FirebaseRecyclerAdapter error：java.lang.Throwable：addInArray

Question

Stackoverflowでも同様の質問がありましたが、動作する回答はありませんでした。この問題を解決する方法を見つけることはできません。

私RecyclerViewはうまく動作しているようですが、それはゆっくりロードし、私はRecyclerView 4の項目について20回を繰り返し、このエラーを取得しています。

これは私のコードです：

DatabaseReference ref = FirebaseDatabase.getInstance().getReference(); 
LinearLayoutManager manager = new LinearLayoutManager(this); 
listRaces.setHasFixedSize(true); 
FirebaseRecyclerAdapter mAdapter = new FirebaseRecyclerAdapter<Race, ViewHolder>(Race.class, R.layout.races_row, ViewHolder.class, ref.child(Constant.FIREBASE_RACES).orderByChild("runners/" + User.getId()).equalTo(true).limitToFirst(4)) { 
    @Override 
    protected void populateViewHolder(ViewHolder viewHolder, Race race, int position) { 
     MyLog.log(String.valueOf(position)); 

     if(position<3) { 
      viewHolder.setDistance(String.valueOf(race.distance) + " Km"); 
      viewHolder.setLevels(String.valueOf(race.level_min) + " - " + String.valueOf(race.level_max)); 
      viewHolder.setRunners(String.valueOf(race.signed_runners) + "/" + String.valueOf(race.max_runners)); 
      viewHolder.setTime(TimeHandler.timestampToDate(String.valueOf(race.date))); 

     } else { 
      LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT); 
      viewHolder.textListDistance.setLayoutParams(layoutParams); 
      viewHolder.setDistance("Ver todas..."); 
      viewHolder.textListDistance.setTextSize(14f); 
      viewHolder.textListDistance.setGravity(Gravity.CENTER); 
      viewHolder.textListDistance.setTypeface(null, Typeface.ITALIC); 
     } 
    } 
}; 

listRaces.setAdapter(mAdapter); 
listRaces.setLayoutManager(manager); 

そして、これが私のViewHolderクラスです：

public static class ViewHolder extends RecyclerView.ViewHolder { 
    private final TextView textListDistance; 
    private final TextView textListLevels; 
    private final TextView textListRunners; 
    private final TextView textListTime; 

    public ViewHolder(View itemView) { 
     super(itemView); 
     textListDistance = (TextView) itemView.findViewById(R.id.textListDistance); 
     textListLevels = (TextView) itemView.findViewById(R.id.textListLevels); 
     textListRunners = (TextView) itemView.findViewById(R.id.textListRunners); 
     textListTime = (TextView) itemView.findViewById(R.id.textListTime); 
    } 

    public void setDistance(String distance) { 
     textListDistance.setText(distance); 
    } 
    public void setLevels(String levels) { 
     textListLevels.setText(levels); 
    } 
    public void setRunners(String runners) { 
     textListRunners.setText(runners); 
    } 
    public void setTime(String time) { 
     textListTime.setText(time); 
    } 
} 

私は本当に意志このための助けを感謝します。ありがとう。

EDIT：

であってもエラーが残るこの単純化されたコードで：

DatabaseReference ref = FirebaseDatabase.getInstance().getReference(); 
     LinearLayoutManager manager = new LinearLayoutManager(this); 
     listRaces.setLayoutManager(manager); 
     listRaces.setHasFixedSize(true); 
     FirebaseRecyclerAdapter mAdapter = new FirebaseRecyclerAdapter<Race, ViewHolder>(Race.class, R.layout.races_row, ViewHolder.class, ref.child(Constant.FIREBASE_RACES).orderByChild("runners/" + User.getId()).equalTo(true).limitToFirst(4)) { 
      @Override 
      protected void populateViewHolder(ViewHolder viewHolder, Race race, int position) { 
        viewHolder.setDistance(String.valueOf(race.distance) + " Km"); 
        viewHolder.setLevels(String.valueOf(race.level_min) + " - " + String.valueOf(race.level_max)); 
        viewHolder.setRunners(String.valueOf(race.signed_runners) + "/" + String.valueOf(race.max_runners)); 
        viewHolder.setTime(TimeHandler.timestampToDate(String.valueOf(race.date))); 
      } 
     }; 
     listRaces.setAdapter(mAdapter); 

ここに私のraces_rowレイアウト：

</LinearLayout> 

そしてここで、デバイス上でレンダリングRecyclerView：

RecyclerView

ありがとうございます。

Answer 1

まず、RecyclerViewのスクロールを遅くするpopulateViewHolder機能にLayoutParamsを設定しています。この目的のために異なるレイアウトを使用している場合や、可視性をGONEまたはに設定するだけで、同じレイアウトを使用できます。

基本的にレイアウトには4つのTextViewがあります。今度はこのようなレイアウトを設定してください。 ViewHolder

public static class ViewHolder extends RecyclerView.ViewHolder { 
    // ... Other textviews 
    private final TextView textListDistanceItalic; 

    public ViewHolder(View itemView) { 
     super(itemView); 

     // ... Initialize others 
     textListDistanceItalic = (TextView) itemView.findViewById(R.id.distance_italic); 
    } 

    // ... Other Setters 
    public void setItalicInvisible() { 
     textListDistanceItalic.setVisibility(View.GONE); 
    } 
    public void setItalicVisible() { 
     textListDistanceItalic.setVisibility(View.VISIBLE); 
    } 
} 

に余分TextViewを入れ

<LinearLayout ..> 
    <TextView 
     android:id="@+id/distance" ../> 

    <!-- Add an extra TextView here and set visibility=gone by default --> 
    <TextView 
     android:id="@+id/distance_italic" 
     android:visibility="gone" 
     android:gravity="center" ../> 

    <TextView 
     android:id="@+id/level" ../> 
    <TextView 
     android:id="@+id/runner" ../> 
    <TextView 
     android:id="@+id/time" ../> 
</LinearLayout> 

今、あなたのpopulateViewHolder機能では、これを持っていることがあります。

if(position < 3) { 
    // Call the setters 
    // ... 

    // Set the italic distance invisible 
    viewHolder.setItalicInvisible(); 

} else { 
    // Call the setters 
    // ... 

    // Set the italic distance visible 
    viewHolder.setItalicVisible(); 
}
