如何在recyclerView中显示两个不同项之间的不同项？

public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
    private static final int TYPE_ITEM1 = 1;
    private static final int TYPE_ITEM2 = 2;

    // 数据源
    private List<Object> dataList;

    public MyAdapter(List<Object> dataList) {
        this.dataList = dataList;
    }

    @Override
    public int getItemViewType(int position) {
        // 根据数据类型返回不同的类型值
        if (dataList.get(position) instanceof Item1) {
            return TYPE_ITEM1;
        } else if (dataList.get(position) instanceof Item2) {
            return TYPE_ITEM2;
        }
        return super.getItemViewType(position);
    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        // 根据类型值创建对应的ViewHolder
        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        if (viewType == TYPE_ITEM1) {
            View itemView = inflater.inflate(R.layout.item_type1, parent, false);
            return new Item1ViewHolder(itemView);
        } else if (viewType == TYPE_ITEM2) {
            View itemView = inflater.inflate(R.layout.item_type2, parent, false);
            return new Item2ViewHolder(itemView);
        }
        return null;
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        // 根据类型值选择使用对应的ViewHolder，并将数据绑定到ViewHolder上
        if (holder instanceof Item1ViewHolder) {
            Item1 item1 = (Item1) dataList.get(position);
            ((Item1ViewHolder) holder).bindData(item1);
        } else if (holder instanceof Item2ViewHolder) {
            Item2 item2 = (Item2) dataList.get(position);
            ((Item2ViewHolder) holder).bindData(item2);
        }
    }

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

    // ViewHolder类
    private static class Item1ViewHolder extends RecyclerView.ViewHolder {
        // 布局中的控件
        private TextView textView;

        public Item1ViewHolder(View itemView) {
            super(itemView);
            // 初始化控件
            textView = itemView.findViewById(R.id.text_view);
        }

        public void bindData(Item1 item1) {
            // 绑定数据
            textView.setText(item1.getText());
        }
    }

    private static class Item2ViewHolder extends RecyclerView.ViewHolder {
        private ImageView imageView;

        public Item2ViewHolder(View itemView) {
            super(itemView);
            imageView = itemView.findViewById(R.id.image_view);
        }

        public void bindData(Item2 item2) {
            // 绑定数据
            imageView.setImageResource(item2.getImageResId());
        }
    }
}

// 数据类型
class Item1 {
    private String text;

    public Item1(String text) {
        this.text = text;
    }

    public String getText() {
        return text;
    }
}

class Item2 {
    private int imageResId;

    public Item2(int imageResId) {
        this.imageResId = imageResId;
    }

    public int getImageResId() {
        return imageResId;
    }
}
