When I finishing my activity, should I use clearAnimation() or stop() on any remaining AnimationDrawable objects?

  • I suppose stop() means end the Animation, and the Animation still be related to the view. While clearAnimation may cancel the animation relative to the view. I haven't test it, just my guess – JohnCookie Feb 22 '12 at 09:46

stop() stops the animation and that's all. Since stop() is method of AnimationDrawable.class you can use it when you want to stop the animation of AnimationDrawable, but not on any View.

clearAnimation() is method of the View.class. It will stop the animation of the View and additionally:

  • If there is AnimationListener defined, AnimationListener.onAnimationEnd(Animation animation) will be called.

  • If there is Handler defined Handler.postAtFrontOfQueue(Runnable r) will be called.

Here is the call hierarchy: View.clearAnimation() -> Animation.detach() -> Animation.fireAnimationEnd() and the fireAnimationEnd() method:

private void fireAnimationEnd() {
    if (mListener != null) {
        if (mListenerHandler == null) mListener.onAnimationEnd(this);
        else mListenerHandler.postAtFrontOfQueue(mOnEnd);
    }
}

  • I used `view.setAnimation(null)` in my case. Neither stop or clearAnimation was doing what I needed. – James Dec 27 '19 at 13:51
