title: Android ValueAnimator onAnimationUpdate doesn't work correctly
body: <p>It doesn't work correctly when I use a property animation. The following is my code. Click a view to perform a toggle animation, but it didn't come to the expected result.The log shows the callback of "onAnimationUpdate" was called only twice and returned the max value.</p>
  
  <pre><code> @Override
   public void onClick(View v) {
       switch (v.getId()) {
          case R.id.product_item_top_rl: 
          startAnimation(v);
          break;
       }
   }
  
  
  private void startAnimation(final View v) {
      int height = v.getHeight();
      ValueAnimator va = ValueAnimator.ofInt(0, height);
      va.setDuration(1000);
      va.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
          public void onAnimationUpdate(ValueAnimator animation) {
              Log.d(TAG, "animation : " + animation.getAnimatedValue());
              v.getLayoutParams().height = (Integer) animation.getAnimatedValue();
              v.requestLayout();
          }
      });
      va.start();
  }
  </code></pre>
  
  <p>Here is the LOG.</p>
  
  <pre><code>D/ChooseProductFragment: animation : 150
  D/ChooseProductFragment: animation : 150
