Когда я обновляю список recyclerview во фрагменте, заголовок раздела не отображается. Что мне делать? Я проверил адаптер recyclerview, он работает нормально, проблема может быть во фрагменте.Возможно, фрагмент не знает, куда поместить представление при обновлении фрагмента.

Может ли кто-нибудь, пожалуйста, помочь мне с этим

Вот мой фрагмент кода

    ButterKnife.bind(this, mRootView);
    GlowShipApplication.getAppComponent().inject(this);
    mLeadListPresenter.setView(this);
    mSysPrefs = SystemAppPreferences.getInstance(getActivity());
    mProgressBarHandler = new ProgressBarHandler(getActivity());


    if (getArguments() != null) {
        mData = getArguments().getString("fragmentName");

    }


    return mRootView;
}


@Override

    super.onResume();
