drawerlayout special framelayout supports navigation drawer.
the child view doesn't have layout_gravity main view. child view has layout_gravity e.g. android:layout_gravity="start" nav drawer.
this means drawerlayout should top level view group. in other words, put layout toolbar inside drawerlayout.
