I'm trying to extend BaseAdapter and Edit Data in that extension. (full
source code to class is below) I'm having several focus issues. The first
issue is that I must touch the "EditText" field several times to get focus.
On the Droid X the soft keyboard never shows. On the ADP2 once I type one
letter the auto complete bar shows for a moment then disappears, then I lose
focus for the field I was just editing.
