere near my
satisfaction.  I am hoping there is one solution that will allow
everything to work as I would expect it to above, which is in my
opinion that way the UI should function.

[Eric]

and also:

6. The trackball D-pad will ideally allow me to navigate not only to
every cell in the ListView, but also navigate over the clickable
Button and give it trackball focus such that I can run the Button
action from the Trackball.

Re: [android-developers] Re: Button placement problems

[Kostya Vasilyev]

As far as I understand, for you, the background is more important, and 
the buttons should be placed at certain positions within the background.


Well, there is no law that says you have to use layout_margin and dp 
units for positioning your buttons (ImageViews).


Write your own ViewGroup subclass, override onDraw() to draw the 
background with some kind of scaling logic, and override onLayout() to 
position the buttons where they should be .

Adam,

The "in-front/behind" order by default is the order in which views are
declared in the XML file. The order, first to last (XML) becomes back to
front (on screen).

Thanks Vasilyev,


It's "Kostya" (V. is my last name).


The aspect ration is in deed a very important factor - I was surprised
why my layout looks fine in eclipse plug in but corrupts on the
device. Only when I design my own dev config with proper size and
ratio as long it worked correct. I now have a quite similar problem.
Because I have design some images for the background of my buttons (I
use button not imagebuttons to avoid the white 'frame' around the
image). However the images are bigger than I expected them to be.
Using my example - images for B1 and B2 (despite being 240px long) are
much longer than the half of the screen.


If they are in res/drawable, they are considered "mdpi" images (for 320 
by 480 screen size, etc).


If your emulator is higher-res (typical for 480 by 800, etc.), then 
Android will scale those images at load time, by a factor of 1,5 (hdpi 
is 240 pixels per inch, mdpi is 160 pixels per inch).


You should carefully read through "multiple screen support" link you 
referred to in your previous email to understand image resource scaling.


Then I'd recommend you make your layouts work at default resolution & 
density (320 by 480, medium screen density) and only then move onto 
high-density and high-resolution screens.



If I place them with relative
layout they overlap. If I switch to linear layout with weigth 1 the
width is adjusted properly however the height stays the same (I need
to set it manually which I would like to avoid). Can I somehow do it
so the image would resize both its dimensions automatically to keep
it's previous ratio? So that If I fit the images with linear layout
their height would also shrink due to 'forced' shorted width?
You could use ImageView, it has a lot of flexibility for image scaling 
and resizing:


http://developer.android.com/reference/android/widget/ImageView.html

In particular, take a look at these settings: adjustViewBounds, 
cropToPadding, scaleType.


You can set a click listener on an ImageView, and can implement visual 
feedback for when it's touched by using a state-list drawable with 
state_pressed:

Re: [android-developers] Re: Button placement problems

[Kostya Vasilyev]

Here are a few ideas:

1. Create a background that has the maximum possible aspect ratio: it's 
16:9 (1.777) for 480 by 854, and less than that for 480 by 800 (1.66), 
1024 by 600 (1.7) and 320 by 480 (1.5).


Push the background to the top when drawing, so that the bottom part is 
clipped on devices with smaller aspect ratio (320 by 480.


Place the buttons at a fixed position, specified in "dp" units (device 
independent).


This should cover phones, as well as tablets.

2. Scale the background or use a nine-patch.

Implement your own subclass of ViewGroup that can position the buttons, 
calculating their positions based on screen resolution and aspect ratio.


As a further enhancement, create several background at several common 
aspect ratios (I'd pick 1.7 and 1.5).

Serdel,

as suggested here, try using relative layout and you will have to be
more careful about your screens and dimensions with regards to
layouts.
Samsung i5700 is a mdpi device (320x480 pix) and Acer Liquid is hdpi
one(480x800 pix). As a result even though you were using B1's top
margin expressed in DIPs, you would see a shift in the position of it.

Btw, I am from Poland, so Nie ma za co!

You can declare b1 after b2/3 and set layout_above="@id/b2" or "b3".

http://developer.android.com/reference/android/widget/RelativeLayout.LayoutParams.html#attr_android:layout_above

Positioning the top edge of b1 just below the center of the screen is a 
bit more tricky. I wish there were settings for width/height that meant 
"x%" of available space.


