[android-developers] Re: Focus problem in GridView inside Dialog

Just for the record, I resolved the problem. The problem was in
ListAdapter, or rather, the way it interacted with the rest of the
program. As a result, call to getItem() triggered unnecessary list
change notification, which caused this weird behavior.

Cheers,
Piotr
