java - RecyclerView 点击删除项目

Question

我试图在单击时删除一个项目，但是它删除了一次，然后出现错误:

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);
    }
}

}

我知道删除第一项后它不会更新位置，它应该更新它们，对吗？但它没有，我该如何修复它？我将不胜感激任何帮助，谢谢!

Answer 1

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.

然后

notifyItemRangeChanged(index, cards.size());
