hit_and_run.java

view.setLayerType(View.LAYER_TYPE_HARDWARE, null);
ObjectAnimator animator = ObjectAnimator.ofFloat(view, "rotationY", 180);

animator.addListener(new AnimatorListenerAdapter() {
   @Override
   public void onAnimationEnd(Animator animation) {
      view.setLayerType(View.LAYER_TYPE_NONE, null);
   }
});

animator.start();
