title: Slide down view in android
body: <p>I would like to have a button in my android application trigger a slide down view of a form.  I want to have a view at the top of the screen, a list at the bottom of the screen, and I want to have the slide down form view appear between the two when a button is clicked.  </p>
  
  <p>I have no problem showing the view, but can't seem to animate it from hidden to shown on the screen.  </p>
  
  <p>Any ideas on how this could work?</p>
