title: In the Google Play app, how is the ViewGroup showing the application top lists implemented?
body: <p>The Google Play application presents the top lists of different categories in a GridView-like way (<a href="http://dl.dropbox.com/u/15759867/play.png" rel="noreferrer">screenshot</a>). I'm pretty sure that it's not a standard GridView, since when I scroll all the way to the bottom, it shows a screen-wide "Loading" item, which is not possible with standard GridViews to my knowledge.</p>
  
  <p>Can I find the code for this ViewGroup somewhere? If not what would be the best way to implement such a ViewGroup? I was thinking about handling this with ListView, but it'd require a quite messy adapter that puts multiple list-items in a single row, according to the screen-width available.</p>
