title: Android -- Gallery with page indicator
body: <p>Has anyone ever put a page indicator at the top of a gallery?  Writing your own gallery and overriding onScroll() doesn't cut it because it only updates while the user scrolls (it stops being called while fling inertia and snapping occurs).</p>
  
  <p>It would be nice if there was an easy way of intercepting all gallery motion, but I haven't seen a way to do this.</p>
  
  <p>Thanks in advance!</p>
