title: For a ListView adapter, how is getView() called?
body: <p>I've looked around quite a bit but haven't found a real answer to this question. I'm just starting to learn about android adapters and had a few questions. Firstly, do I need to call getView() manually or does it get called automatically? If so, when is it actually called? Lastly, I noticed there's a parameter for "position" with in the list. Is that something I have to increment through iteration or does it get incremented internally somehow?  </p>
  
  <p>thanks!</p>
