Android 如何使用firebaseDatabase在TableLayout中实现recyclerView？

碎片类

        public class BlankFragment extends Fragment {
               //FragmentClass constructor with no parameter
              public BlankFragment() {
              // Required empty public constructor
              }

             @Override
             public void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);

             }


             **Inflating recyclerView with Dummy data i want to load data from firebase here


             @Override
             public View onCreateView(LayoutInflater inflater, ViewGroup container,
              Bundle savedInstanceState) {
              // Inflate the layout for this fragment


              View rootView = inflater.inflate(R.layout.fragment_blank, container, false);
                //FInding recyclerViewByid
              RecyclerView rv = (RecyclerView) rootView.findViewById(R.id.rv_recycler_view);
              rv.setHasFixedSize(true);
              // i have added dummy data into adapter but want toadd data from firebaseDatabase into Myadapter

              MyAdapter adapter = new MyAdapter(new String[] {
               "test one",  // i have hardcoded these data 
               "test two",  // but i want data from firebase to go here
