Implement menu in fragment in Android studio

Question

I want to implement menu in fragment class. The fragment works fine and there is not error but there is no menu shown in the fragment. I am implementing the class in the following way

public class FilesFragment extends Fragment {

    public FilesFragment() {
        // Required empty public constructor
    }

    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        view = inflater.inflate(R.layout.fragment_files, container, false);

        return view;
    }

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        setHasOptionsMenu(true);
        super.onCreate(savedInstanceState);

    }

    @Override
    public void onCreateOptionsMenu(@NonNull Menu menu, @NonNull MenuInflater inflater) {
        inflater.inflate(R.menu.files_menu,menu);
        super.onCreateOptionsMenu(menu, inflater);
    }
     @Override
     public boolean onOptionsItemSelected(@NonNull MenuItem item) {
    int id = item.getItemId();
    if (id == R.id.action_setting){
        Toast.makeText(getActivity(),"setting clicked",Toast.LENGTH_SHORT).show();
    }
    return super.onOptionsItemSelected(item);
}

}

and this is the xml file of files_menu in menu folder.

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/action_setting"
        android:title="settings"
        app:showAsAction="never"/>
    <item
        android:id="@+id/aobut"
        android:title="About"
        app:showAsAction="never"
        />

</menu>

The above code is not showing the menu at all. How do menu is implemented in the fragment?

Answer 1

You can populate the menu in any view without any complexity. Use the following code and enjoy.

any View can be a button, imageView or any other else in which you want to inflate this menu. No need to add menu in xml. Just do in java

    PopupMenu popup = new PopupMenu(context, any View);
    popup.inflate(R.menu.files_menu );
    popup.setOnMenuItemClickListener(item -> {


        int id = item.getItemId();

        if (id == R.id.action_setting) {
            // do stuff
        } else if (id == R.id.aobut) {
            //

        } 


        return true;
    });
    popup.show();
