[android-developers] Question about animation
Hi.
Hi have an absolute layout with pictures.
Only 2 pictures are show simultaneously. Others are on the layout, but
out of view.
I wan't on user click to show others picture.
For this, I do an animation to translate the layer.
For translation from right to left, it works correctly : an other
picture come from right progressively while another exit on left side.
But, for translation from left to right, it don't work : the right
picture exits correctly on right side, but left picture only appear on
left side at the end of the animation.
while translating, an empty space appear on left until the end of
translation.
For translating, I make my own animation (not taken from XML because it
depends on image size) :
scrollLeft = new TranslateAnimation(0, -(pictoWidth+hspace), 0, 0);
scrollLeft.setDuration(300);
scrollLeft.setAnimationListener(this);
scrollRight = new TranslateAnimation(0, (pictoWidth+hspace), 0, 0);
scrollRight.setDuration(300);
scrollRight.setAnimationListener(this);
then, for translating, I do :
layout.startAnimation(scrollRight);
(I join the widget source in case somebody is interesting on doing the
same thing ...)
Does somebody have any idea how tohave the same effect on left to right
scroll than right to left ?
Thanks in advance.
Mike
PS: I can't use filpper because I have to picture visible at the same
time and only one disappear at a time.
It ould be possible but more complicated I thing ...

[android-developers] Question About animation
Hi, I want to move a view from location (x,y) to (x1,y1). What is the best way to do it? I tried using the following code but it cannot stay at the last point (x1,y1),it always translate back: TranslateAnimation anim = 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); anim.setDuration(100); anim.setInterpolator(new LinearInterpolator()); this.startAnimation(anim); any suggestions? thanks Z -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Question about animation
Hello, i would animate a VideoView what scales up and switch then to fullscreen. My code looks like: final VideoView videoView = (VideoView) findViewById(R.id.video_view); final ObjectAnimator x = ObjectAnimator.ofFloat(this, "x", 0); x.setTarget(videoView); final ObjectAnimator y = ObjectAnimator.ofFloat(this, "y", 0); y.setTarget(videoView); final ObjectAnimator scaleX = ObjectAnimator.ofFloat(this, "scaleX", 2); scaleX.setTarget(videoView); final ObjectAnimator scaleY = ObjectAnimator.ofFloat(this, "scaleY", 2); scaleY.setTarget(videoView); final AnimatorSet set = new AnimatorSet(); set.setInterpolator(new LinearInterpolator()); set.setDuration(1000); set.playTogether(x, y, scaleX, scaleY); Unfortunately nothing happens. I am happy to read suggestions. Thanks in advance Daniel -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Re: [android-developers] Question About animation
You simply need to use setFillAfter(true).

Otherwise, setFillAfter() moves the pixels, but the "hot spots" for interaction remain at the old location. For interactive widgets, you should set up an AnimationListener, and when the animation ends, modify the layout to have the widget reside at your desired new location. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android Training...At Your Office: http://commonsware.com/training -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Re: [android-developers] Question about animation
I doubt that will work, as VideoView is backed by a SurfaceView, which doesn't play by the same rules. On Android 4.0, you could try replacing the VideoView with a MediaPlayer and a TextureView. TextureView can be animated, IIRC. On Tue, Jan 24, 2012 at 7:27 AM, Daniel Rindt wrote: > Hello, > > i would animate a VideoView what scales up and switch then to fullscreen.

Re: [android-developers] Question about animation
Thanks for your quick answer, i have API Level 11 available for the application, so the compatibility package may help here? Another idea is to render one frame of the video in a hidden fullscreen element, then shrink it down and animate it. I think poeple can neglect that the video is not playing in the zoom animation.
