title: Forbid GridView to load all views at once
body: <p>I have about 700 items to display in the grid view.</p>
  
  <p>On a Samsung Galaxy Tab 10.1 this is not a problem: it has enough memory.
  On a HTC Explorer the heap is overflown.</p>
  
  <p>So I want to load data dynamically regarding current scroll position (N rows for screen + 5 rows as a tail). And I want to show a scrollbar which represents the position in total rows. But I don't want to draw items that I don't see.</p>
  
  <p>In other words, I want to create something similar to <code>UITableView</code> in iOS. How can I do this?</p>
