animationdrawable

I was following the Google provided example of how to use AnimationDrawable with an ImageView. You can find it here: http://developer.android.com/guide/topics/graphics/drawable-animation.html imageView.setBackgroundResource(R.drawable.animation); AnimationDrawable animation = (AnimationDrawable)imageView.getBackground(); animation.start(); When I run it I get the error: java.lang.ClassCastException: android.graphics.drawable.BitmapDrawable cannot be cast to android.graphics.drawable.AnimationDrawable Google seems to think this should work, but if you cannot cast a BitmapDrawable to

I want to create an simple animation by changing frames inside an ImageView. I don't want to use AnimationDrawable because i need to receive events when a frame changed or when the animation stoped, to be able to play it backwards, restart it and so on. My problem is that the frames doesn't actually change event though setImageDrawable gets called (on the main thread). So everythings seems to work fine excepts that the frames doesn't change (actually just a frame is drawn, the first one). So my code: public class AnimatedImageView extends ImageView implements Animatable, Runnable { private

when we scroll, the foreground of the home screen (icons, widgets, etc.) moves to the left or right by the full screen width, but the background image (or live wallpaper) only moves by a fraction of that width. My question is how get this effect. till now have done this.

Is there any solution about how to animate the .gif images in android application? To give a precise and complete answer here is what you need to do step wise: You would need to have different .png images which will act as frames for your animation. Save them in res/drawable folder. Create anim.xml file in res

How do I pause frame animation using AnimationDrawable? I realize this thread is quite old, but since this was the first answer on Google when I was searching for a way to pause an animation, I'll just post the solution here for someone else to see. What you need to do is subclass the animation type you'd like to use and then add methods for pausing and resuming the animation. Here is an example for AlphaAnimation: public class PausableAlphaAnimation extends AlphaAnimation { private long mElapsedAtPause=0; private boolean mPaused=false; public PausableAlphaAnimation(float fromAlpha, float
