hasExplicitFocusable
Returns true if this view is focusable or if it contains a reachable View for which hasExplicitFocusable returns true. A "reachable hasExplicitFocusable()" is a view whose parents do not block descendants focus. Only VISIBLE views for which getFocusable would return FOCUSABLE are considered focusable.
This method preserves the pre-O behavior of hasFocusable in that only views explicitly set focusable will cause this method to return true. A view set to FOCUSABLE_AUTO that resolves to focusable will not.
Return
true if the view is focusable or if the view contains a focusable view, false otherwise
Parameters
view
view on which to make the change.
