Any of those help Since your NavigationDrawerFragment is statically declared in your layout, it is being instantiated as the Activity is laid out - i.e., upon the call to setContentView() - and its onCreateView() method is running before your call to setArguments(). Furthermore, setArguments() cannot be called on a Fragment once it has been attached to an Activity, which is happening automatically because of the Fragment's static declaration. If you want to pass data to an already active Fragment, a simple way is to create a public method in its class, and call it on the instance after its initialization.

this one helps. So like I mentioned in the title, I have a setup with a NavigationDrawerFragment and another fragment in a containing activity. , In your Activity let have this:

code :

@Override
public boolean onCreateOptionsMenu(MenuInflater inflater, Menu menu){
  boolean onlyFragments = !mDrawerLayout.isOpened(GravityCompat.START);
  Fragment visibleFragment = getSupportFragmentManager().findFragmentById(R.id.content_layout);
  visibleFragment.setHasOptionsMenu(onlyFragments);
  if(onlyFragments){
    return super.onCreateOptionsMenu(inflater,menu);
  }else{
     //here only activity inflates menu
     inflater.inflate(R.menu.activity_menu, menu);
     return true;
  }
}
