单击它时，RecyClerview删除项目

Question

我在单击时试图删除项目，但它会删除一次，然后我得到一个错误：

错误

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

代码

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);
    }
}

}

我知道它在删除第一个项目后不会更新位置，应该对其进行更新吗？但这不是，我该如何解决？感谢任何帮助，谢谢！

Answer 1

使用notifyitemrever

notifyItemRemoved(index)

通知任何注册的观察者，先前位于位置的项目已从数据集中删除。现在可以在OldPosition -1。

上找到以前位于位置和之后的项目。

，然后

notifyItemRangeChanged(index, cards.size());
