Answer 1

You can override the onMenuCreated method and by managing the flag of which tab you're in, create a menu item accordingly. The menu item should be set to show as action button (so it will be visible in the action bar).

Another approach is to create a toolbar layout, add the two buttons and manage their visibility.
