title: Understanding BaseAdapters and how to use them
body: <p>I'm trying to set up a an image GridView Layout, and this involves deriving a new class from the BaseAdapter class. I have been using the tutorial on the website developer.android.com, but I still don't quite understand what it means. Could someone please explain to me what exactly is a BaseAdapter? I don't understand the definition provided by the Android developers website.</p>
  
  <p>Thanks</p>
