firestore recycler adapter не получает никаких данных. Я ловлю ошибку, указанную выше. Я искал, но никто не дал аккуратный ответ.
- Я использую EditText и кнопку Image для поиска.
- Я использую аутентификацию, поэтому не буду, если это повлияет на мой
recycleradapter.
- Правила firebase установлены на: read, write if: request.auth! = Null
так как у меня есть аутентификация.
Вот код:

Обновление
Спасибо за вашу помощь. Я исправил нулевую проблему. Другая проблема в том, что я не получаю никаких результатов в своем обзоре утилит.
Это проблема пользовательского интерфейса firestore ????;
Вот класс, который получает информацию из Firebase:
public class Pharmacien {
private String AdressePH,NomSiege,ImageURL;
private static String Type;
private Double Rating;
private GeoPoint Position;
public Pharmacien(String AdressePH, String NomSiege, String ImageURL, Double Rating, GeoPoint Position, String Type) {
this.AdressePH = AdressePH;
this.ImageURL = ImageURL;
this.NomSiege = NomSiege;
this.Position = Position;
this.Rating = Rating;
this.Type=Type;
}
public Pharmacien() {
}
public String getAdressePH() {
return AdressePH;
}
public void setAdressePH(String adressePH) {
AdressePH = adressePH;
}
public String getNomSiege() {
return NomSiege;
}
public void setNomSiege(String nomSiege) {
NomSiege = nomSiege;
}
public String getImageURL() {
return ImageURL;
}
public void setImageURL(String imageURL) {
ImageURL = imageURL;
}
public static String getType() {
return Type;
}
public Double getRating() {
return Rating;
}
public void setRating(Double ratingGlobal) {
Rating = ratingGlobal;
}
public GeoPoint getPosition() {
return Position;
}
public void setPosition(GeoPoint position) {
Position = position;
}
}
Решение
-_- менеджер макета было достаточно
Для всех, у кого была эта проблема
pharmacienlist.setHasFixedSize(true);
pharmacienlist.setLayoutManager(new LinearLayoutManager(this));
