How can I repeat a property animation?

Question

I'm doing an animation of bubbles on the screen, but the bubbles stop after finishing the animation time. How do I repeat the animation or make it infinite?

bub.animate();
bub.animate().x(x2).y(y2);
bub.animate().setDuration(animationTime);       
bub.animate().setListener(new AnimatorListenerAdapter() {

    @Override
    public void onAnimationStart(Animator animation) {
        animators.add(animation); 
    } 

    @Override
    public void onAnimationRepeat(Animator animation) {
    }

    @Override
    public void onAnimationEnd(Animator animation) {
    }
});

Since ViewPropertyAnimator is only good for simple animations, use more advanced ObjectAnimator class - basically method setRepeatCount and additionally setRepeatMode.
