title: Android 2.1: How to zoom in/out and scroll on a GridView
body: <p><strong>BACKGROUND:</strong>
  My working app contains a GridView with 5 rows of 11 columns with an overridden adapter for display.  It works great for my needs with a large display tablet.  </p>
  
  <p>After porting to a small scale smartphone, I realize that the grid is unusable, due to its small size.  Rather than implement landscape orientation I've decided to use a zoom function.</p>
  
  <p><strong>QUESTION:</strong>
  What is the best way to implement the following 2 basic functions: Zoom (allow zoom between 100 and 400%) and Scroll (up/down/right/left)</p>
