Take three Fragments like HomeFragment,DashboardFragment and NotificationFragment and three layouts for those three fragments.

HomeFragment

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

fragment_home.xml

**DashboardFragment **

public class DashboardFragment extends Fragment {
    public DashboardFragment() {
    }
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_dashboard, container, false);
    }
}

fragment_dashboard.xml

**NotificationFragment **

public class NotificationFragment extends Fragment {
    public NotificationFragment () {
    }
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_notification, container, false);
    }
}

fragment_notification.xml

This is Your activity.

public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                int id = item.getItemId();
                switch (id){
                    case R.id.Fragment_one:
                        fragment = new HomeFragment();
                        break;
                    case R.id.Fragment_two:
                        fragment = new DashboardFragment();
                        break;
                    case R.id.Fragment_three:
                        fragment = new NotificationFragment();
                        break;
                }
                final FragmentTransaction transaction = fragmentManager.beginTransaction();
                transaction.replace(R.id.main_container, fragment).commit();
                return true;
            }
        });
