Re-order Query after click on Button - FirestoreRecyclerOptions

Currently, i can sort my documents in a Query, with it's:

query = anuncioRef.orderBy(campo, Query.Direction.DESCENDING).limit(100);
        options = new FirestoreRecyclerOptions.Builder<AnuncioPrincipal>().setQuery(query,
                AnuncioPrincipal.class).build();
        adapter = new AnuncioAdapter(options);
  RecyclerView recyclerView = root.findViewById(R.id.recyclerCadAnun);
        recyclerView.setLayoutManager(new LinearLayoutManager(context));
        recyclerView.setAdapter(adapter);

This works fine, but, i need that it change when the user click on button, i need that var "campo" must be changed to "dataPreco" and the list in recycler view must be updated: 

        botaoFiltrar.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                campo = "dataAnuncio";

            }
        });

In spite of "campo" be changed to "dataAnuncio", the recyclerView still remains equals.

I need that the button click, the recyclerView change to the new query orderBy() method.

The FirestoreRecyclerAdapter has an updateOptions method that you can call to update the options.

So you could call that with something like:

query = anuncioRef.orderBy(campo, Query.Direction.DESCENDING).limit(100); // new campo
options = new FirestoreRecyclerOptions.Builder<AnuncioPrincipal>().setQuery(query, AnuncioPrincipal.class).build();

adapter.updateOptions(options);
