Я подключил свое приложение к Firestore, и у меня есть строка с именем timey, которая является датой, которая выбрана (не имеет значения, как) и сравнивается со строкой timey в документах Firestore.
Мне удалось заставить приложение отображать вывод Firestore на TextView, но если у меня есть 2 записи с одинаковой датой, оно всегда выбирает одну и забывает о другой. Поэтому я решил попробовать отобразить данные, используя FirebaseRecyclerAdapter, который обычно отображает «одну запись даты», но как только я выбираю дату с 2 записями, приложение вылетает. Вот исходный код, есть идеи, как заставить RecyclerView отображать десятки записей с одинаковой датой и размещать их внутри RecyclerView как отдельные записи?
...
passArg - дата, переданная из другого макета.
static String passedArg;
RecyclerView reserveList;
private static final CollectionReference reservationCollection = FirebaseFirestore.getInstance().collection("reservations");
private static Query reservationsQuery;
private FirebaseFirestore db;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_page);
textView = findViewById(R.id.textView);
textView2 = findViewById(R.id.textView2);
textView3 = findViewById(R.id.textView3);
passedArg = getIntent().getExtras().getString(MESSAGE_KEY);
textView.setText(passedArg);
reservationsQuery = reservationCollection.whereEqualTo("timey", passedArg);
RecyclerView reserveList = (RecyclerView) findViewById(R.id.reserveList);
reserveList.setLayoutManager(new LinearLayoutManager (this));
FirestoreRecyclerOptions<Reservations> options =
new FirestoreRecyclerOptions.Builder<Reservations>()
.setQuery(reservationsQuery, Reservations.class)
.setLifecycleOwner(this)
.build();
FirestoreRecyclerAdapter<Reservations, ReservationsHolder> adapter = new FirestoreRecyclerAdapter<Reservations, ReservationsHolder>(options) {
@Override
protected void onBindViewHolder(@NonNull ReservationsHolder holder, int position, @NonNull Reservations model) {
holder.setName(model.getName());
holder.setTime(model.getTime());
holder.setCountry(model.getCountry());
}
@NonNull
@Override
public ReservationsHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
return new ReservationsHolder(LayoutInflater.from(parent.getContext())
.inflate(R.layout.reservations, parent, false));
}
};
reserveList.setAdapter(adapter);
Если вам нужен дополнительный код, дайте мне знать.
