如何在Android导航组件中隐藏一些片段中的actionbar？

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

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.fragment_menu, menu);
    menu.removeItem(R.id.action_search); // 移除不需要的菜单项
}

@Override
public void onResume() {
    super.onResume();
    ActionBar actionBar = ((AppCompatActivity) getActivity()).getSupportActionBar();
    if (actionBar != null) {
        actionBar.hide(); // 隐藏ActionBar
    }
}
