title: Android Swipe Refresh Layout scroll up to refresh
body: <p>I've implemented a swipe refresh layout for my grid view and it works perfectly if I pull (scroll) downwards for the refresh to be called.  </p>
  
  <p>However, I'm trying to figure out how to refresh when the user scrolls up.  So when the user reaches the last of the items in the grid (my limit is 10) so when the user sees all ten and then pulls upwards or tries to continue to scroll how can I then refresh?</p>
  
  <p>Any help is appreciated.</p>
