Days pass but I still can't find an answer.
I try to trace stack, but I can't understand how the system get
"position" parameter since the source code of SDK is not available:
ListView.performItemClick(View, int, long) line: 2968
AbsListView$PerformClick.run() line: 1406
When I call View.PerformClick, SDK says "You shouldn't call this."
I have a way to call performItemClick directly, but I don't know how
to get position on a ListView using MotionEvent information.
After all, why if I override ListActivity.dispatchTouchEvent,
ListActivity.onListItemClick will become disable? Is this a bug?
Should I report it to google?
