The LinearLayout contains the Menu Item view, if there is a Menu Item view in LinearLayou, it will be reused in next show, If there is no enough menu item view in LinearLayout, the new one will be created. The problem as I described, the GONE menu item view has incorrect View Id which is provided in XML layout. they are cleared with 0 or -1 after PopupWindow is dismissed. I don't know what's happened, what's the mechanism of Android View design.
Your any help are appreciated!
