If you really really do, you could alternative expose it as a public method in the Activity then instead of passing it to the fragment, access your activity in the fragment (onAttach or onActivityCreated or something) and get the list data, which would be the actual list both objects would share. ------------------------------------------------------------------------------------------------- TreKing <http://sites.google.com/site/rezmobileapps/treking> - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
