title: Double Tap to Top
body: <p>I have seen this new feature in my <code>Samsung Galaxy S3</code> called <code>Double Tap to Top</code> where on scrolling to the bottom of the <code>listView</code> the user needs not scroll back to top he just needs to Double tap on top of the phone/device and it automatically scrolls back to the top.
  Is there any possibility I can do similar to that with my <code>custom listView</code> inside my application also?
  I have googled but couldn't find a solution.
  Can anyone help me with this?</p>
