Romain, Thanks for your response. I'm not sure if that approach will work, though. My ListActivity's onListItemClick() method is called when I click on an item with the trackball, but *not* when I touch it.
Perhaps the root problem is that my list rows have focusable items in them (check boxes). The built-in Alarm Clock application has something similar, though, and I can see from the source code that Alarm Clock sets individual click listeners on the check boxes and the clock views. I'm trying to get the same behavior as Alarm Clock, where tapping on a list row brings up an activity to edit the row, and the check box can only be selected by tapping on the check box itself. I think that precludes using multiple-choice mode for the list view, correct?
