1. The clearFocus routine in ViewGroup was clearing the pointer to the descendant which has focus after calling clear focus on that child. However, currently clearing the focus of a view causes the view that loses focus to try to give the focus to the first focusable which potentially sets the pointer to the child that has input focus in the ViewGroup but the ViewGruop essentially clears that pointer. This resulted in having two focused views at the same time in some cases. 2. AbsListView was not calling the super implementation of add focusables if the focus type was not accessibility. bug:6559819 Change-Id: I478dfed000b5de3f9b15e12eb82aa3d34c2301e4
