title: Android - TextView with 'zero' height
body: <p>I would to set dinamically the TextView height with an ObjectAnimator.
  This is the code:</p>
  
  <pre><code>if(condition){
      height = 136;
  }else{
      height = 0;
  }
  ObjectAnimator animator = ObjectAnimator.ofInt(
      mText,
      "height",
      height
  ).setDuration(400);
  animator.start();
  </code></pre>
  
  <p>This works, somwhere, but it <strong>doesn't</strong> set the TextView height to 0, but about 80px. 
  Why?</p>
