select an item dynamically in listview

[cool_zephyr]

could anyone tell me how to dynamically select an item in a listview??
i tried
listview.setSelection(1);
and
listview.performItemClick(listview,3,listview.getItemIdAtPosition(3));

both of them don't work..please help me.

Try

ListView.setItemChecked(int position, boolean checked);
