FirebaseUI RecyclerAdapterを使用中にNoSuchMethodExceptionが発生しました

Question

FirebaseUIおよびそのrecyclerAdapterを使用して、次のJSON構造をrecyclerViewに表示しようとしています。

私は推測Firebaseチームによって行われた（ここでは、そこに自分自身の変化を伴う）の例を、以下、ここで見つけていますFirebase Quickstart - Databaseは

JSON Firebaseは、構造：

{ 
    "restaurants": { 
     "pushID": { 
      "name": "string", 
      "address": "string", 
      "times": "string", 
      "logo": "string", 
      "phone": "string", 
      "email": "string", 
      "order": "true", //Boolean 
      "booking": "true", 
      "delivery": "false" 
     }, 
     ... 
    } 
} 

私はすでに見てきましたここと他のサイト、すなわちGitHubに "NoSuchMethodException"を受け取ることに関する現在の投稿。

一般的な答えは、このための2つの考えられる原因があることのようだ：

1）あなたのviewHolderクラスが公開されていることを確認してくださいあなたのTaskViewHolderは、例えばの内部クラスであれば

2）あなたの活動は、静的であることを確認してください。

ここに関連コードがあります。

モデル：

@IgnoreExtraProperties 
public class Restaurant { 

    public String name, address, 
      time, logo, phone; 
    public String uid; 
    public int favoriteCount = 0; 
    public Map<String, Boolean> favorites = new HashMap<>(); 

    public Restaurant(){ 
     // Default constructor required for calls to DataSnapshot.getValue(Restaurant.class) 
    } 

    public Restaurant(String name, String address, String time, 
          String logo, String phone, String uid){ 
     this.name = name; 
     this.address = address; 
     this.time = time; 
     this.logo = logo; 
     this.phone = phone; 
     this.uid = uid; 
    } 

    @Exclude 
    public Map<String, Object> toMap() { 
     HashMap<String, Object> result = new HashMap<>(); 
     result.put("uid", uid); 
     result.put("name", name); 
     result.put("time", time); 
     result.put("logo", logo); 
     result.put("favoriteCount", favoriteCount); 
     result.put("favorites", favorites); 

     return result; 
    } 
} 

マイviewHolderクラス（別のクラスであるための必要がない "静的"）。

EllipsisUtil.classは、テキストビューを1行に制限したまま使用する方法です。何もない。

public class RestaurantViewHolder extends RecyclerView.ViewHolder { 

public TextView restaurantName, restaurantAddress; //tvDate, tvTime, tvPeople; 
public ImageView restaurantImageLogo, restaurantFavorite; 
private final Activity activity; 
private Locale locale = Locale.US; 
//private SimpleDateFormat dateFormat = new SimpleDateFormat("EEEE, MMMM dd yyyy", locale); 

public RestaurantViewHolder(Activity activity, View itemView){ 
    super(itemView); 
    this.activity = activity; 
    restaurantName = (TextView) itemView.findViewById(R.id.resName); 
    restaurantAddress = (TextView) itemView.findViewById(R.id.resAddress); 
    restaurantImageLogo = (ImageView) itemView.findViewById(R.id.RestaurantLogo); 
    restaurantFavorite = (ImageButton) itemView.findViewById(R.id.rFavorite); 
    //additional views for bookings activity 
    /* 
    tvDate = (TextView) itemView.findViewById(R.id.bookingDate); 
    tvTime = (TextView) itemView.findViewById(R.id.bookingTime); 
    tvPeople = (TextView) itemView.findViewById(R.id.numberPeople); 
    */ 
} 


public void bindToRestaurant(Restaurant restaurant, View.OnClickListener favoriteClickListener) { 
    //final int peopleNum = Integer.parseInt(restaurantInfo.booking_people); 
    restaurantName.setText(restaurant.name); 
    singleLineText(restaurantName); 
    restaurantAddress.setText(restaurant.address); 
    singleLineText(restaurantAddress); 
    restaurantFavorite.setOnClickListener(favoriteClickListener); 
    // Create a storage reference from our app 
    String dirName = "restaurantLogos/"; 
    String bucketUrl = "myFirebaseURL/"; 
    // Initialize Storage 
    StorageReference mStorageRef = FirebaseStorage.getInstance().getReference(); 
    StorageReference storageRef = mStorageRef.getStorage(). 
      getReferenceFromUrl(bucketUrl+dirName+restaurant.logo+".png"); 
    String logoUrl = storageRef.getDownloadUrl().toString(); 
    Glide.with(activity).load(logoUrl).into(restaurantImageLogo); 
    //additional views for bookings activity 
    /* 
    tvDate.setText(dateFormat.format(restaurantInfo.booking_date)); 
    tvTime.setText(restaurantInfo.booking_time); 
    String people; 
    if (peopleNum > 1){ 
     people = restaurantInfo.booking_people+" people"; 
    }else{ 
     people = restaurantInfo.booking_people+" person"; 
    } 
    tvPeople.setText(people); 
    */ 
} 

public void singleLineText(TextView textView){ 
    EllipsisUtil ellipsisUtil = new EllipsisUtil(textView); 
    ellipsisUtil.singleLineText(); 
} 
}

Answer 1

レストランのクラスが間違っているようです。

分野で

public class Restaurant { 
    public PushID pushId; 

    //Constructor 

    //getter and setters for PushId 
    public void setPushId(PushId pushId) { 
     this.pushId = pushId; 
    } 

    public PushId getPushId() { 
     return pushId; 
    } 
} 

PushIdクラスこの

public class PushId { 

    public String name, address, 
      time, logo, phone; 
    public String uid; 
    public int favoriteCount = 0; 
    public Map<String, Boolean> favorites = new HashMap<>(); 

    public Restaurant() { 
    } 

    public Restaurant(String name, String address, String time, 
         String logo, String phone, String uid) { 
     this.name = name; 
     this.address = address; 
     this.time = time; 
     this.logo = logo; 
     this.phone = phone; 
     this.uid = uid; 
    } 

    @Exclude 
    public Map<String, Object> toMap() { 
     HashMap<String, Object> result = new HashMap<>(); 
     result.put("uid", uid); 
     result.put("name", name); 
     result.put("time", time); 
     result.put("logo", logo); 
     result.put("favoriteCount", favoriteCount); 
     result.put("favorites", favorites); 

     return result; 
    } 

使用のようにする必要がありますフィールド

： あなたは

レストランクラスは、このようにする必要があり、完全なJSONを提供してくださいする必要があります

交換するだけです

compile 'com.firebaseui:firebase-ui-database:1.0.0' 

0123アプリレベルのbuild.gradleファイル内

compile 'com.firebaseui:firebase-ui-database:1.0.1' 

から

。

1.0.1 FirebaseUIバージョンが必要なFirebase/Play Servicesバージョン10.0.1を使用しています。これはあなたの問題を解決します。

> FirebaseUI Version Firebase/Play Services Version 
> 1.0.1    10.0.0 or 10.0.1 
> 1.0.0    9.8.0 
> 0.6.2    9.8.0 
> 0.6.1    9.6.1 
> 0.6.0    9.6.0 
> 0.5.3    9.4.0 
> 0.4.4    9.4.0 
> 0.4.3    9.2.1 
> 0.4.2    9.2.0 
> 0.4.1    9.0.2 
> 0.4.0    9.0.0
