If nothing else, you can fake it. For example, you can add new data to a MatrixCursor whenever, and a CursorAdapter will reflect the changes. Similarly, I have an EndlessAdapter: http://github.com/commonsguy/cwac-endless/tree/master It wraps another adapter and makes it easier to offer an "endless" list, where more data is loaded in when the user scrolls to the bottom. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Need help for your Android OSS project? http://wiki.andmob.org/hado --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
