【问题描述】：
问题：
我有一个屏幕显示某个用户的日程安排。
但与此同时，我需要检查是否有任何日程安排已被占用，并将背景颜色设置为较深的颜色。
打印 1：带有时间表的 RecyclerView 屏幕。
打印 2：它是相同的屏幕，但在检查可用的时间表之后。
注意：如果我们在 Wi-Fi 网络上，充电很快，但如果是移动互联网网络，则很慢。
我需要一些方法，在我的适配器中添加一个 ProgressDialog，恰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。如果有更好的方法在 RecyclerView 中执行此查询，我接受建议。
代码完整 - 适配器：
public class HorariosProfissionalAdapter extends FirestoreAdapter<HorariosProfissionalAdapter.ViewHolder>{
public interface OnHorariosProfissionaisListner {
void onHorarioProfissionaisSelected(DocumentSnapshot horariosProfissional);
}
private OnHorariosProfissionaisListner mListner;
public HorariosProfissionalAdapter(Query query, OnHorariosProfissionaisListner listner){
super(query);
mListner = listner;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
return new ViewHolder(inflater.inflate(R.layout.card_horarios_profissional, parent, false));
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.bind(getSnapshot(position), mListner);
}
static class ViewHolder extends RecyclerView.ViewHolder {
private Boolean statusHoraAgenda = false;
@BindView(R.id.tvHoraProf)
TextView hora;
@BindView(R.id.fundoHorario)
LinearLayout fundoHora;
public ViewHolder(View itemView) {
super(itemView);
ButterKnife.bind(this, itemView);
}
public void bind(final DocumentSnapshot snapshot,
final OnHorariosProfissionaisListner listener) {
final HorariosProfissionais ref = snapshot.toObject(HorariosProfissionais.class);
String empresa = ref.getId_Emp();
/*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 {
}
}
});
hora.setText(ref.getHora());
// Click listener
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (listener != null && !statusHoraAgenda) {
listener.onHorarioProfissionaisSelected(snapshot);
}
}
});
}
}
}
