当一个片段调用另一个片段时，如何使用新片段更新导航抽屉列表

Question

当我的“家庭片段活动”正在从自身调用另一个片段时，如何更新导航抽屉。 我已经在我的家庭片段活动中创建了卡片视图，因此当我在片段活动中按下卡片时，onClickListener会被调用，但是我的问题是我的导航抽屉项没有对应于该片段进行更新，因此如何在何时更新导航抽屉一个片段叫另一个片段。

HomeFragment活动

public class HomeFragment extends Fragment {

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

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        ((NaviActivity)getActivity()).setActionBarTitle("Home");

        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_home, container, false);
    }

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

        view.findViewById(R.id.home_home_fragment).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getActivity(),"You are already at Home ;)",Toast.LENGTH_SHORT).show();
            }
        });

        view.findViewById(R.id.discussion_home_fragment).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Inflating Discussion Frag from Home Frag
                Fragment someFragment = new DiscussionFragment();
                FragmentTransaction transaction = getFragmentManager().beginTransaction();
                transaction.replace(R.id.fragment_loader, someFragment ); // give your fragment container id in first parameter
                transaction.addToBackStack(null); // if written, this transaction will be added to backstack
                transaction.commit();
                Toast.makeText(getActivity(),"You are now in Discussion Fragment ;)",Toast.LENGTH_SHORT).show();

            }
        });

        view.findViewById(R.id.events_home_fragment).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Inflating Events Frag from Home Frag
                Fragment someFragment = new EventsFragment();
                FragmentTransaction transaction = getFragmentManager().beginTransaction();
                transaction.replace(R.id.fragment_loader, someFragment ); // give your fragment container id in first parameter
                transaction.addToBackStack(null);  // if written, this transaction will be added to backstack
                transaction.commit();
                Toast.makeText(getActivity(),"You are now in Activity Fragment ;)",Toast.LENGTH_SHORT).show();
            }
        });
        super.onViewCreated(view, savedInstanceState);
    }
}
