title: GridView-like Android widget with variable lengths
body: <p>Is there an existing Android widget third-party implementation that looks like a <code>GridView</code> but supports variable height items? I need one for images, but of course one that works with arbitrary views will work. Memory management is important, such that the Views and the bitmaps may be recycled.</p>
  
  <p>Or, a way to convert <code>GridView</code> source code to do this?</p>
  
  <p>An example of the grids:</p>
  
  <blockquote>
    <p>1A 2A 3A </p>
    
    <p>1A 2A 3B </p>
    
    <p>1A 2B 3C</p>
  </blockquote>
  
  <p>The first column contains 1 item labeled as 1A (relative height 1), the second one contains two items labeled as 2A (relative height 2/3) and 2B (relative height 1/3). The third column contains three items (all of them with relative height 1/3).</p>
