title: Android Spinner Reveal Animation Material Design
body: <p>I just need something pretty simple.
  Can't find any guide/resource online that will help me to achieve the <a href="https://dl.dropboxusercontent.com/u/48976508/components-menus-usage-061001_Textfield_Dropdown_xhdpi_003.webm" rel="noreferrer">following behaviour</a>:</p>
  
  <p>So there are 3 things:</p>
  
  <ol>
  <li>A Ripple that appears to be bounded to the view</li>
  <li>Scale up animation of the popup (Can't find a way to customize it)</li>
  <li>The text is carried over from the Spinner field to the actual popup</li>
  </ol>
  
  <p>Any help is appreciated .</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>The ripple is actually a straight forward thing that can be found in the docs. The scale up animation of the popup dropdown is what interesting me the most. If I only could get a reference to that popup , I could animate it however I want... Ideas anybody ?</p>
