Android view animation stops when view out of screen

Question

I'm having a recyclerView with several views and one is the animation view which has an animation applied to it. Once the view is out of the screen the animation is no longer active, even though the animation still exists.

The data:

rotate_around_center_point.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false" >

    <rotate
        android:duration="2500"
        android:interpolator="@android:anim/linear_interpolator"
        android:pivotX="50%"
        android:pivotY="50%"
        android:repeatCount="infinite"
        android:repeatMode="restart"
        android:toDegrees="360" />

</set>

Applying animation:

                animation = AnimationUtils.loadAnimation(this.getContext(),
                        R.anim.rotate_around_center_point);
                loadingRotatingCircleIV.startAnimation(animation);

I could not find any way to catch an event when the animation is interrupted so I'm able to restart the animation once it was out of the screen.

Answer 1

RecyclerView is incorrectly stopping animation on the view when view goes out from screen only if you apply View Animation to that view. If you will use Property Animation everything works properly. So the following solution will work:

ObjectAnimator animator = ObjectAnimator.ofFloat(loadingRotatingCircleIV, "rotation", 0.0f, 360.0f);
animator.setDuration(1000L);
animator.setRepeatCount(ObjectAnimator.INFINITE);
animator.setInterpolator(new LinearInterpolator());
animator.start(); 

Answer 2

If you want to use a ViewAnimation for a RecyclerView item, you have to restore animation in overriden method of RecyclerView - onViewAttachedToWindow(ItemViewHolder holder), like:

@Override
public void onViewAttachedToWindow(ItemViewHolder holder) {
    super.onViewAttachedToWindow(holder);

    if (holder.animated) 
    {
        Animation anim = new ScaleAnimation(0.8f, 1.2f, 
            0.8f, 1.2f,
            Animation.RELATIVE_TO_SELF, 0.5f,
            Animation.RELATIVE_TO_SELF, 0.5f);
        anim.setFillAfter(true);
        anim.setInterpolator(new BounceInterpolator());
        anim.setDuration(1100);
        anim.setRepeatCount(Animation.INFINITE);
        anim.setRepeatMode(Animation.REVERSE);
        holder.animatedView.startAnimation(anim);
    }
}
