RecyclerView上單擊刪除項目它

Question

我想，當點擊刪除項目但是它刪除一次，然後我得到了一個錯誤：

ERROR

Process: com.example.cardgame, PID: 3345 
        java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid item position 10(offset:10).state:11 

CODE

public class HandViewAdapter extends RecyclerView.Adapter<HandViewAdapter.ViewHolder>{ 
    private ArrayList<Card> cards; 
    private Context context; 

public HandViewAdapter(ArrayList<Card> cards, Context context) { 
    this.cards = cards; 
    this.context = context; 
} 

@Override 
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    LayoutInflater inflater = LayoutInflater.from(parent.getContext()); 

    View cardView = inflater.inflate(R.layout.card, parent, false); 

    return new ViewHolder(cardView); 
} 

@Override 
public void onBindViewHolder(ViewHolder holder, final int position) { 
    Card card = this.cards.get(position); 

    if (position == 0) { 
     card.setStatus(CardStatus.down); 
    } else { 
     card.setStatus(CardStatus.up); 
    } 

// Here i put the listener since i have tried other methods but i have no success to run them 
    holder.cardLayoutView.getCardView().setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      remove(position); 
     } 
    }); 
} 

@Override 
public int getItemCount() { 
    return this.cards.size(); 
} 

public Card remove(int index) { 
    cards.remove(index); 
    notifyItemChanged(index); 
    notifyItemRangeChanged(index, cards.size()); 
    return null; 
} 

public static class ViewHolder extends RecyclerView.ViewHolder implements CardBehavior { 
    public CardLayoutView cardLayoutView; 

    public ViewHolder(View view) { 
     super(view); 
     this.cardLayoutView = new CardLayoutView(view); 

    } 

    @Override 
    public void faceDown() { 
     this.cardLayoutView.faceDown(); 
    } 

    @Override 
    public void faceUp(Card card, Context context) { 
     this.cardLayoutView.faceUp(card, context); 
    } 
} 

}

據我所知，它刪除第一個項目後不更新位置，它應該更新他們對嗎？但它不，我如何解決它？我將不勝感激任何幫助，謝謝！

使用notifyItemRemoved

notifyItemRemoved(index) 

Notify any registered observers that the item previously located at position has been removed from the data set. The items previously located at and after position may now be found at oldPosition - 1.

然後

notifyItemRangeChanged(index, cards.size());
