我可以在导航抽屉的片段中使用CollapsingToolbarLayout吗

我正在删除片段上的实际活动工具栏 onResume 并重新启用片段上的活动工具栏 onStop .

请在片段中添加以下代码:

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    ...
    setHasOptionsMenu(true);
    ...
}

@Override
public void onStop() {
    super.onStop();
    final Toolbar toolbar = (Toolbar) getActivity().findViewById(R.id.app_bar);
    getActivity().findViewById(R.id.app_bar).setVisibility(View.VISIBLE);
    ((AppCompatActivity) getActivity()).setSupportActionBar(toolbar);
    ((AppCompatActivity) getActivity()).getSupportActionBar().setHomeButtonEnabled(true);
    ((AppCompatActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}

和

@Override
public void onResume() {
    super.onResume();
    getActivity().findViewById(R.id.app_bar).setVisibility(View.GONE);
    final Toolbar toolbar = (Toolbar) rootView.findViewById(R.id.toolbar);
    ((AppCompatActivity) getActivity()).setSupportActionBar(toolbar);
    ((AppCompatActivity) getActivity()).getSupportActionBar().setHomeButtonEnabled(true);
    ((AppCompatActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
