The last version of WhatsApp does what I'm talking about. When you scroll between tabs the toolbar shows different menu options. I can implement ViewPager with adapter and fragments but not this. How could it be done? I really don't know what kind of trick is behind. It changes everytime you switch pages

you have to override `onCreateOptionsMenu` on each fragment – Blackbelt Jun 04 '15 at 16:54

it's not something only activity can do? – user3290180 Jun 04 '15 at 17:03

no it is not. Fragment has also this possibility. Don't forget to call `setHasOptionsMenu(true);` in onCreate of your Fragment – Blackbelt Jun 04 '15 at 17:05

In each Fragment you have to override onCreateOptionsMenu, with different menu/menu.xml files
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
menu.clear();
inflater.inflate(R.menu.menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
Don't forget to call setHasOptionsMenu(true);, in onCreate of your Fragment
