title: 3 by 3 grid with image button in each cell on Android
body: <p>I want to have a grid with 3 columns and 3 rows and an image button in each cell (center of cell).</p>
  
  <p>I tried with gridview but I can't fix the number of rows.
  I tried with a tablelayout and 3 tablerows, but I can't change width/height at runtime</p>
  
  <p>Any ideas?</p>
