在片段中不显示选项菜单

Question

我在ViewPager中有两个片段。每个片段都有自己的选项菜单。当我运行应用程序时，首先显示片段一。但是片段中没有显示选项菜单。当我切换到片段时，将显示两个选项菜单。请帮助我。

这是我的片段之一

public class FragmentUz extends Fragment implements MyAdapter.OnItemClickListener{


public FragmentUz() {}

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

@Override
public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    return inflater.inflate(R.layout.fragment_uz, container, false);
}

@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {

    Toolbar toolbar = view.findViewById(R.id.toolbar_one);
    ((AppCompatActivity)getActivity()).setSupportActionBar(toolbar);

}


@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {

    inflater.inflate(R.menu.menu_uz, menu);
    MenuItem searchItem = menu.findItem(R.id.action_search);
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);

    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String s) {
            findFromDb(s);
            return true;
        }

        @Override
        public boolean onQueryTextChange(String s) {
            findFromDb(s);
            return true;
        }
    });
    super.onCreateOptionsMenu(menu, inflater);
}
}
