title: Setting focus programatically in ExpandableListView. Emulating D-pad clicks in code?
body: <p>I have subclassed ExpandableListActivity to create an activity that
  presents a simple tree view of the 'world at large' and allows the
  user to select one for further use by the app. I am having trouble
  setting focus programatically. One thing that baffles me is that I can
  use the D-pad to set focus on any of the child or group items in my
  ExpandableListView, but inside my onChildClick() callback,
  isFocusable() returns false. If I can set focus with the D-pad, how
  can isFocusable() return false?</p>
  
  <p>My goal is to avoid having the user have to touch individual
  ExpandableListView entries to select them and to provide a couple of
  buttons to move the focus up and down inside the list. I  want
  selection to be easy for  folks with no D-pad or with a phone that
  only presents the D-pad when in landscape mode (e.g. Droid) .</p>
  
  <p>Is there some way I can programatically inject D-pad key clicks into
  my app input event stream?</p>
