title: Simulate iOS 4 folder animation in Android
body: <p>I'm trying to simulate the iOS4 folder appearance in Android. I have a Button in my layout, and when pressed I would like to <code>expand</code> a View with some other buttons or images and the rest of the screen pushed down.</p>
  
  <p>Here's an example video showing how the iOS 4 folders works: <a href="http://www.youtube.com/watch?v=Z6ZwC8TGwXo" rel="nofollow">http://www.youtube.com/watch?v=Z6ZwC8TGwXo</a> (0:44)</p>
  
  <p>Is there any library or sample code on anything similar to this? Or maybe some indications on how to achieve this?</p>
  
  <p>Greetings</p>
