You need to build a sub-class of ListActivity. Then you can override onListItemClick to catch the event on click when the list item is clicked. But that is not always working, if you use your custom list adapter and inside the adapter has any button, check box and image button. If the adapter has this kind of checkable item, they seems to be catch the click event before onListItemClick. So onListItemClick is not work.

I found this problem when I build my AdvGen To Do List.
