如何在itemClickListener中更改自定义row_item中的图像？

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<DataItem> mDataList;
    private OnItemClickListener mListener;

    // 构造函数和其他方法

    public interface OnItemClickListener {
        void onItemClick(int position);
    }

    public void setOnItemClickListener(OnItemClickListener listener) {
        mListener = listener;
    }

    // ViewHolder类和其他方法

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        // 设置图像
        holder.imageView.setImageResource(mDataList.get(position).getImageResource());

        // 设置item点击事件
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (mListener != null) {
                    mListener.onItemClick(position);
                }
            }
        });
    }
}

public class MainActivity extends AppCompatActivity {
    private MyAdapter mAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 初始化适配器和RecyclerView

        mAdapter.setOnItemClickListener(new MyAdapter.OnItemClickListener() {
            @Override
            public void onItemClick(int position) {
                // 根据position获取对应的数据项
                DataItem item = mAdapter.getDataList().get(position);

                // 更改图像
                item.setImageResource(R.drawable.new_image);

                // 更新适配器
                mAdapter.notifyItemChanged(position);
            }
        });
    }
}
