Thanks. Preferably, modify the ArrayAdapter using add() rather than modifying the backing ArrayList. The ArrayList will not notify the ArrayAdapter of any changes (because there's no way for it to do so), so the ArrayAdapter will not realize there is new material. You could also try calling ArrayAdapter#notifyDataSetChanged() or notifyDataSetInvalidated(), to see if either one of those causes the ArrayAdapter to refresh from the updated ArrayList. I have not tried either of those, and they are undocumented, but they sound promising... -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
