Код SettingsFragment

public class SettingsActivityFragment extends Fragment {
    public static Fragment newInstance(Context context) {
        SettingsActivityFragment f = new SettingsActivityFragment();
        return f;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_settings, container, false);

        return rootView;
    }
}

Собственно при клике на меню настроек, должен поменяться фрагмент. но происходит наложение двух фрагментов. Как исправить?
