temporary fix for selection on 2.x
Fixed Android 2.x Bug for selection in ActionMode

- hack: triggers events directly in onInterceptTouchEvent in
DragAndDropListView. This is necessary because getView() is not always
triggered automatically
removed unnecessary code
fixed test

events in listview now only triggered in actionmode
set button not clickable
