[android-developers] Re: Need help on List Adapter

My main thought on glancing at this is: you are more likely to get the
help you want if you tell us more. What, for example, do you expect
NotifyDataSetChanged() to do? What data has changed, and what View are
you expecting needs to be updated to reflect the change?

Maybe you will luck out and find a reader more willing to do "code
diving", but I am not in the mood to reverse-engineer your code to
figure out the answers to these questions tonight myself.
