Here is the actual bug related to this issue http://code.google.com/p/android-misc-widgets/issues/detail?id=8
This basically states that the onAnimationEnd method doesn't really work well when an AnimationListener is attached to an Animation
The workaround is to listen for the animation events in the view to which you were applying the animation to
For example if initially you were attaching the animation listener to the animation like this
mAnimation.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationEnd(Animation arg0) {
//Functionality here
}
});
and then applying to the animation to a ImageView like this
mImageView.startAnimation(mAnimation);
To work around this issue, you must now create a custom ImageView
public class MyImageView extends ImageView {
and then override the onAnimationEnd
method of the View class and provide all the functionality there
@Override
protected void onAnimationEnd() {
super.onAnimationEnd();
//Functionality here
}
This is the proper workaround for this issue, provide the functionality in the over-riden View -> onAnimationEnd method as opposed to the onAnimationEnd method of the AnimationListener attached to the Animation.
This works properly and there is no longer any flicker towards the end of the animation. Hope this helps.
