onCreateOptionsMenu inside Fragments

Question

try this,

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

---

Finally, in onCreateView method, add this line to make the options appear in your Toolbar

setHasOptionsMenu(true);

Your already have the autogenerated file res/menu/menu.xml defining action_settings.

In your MainActivity.java have the following methods:

@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) {
        case R.id.action_settings:
            // do stuff, like showing settings fragment
            return true;
    }

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

In the onCreateView() method of your Fragment call:

setHasOptionsMenu(true); 

and also add these 2 methods:

@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;
}

Finally, add the new file res/menu/fragment_menu.xml defining action_1 and action_2.

This way when your app displays the Fragment, its menu will contain 3 entries:

• action_1 from res/menu/fragment_menu.xml
• action_2 from res/menu/fragment_menu.xml
• action_settings from res/menu/menu.xml

I tried the @Alexander Farber and @Sino Raj answers. Both answers are nice, but I couldn't use the onCreateOptionsMenu inside my fragment, until I discover what was missing:

Add setSupportActionBar(toolbar) in my Activity, like this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.id.activity_main);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
}

I hope this answer can be helpful for someone with the same problem.

Call

setSupportActionBar(toolbar)

inside

onViewCreated(...) 

of Fragment

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
    ((MainActivity)getActivity()).setSupportActionBar(toolbar);
    setHasOptionsMenu(true);
}

Set setHasMenuOptions(true) works if application has a theme with Actionbar such as Theme.MaterialComponents.DayNight.DarkActionBar or Activity has it's own Toolbar, otherwise onCreateOptionsMenu in fragment does not get called.

If you want to use standalone Toolbar you either need to get activity and set your Toolbar as support action bar with

(requireActivity() as? MainActivity)?.setSupportActionBar(toolbar)

which lets your fragment onCreateOptionsMenu to be called.

Other alternative is, you can inflate your Toolbar's own menu with toolbar.inflateMenu(R.menu.YOUR_MENU) and item listener with

toolbar.setOnMenuItemClickListener {
   // do something
   true
}

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.activity_add_customer, container, false);
        setHasOptionsMenu(true);
}

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