title: DialogFragment layout change animation
body: <p>I have a DialogFragment whose layout params I'm changing from <code>[MATCH_PARENT, WRAP_CONTENT]</code> to <code>[MATCH_PARENT, MATCH_PARENT]</code> on a button click. Basically, the dialog fragment goes from a small dialog to fullscreen. I would like for this to be animated and just not a quick jump. I'm currently just doing in the onClickListener</p>
  
  <pre><code>getDialog().getWindow().setLayout(mExpandedParams.width, mExpandedParams.height);
  </code></pre>
  
  <p>Is there someway I can get the transition to be a smooth animation?</p>
