title: How can I repeat a property animation?
body: <p>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?</p>
  
  <pre><code>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) {
      }
  });
  </code></pre>
