title: how to get listview id from touchevent
body: <p>Can anyone tell me how I can find the relevant list item id for a touch event associated with a listview?</p>
  
  <p>I want to set the background of a list item to a different color when the user presses down on it, and change it back when they release. I prefer to do this with code and not the background setting.
  I already have an onclicklistener, but want to get this ontouchlistener working as well.</p>
