适配器FireStore中的ProgressDialog

Question

问题：

我有一个屏幕，显示某个用户的日程安排。

但与此同时，我需要检查是否已经占用了任何时间表，并将背景颜色设置为较暗的颜色。

打印1：带有计划的RecyclerView屏幕。

打印2：它是相同的屏幕，但在检查可用的时间表后。

注意：如果我们在Wi-Fi网络上，充电速度很快，但如果是移动互联网，则速度非常慢。

我需要一些方法，在我的适配器中添加一个ProgressDialog，正好在检查时间表的那一刻。

在这里：

/*Checar Horario disponivel*/
            final FirebaseFirestore mDB = FirebaseFirestore.getInstance();
            CollectionReference mDBHorarios = mDB.collection("Empresas").document(empresa).collection("Agendamentos");

            mDBHorarios.whereEqualTo("profissional_id", ref.getId_Prof()).whereEqualTo("agenda_hora", ref.getHora())
                    .get()
                    .addOnCompleteListener(new OnCompleteListener<QuerySnapshot>() {
                        @Override
                        public void onComplete(@NonNull Task<QuerySnapshot> task) {
                            if (task.isSuccessful()) {
                                for (DocumentSnapshot document : task.getResult()) {

                                    Agendamentos doc = document.toObject(Agendamentos.class);

                                    String horaAgenda = doc.getAgenda_hora();
                                    /*Cor do fundo*/
                                    if ( horaAgenda.equals(ref.getHora()) ){

                                        fundoHora.setBackgroundColor(Color.parseColor("#E0E0E0"));
                                        statusHoraAgenda = true;


                                    }

                                }
                            } else {

                            }
                        }
                    });

注意：这可能不是一个好方法。我接受建议，如果有更好的方法在RecyclerView中执行此查询。
