Добавление ListView в Fragment

Есть несколько вкладок Fragment при использовании BottomNavigationView.

При добавлении ListView в xml фрагмента и начальной инициализации в onCreate, приложение закрывается с ошибкой "Attempt to invoke virtual method 'void android.widget.ListView.setAdapter(android.widget.ListAdapter)' on a null object reference"

        countriesList.setOnItemClickListener(itemListener);

    }

  /*  @Override
    public void onBackPressed() {
        super.onBackPressed();

}

Если добавлять ListView в activity_main.xml, а не в fragment_intents.xml приложение запускается и работает, но естественно ListView отображается при любой выбранной вкладке Fragment. Как добавить ListView в Fragment, чтобы данной ошибки не возникало?
