title: Accordion / ExpandableListView on Android
body: <p>I'm trying to create an accordion in Android that has the following features:</p>
  
  <ul>
  <li>Slide animation when opening a tab</li>
  <li>Alignment to the top when opening a tab</li>
  <li>The ability to be used inside a fragment and not inside an activity</li>
  </ul>
  
  <p>Any idea to how to accomplish all these points? I've seen a lot of libraries that however luck of one or more of this points (and I cannot fix the remaining myself :( ).</p>
  
  <p>Any idea? Also pointers to how-to-guides to how to fix the missing points would be really useful! Thanks</p>
