Can you post some code as to how you are replacing the fragments? Are you unsing FragmentTransaction .replace()? How is your xml setup/how do you initialize the fragments? – Correspond

Best way is to have all the menus in one single file and inflate in activity. After loading Fragment from Activity call invalidateOptionsMenu() and then in onPrepareOptionsMenu() handle the visibility of respective menu items. – Willenewillet

@Jogendra Gouda, have you tried my solution ? – Magdalenemagdalenian

Not possible AFAIK, you will have to name it differently though can keep value/title same. – Dramamine

Answer 1

Just call invalidateOptionsMenu() on onCreate().

More reference check this one.

Hope this will help you.

This is how your activity will be

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        switch (id) {
            //your menu item 
                return true;
        }

        return super.onOptionsItemSelected(item); // important line
    }

In your fragment onCreateView() method

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        setHasOptionsMenu(true); //imp line
        return inflater.inflate(R.layout.fragment_following, container, false);
    }



@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.fragment_menu, menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    switch (id) {
        case R.id.action_1:
            // do stuff
            return true;

        case R.id.action_2:
            // do more stuff
            return true;
    }

    return false;
}

Just after replacing the fragment(or commiting the fragment transaction), you have to declare that option menu has changed, you can do so by calling invalidateOptionsMenu(). The onCreateOptionsMenu(Menu) method will be called the next time it needs to be displayed.

NOTE: you would need to call supportInvalidOptionsMenu in case if you are using AppCompat support library.
