You didn't say what the error was, or provide any of your onCreate() source code. So, I can only comment on what I see unusual in this layout. If you wish to use the magic identifier for use with ListActivity, that is "@android:id/list" and can only appear once, whereas you are trying to use it twice. Likewise, if you want the magic identifier for what to display for an empty list, it is "@android:id/empty", and it should only appear once. If you really do want two ListViews in here, then: -- You'll need them to have distinct identifiers, probably of the form "@+id/list1" and "@+id/list2" -- I'm not sure the "@android:id/empty" trick will work -- you might need to implement that yourself via a ViewFlipper or making the ListView invisible or something -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 1.3 Published! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