What would work is:




 




The invisible view is there just to take up space and push the top edge 
of RelativeLayout to the middle of the screen (this is done by setting 
equal values for layout_weight).


Then there is a top margin on the relative layout to push its top edge 
some more, by a fixed amount.

[android-developers] Re: button on screen that controls page sliding

[Dyno]

I've used the viewflipper along with some of the slide animations to
change a view.  I also used a gesture detector to capture the swipe
input.  The problem with doing it this way is that the gesture is only
an initiator - ie. it wont do any movement of your view until the full
gesture is detected.  See this tutorial for a little help ..
http://www.codeshogun.com/blog/2009/04/16/how-to-implement-swipe-action-in-android/

In the comments it also talks about having a swipe that does something
as your finger moves, however this is beyond me :)

Re: [android-developers] Re: button on screen that controls page sliding

[Vinay Julme]

For going from one Activity to another with animation you can use
overridePendingTransition() but this won't help in drag Have a look at this
tutorial where
I found this guy pretty useful.

Neither ViewFlipper nor ViewSwitcher are designed for that scenario.
At most, they animate the old content off the screen, then animate the
new content onto the screen.

Hi TreKing,

I want to use the ViewFlipper or ViewSwitcher with animation but want
to control the sliding like the sliding drawer button does for the
Android App Menu?

Not a very good tutorial if you can't get it to work :P

I don't know about that, but I would start by looking at setting a footer

Re: [android-developers] Re: Button Mashing Alert Dialog

[Kostya Vasilyev]

 Move the declaration of done_once into the anonynous inner class 
itself, so it's the same variable between first and subsequent calls to 
this function.


The way you had it, as a method-local, meant it was getting created and 
initialized to "false" every time through. In other words, doing nothing.

Re: [android-developers] Re: Button Mashing Alert Dialog

[Lucas Boucher]

Understood and fixed, now onStart is called nowhere in my app.

Here is where my code currently stands, and i can still button mash it.
I am starting to wonder if this will happen on the actual hardware.


gps_init_alt_bld =
new AlertDialog.Builder(this);
gps_init_alt_bld.setMessage(
"GPS Not Initialized Yet.")
.setCancelable(
false)
.setPositiveButton(
"Check GPS Status Again.", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
((AlertDialog)
dialog).getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(false);
*

boolean* done_once = *false*;
*

if*(!done_once)

{
if (latitude == 0 || longitude == 0)
{
gps_initialized=
false
;
dialog.dismiss();
main();
}
else
{
gps_initialized=
true;
dialog.dismiss();
main();
}
}

}
});

Then move "the whole sequence" into another method, that you call from
onStart() and your dialog button.

> Thus I called onStart().

This does not "start the whole program again". What it will do is
confuse the heck out of the Activity base class. Do not do this.

While restarting your activity seems like a wasteful solution, to do
this, call startActivity(getIntent()), followed by finish(). The first
statement should run another copy of your Activity; the second
statement will get rid of your existing copy.

Re: [android-developers] Re: Button Mashing Alert Dialog

[Lucas Boucher]

 Well the overall answer is.
This is my first Droid App and first time using Java. I am an ME and thus
not so professionally experienced on how to layout and plan software. I more
just jump in and start hacking away.  So due to that I made an improper
design decision at the start of this app. Now that I am almost done, i
really don't care to fix it. Everything else in the program works fine,
except this button mashing issue. I don't see how my calls to onStart()
would cause this specific issue and don't want to fix something that isn't
broke just to make code look better.

To explain my overall design that lead me to call onStart()
All my app needs to do is go thru a sequence of checks, gps, gps init,
internet availability, is my location in some list, then display a pic.
If it fails anywhere along the line I wanted to throw a dialog box.
The user can check whatever errored.
Then i just want to run thru the whole sequence again.

So to me, the real answer to any dialog box was to just start the whole
program again.
Thus I called onStart().
If everything was up and running the first time, the whle program would go
the whole way thru without displaying one single dialog box to the user and
the app would finish what it needed to do.

Try having a boolean in your onClick callback class (the anonymous inner
one), and check/set its value before taking action.

Ya, been trying to disable that button, but not having much luck

Currently got this far, but I can still button mash and get multiple alert
