Button ClickListener not working Fragment to Fragment

[mwapevi]

I have created the 2 fragments, fragment_contact.xml and fragment_contacts3.xml along with their activity classes, fragment_contact.xml (Contact.java) as the button to which I added a clicklistener to fragment_contacts3.xml (Contacts3.java). However, the issue is that that Button click is not working as it supposed to take me to the next fragment.

How do I resolve this issue?

The following is the Contact.xml:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/black" android:orientation="horizontal" android:id="@+id/fraglayout" tools:context=".ui.home.Contacts">

The following is the Contact.java along with clicklistener:

public class Contacts extends Fragment {

private BottomNavigationView bottomNavigationView;
private ImageView back;
private RadioGroup radioGroup;
private LinearLayout linearLayout3;
private RadioButton bt1, bt2;
private Button nextBtn;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.fragment_contacts, container, false);
    bottomNavigationView = container.getRootView().findViewById(R.id.nav_view1);
    bottomNavigationView.setVisibility(View.GONE);
    nextBtn = view.findViewById(R.id.nextbtn);

    nextBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
          Intent i;

          startActivity(i=new Intent(getActivity(), Contacts3.class));
        }
    });

    return view;
}

@Override
public void onDestroyView() {
    super.onDestroyView();
    bottomNavigationView.setVisibility(View.VISIBLE);
}

@Override
public void onResume() {
    super.onResume();
    Objects.requireNonNull(((AppCompatActivity) requireActivity()).getSupportActionBar()).hide();
}

@Override
public void onStop() {
    super.onStop();
    Objects.requireNonNull(((AppCompatActivity) requireActivity()).getSupportActionBar()).hide();

}

@Override

    super.onDestroy();
    Objects.requireNonNull(((AppCompatActivity) requireActivity()).getSupportActionBar()).show();
}
