java - 如何将对象从适配器发送到 Activity

Question

当我发送一些数据时，它给了我这个错误 java.lang.ArrayIndexOutOfBoundsException:长度=15；指数=-1 ，我不知道为什么。我试图搜索，但我没有找到与此错误相关的任何内容。
我的代码

   @NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(context).inflate(R.layout.book_items, parent, false);
    ViewHolder viewHolder = new ViewHolder(view);
    viewHolder.onClick.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(context, BookContentActivity.class);
            intent.putExtra("title",bookList.get(viewHolder.getAdapterPosition()).getTitle());
            intent.putExtra("author",bookList.get(viewHolder.getAdapterPosition()).getAuthor());
            intent.putExtra("details",bookList.get(viewHolder.getAdapterPosition()).getDetails());
            intent.putExtra("imageURL",bookList.get(viewHolder.getAdapterPosition()).getImgUrl());
            intent.putExtra("rating",bookList.get(viewHolder.getAdapterPosition()).getRating());
            intent.putExtra("pages",bookList.get(viewHolder.getAdapterPosition()).getPages());
            intent.putExtra("downloadUrl",bookList.get(viewHolder.getAdapterPosition()).getDownloadURL());

            context.startActivity(intent);
        }
    });
    return new ViewHolder(view);
}

@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {

    holder.title.setText(this.bookList.get(position).getTitle());
    holder.author.setText(this.bookList.get(position).getAuthor());
    Glide.with(holder.itemView.getContext())
            .load(this.bookList.get(position).getImgUrl())
            .transforms(new CenterCrop(),new RoundedCorners(16))
            .into(holder.imageBook);

    holder.bookRating.setRating(this.bookList.get(position).getRating());
    holder.pages.setText(this.bookList.get(position).getPages());
}

点击监听器应添加到您将 View 绑定(bind)到 ViewHolder 对象 (onBindViewHolder) 的位置。但是，为了获取该对象并启动您的下一个 Activity ，传递一个自定义监听器接口(interface)来获取单击的对象会更好。因为适配器不应该负责通过 Intent 启动 Activity 。
希望这会有所帮助。
