SwipeRefreshLayout обновляющий список RecyclerView c БД на PhpMyAdmin

Поместил RecyclerView в SwipeRefreshLayout, но не знаю как правильно написать в Javaфайле команду, чтобы при свайпе вверх, список обновлялся, то есть, на PhpMyAdmin в БД я изменил какую-нибудь надпись, чтобы эта надпись обновилась у меня в приложении, нужно полностью пере зайти в приложение. Мне нужно чтобы если я поменял данные в БД, простым свайпом мог обновить список в RecyclerView.

public class MainActivity extends AppCompatActivity{
    List<ItemSkatingRinkSchedule_2> mSkatingRinkScheduleList;
    RecyclerView recyclerView;

    RecyclerView.LayoutManager recyclerViewlayoutManager;
    RecyclerView.Adapter recyclerViewadapter;
    String HTTP_JSON_URL = "http://qqqqqqqqq.mcdir.ru/Subjects.php";
    String GET_JSON_FROM_SERVER_NUMBER = "session_number";
    String GET_JSON_FROM_SERVER_START = "session_start";
    String GET_JSON_FROM_SERVER_END = "session_end";
    String GET_JSON_FROM_SERVER_WEEKDAYS = "weekdays";
    String GET_JSON_FROM_SERVER_WEEKDAYS_AND_HOLIDAYS = "weekends_and_holidays";
    JsonArrayRequest jsonArrayRequest;
    RequestQueue requestQueue;
    View ChildView;
    int GetItemPosition;
    ArrayList<String> SubjectNames;
