Don't use findViewById() to attempt to find something in rows in a ListView. After all, if you have 20 visible rows, you will have 20+ views named R.id.title. If the row you want to check is the one clicked upon, your CheckedTextView should be the View supplied in the second parameter to onListItemClick(). Just cast it to a CheckedTextView. -- Mark Murphy (a Commons Guy) http://commonsware.com Android Training on the Ranch! -- Mar 16-20, 2009 http://www.bignerdranch.com/schedule.shtml --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
