Android Searchview According to Firebase

Question

I want to implement the Android search function in a list fragment filled with data from the Firebase database.

Code for retrieving Firebase data

 mPOIAdapter = new FirebaseListAdapter<Poi>(
            getActivity(),
            Poi.class,
            R.layout.item_layout_poi,
            FirebaseDatabase.getInstance().getReference("poi").orderByChild("name")) {
        @Override
        protected void populateView(View v, Poi model, int position) {
            TextView pointsText = (TextView) v.findViewById(R.id.poi_textview);
            pointsText.setText(model.getName());
            TextView pointDescr = (TextView) v.findViewById(R.id.poi_building);
            pointDescr.setText(model.getDescription());
        }
    };

    mPOIListView.setAdapter(mPOIAdapter);

Search Code:

   @Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {

    inflater.inflate(R.menu.options_menu,menu);
    MenuItem item = menu.findItem(R.id.search);
    item.setVisible(true);
    SearchView searchView =  (SearchView) item.getActionView();

    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String s) {
            return false;
        }

        @Override
        public boolean onQueryTextChange(String s) {
            return false;
        }
    });
}

I want to use code like this to filter Listview items based on user input

searchView.setOnQueryTextListener(new OnQueryTextListener() {

    @Override
    public boolean onQueryTextSubmit(String s) {
        return false;
    }

    @Override
    public boolean onQueryTextChange(String s) {
        getListAdapter().getFilter().filter(s);
        return true;
    }
});

Since the FirebaseListAdapter does not have the same capabilities as the ListAdapter, I cannot use getListAdapter().getFilter().filter(s)

Is there an alternative way to use the search function in a Listview snippet filled with Firebase data

, "firebaseUserSearch" RecyclerView . databaseReference .

FB:

 BLABLA:
     Bars:
         01: 
            BarName: "Best bar"
         02:
            BarName: "The Worst bar"

:

  ....

    databaseReference = FirebaseDatabase.getInstance().getReference ("Bars");

  .....


  searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String searchText) {

            // TODO Auto-generated method stub

            return false;
        }

        @Override
        public boolean onQueryTextChange(String searchText) {

            searchText = searchView.getQuery().toString();

            firebaseUserSearch (searchText);

            return true;
        }
    });
    return true;
}



private void firebaseUserSearch (final String searchText) {


    firebaseRecyclerAdapter = new FirebaseRecyclerAdapter <Bar, ViewHolder>(

            Bar.class,
            R.layout.custom_row,
            ViewHolder.class,
       databaseReference.orderByChild("barName").startAt(searchText.toUpperCase()).endAt(searchText + "\uf8ff"))
    {
        @Override
        protected void populateViewHolder(ViewHolder viewHolder, Bar model, final int position) {

  ....
