Empty List (Custom) - Android Studio

Hello, good afternoon

My Custom ListView is not displaying my real time data from Firebase, follow the code

public void gerarLotes() {

lotes = new ArrayList<>();

lotesReferencia.addChildEventListener(new ChildEventListener() {
    @Override
    public void onChildAdded (@NonNull DataSnapshot dataSnapshot, @Nullable String s){

        for(DataSnapshot postSnapshot : dataSnapshot.getChildren()){

            Lotes json = dataSnapshot.getValue(Lotes.class);

            HMAux aux = new HMAux();
            aux.put(HMAux.TEXTO_01, json.getId());
            aux.put(HMAux.TEXTO_02, json.getPecas());
            aux.put(HMAux.TEXTO_03, json.getPreço());

            lotes.add(aux);

        }

    }
