Android: AnimatedVectorDrawable Loop

Question

I'm playing around with AnimatedVectorDrawables using https://shapeshifter.design/ The exported file I got is below. My research Tells me that in order to loop an animations i should add android:repeatCount="infinite" and android:repeatMode="restart" to the objectAnimator.

Adding this to the objectAnimator only repeats one of these items out of series. How would I loop the entire series of animations? I want the animation to start on load and repeat.

My java code for implementing the Animation is as follows:

final ImageView animationView = (ImageView) findViewById(R.id.animationView);
final AnimatedVectorDrawable drawable = (AnimatedVectorDrawable) getDrawable(R.drawable.avd_dice);
animationView.setImageDrawable(drawable);
drawable.start();

Answer 1

You should use AnimatedVectorDrawableCompat instead of AnimatedVectorDrawable to support lower APIs then you can also write that callback and start animation when it ends. Finally your code should be like this:

val animated = AnimatedVectorDrawableCompat.create(this, R.drawable.avd_dice)
    animated?.registerAnimationCallback(object : Animatable2Compat.AnimationCallback() {
        override fun onAnimationEnd(drawable: Drawable?) {
            animationView.post { animated.start() }
        }

    })
    animationView.setImageDrawable(animated)
    animated?.start()

Answer 2

You can use Animatable2.AnimationCallback and start the AnimatedVectorDrawable animation again in onAnimationEnd

drawable.registerAnimationCallback(new Animatable2.AnimationCallback() {
    @Override
    public void onAnimationEnd(Drawable drawable) {
        avd.start();
    }
});

drawable.start();
