Opening another fragment on RecyclerView item click doesn't hide RecylerView

Question

This uses RecyclerView, NavigationBar and 2 fragments(Home and Bookmark). Home_fragment.xml implements RecyclerView and has 1 FrameLayout to be used as a Layout Container when opening new fragment(Bookmark Fragment). I am using an interface to handle clicks on items.

The problem is when opening new fragment on RecyclerView item click, the fragment opens but remains behind the RecyclerView.

I used recyclerView.setVisibility(View.GONE) inside OnClick method, it works, but i think it hides the RecyclerView permanently, it shows a blank layout when navigating back from Bookmark to Home. To make it visivle when navigating back, i included recyclerView.setVisibility(View.VISIBLE) in OnBackPressed which is in Main_Activity.java, but it abruptly stops the application if i click the back button.

I checked this Fragment doesn't replace and hide another fragment, but using the suggested solution didn't make any difference.

HomeFragment.java

public class HomeFragment extends Fragment implements MyAdapter.OnNoteListener {

RecyclerView recyclerView;
MyAdapter myAdapter;
LinkedList<Data_Items> data_items = new LinkedList<Data_Items>();

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

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

    recyclerView = view.findViewById(R.id.recyclerView);
    recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));

    data_items.add(new Data_Items(R.drawable.a, "Pink", "This is a pink color"));
    // + a few more items         

    myAdapter = new MyAdapter(data_items, this);
    recyclerView.setAdapter(myAdapter);
    myAdapter.notifyDataSetChanged();
}
@Override
public void onNoteClick(int position) {

    Intent intent = new Intent(getContext(), NewActivity.class);
    startActivity(intent);


    FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.replace(R.id.layout_container, new BookmarkFragment());
    fragmentTransaction.addToBackStack(null);
    fragmentTransaction.commit();
}}

fragment_home.xml

More details: I have asked a different question related to this project. Fragment won't open on RecyclerView item click

what is i need to do to make it work?

Just change your FrameLayout elevation ViewCompat.setElevation(View, int) — Anas Mehar, Sep 23 '19 at 13:22
@majidghafouri Check the other question i have asked, it includes all the code https://stackoverflow.com/questions/58049572/fragment-wont-open-on-recyclerview-item-click — User9211, Sep 23 '19 at 13:28
@AnasMehar I put it in OnNoteClick method, but it didn't do anything. The new fragment still opens behind RecyclerView — User9211, Sep 23 '19 at 13:29
@Traveller9211 Then set recyclerview elevation -1 and framelayout 2 — Anas Mehar, Sep 23 '19 at 13:31

This is how i got it working-

activity_main.xml should contain the layout_container (FrameLayout). Nothing else.
HomeFragment.xml should contain the RecyclerView and Navigation drawer
Main_activity.java should have the code to replace the layout_container with HomeFragment Just put the code there no need of any listener.
In HomeFragment.java we can set the listener on RecyclerView items to open the other Fragments/Activities.
