如果不亲自修改 picasso 库，您就无法做到这一点。幸运的是，有一种常用且易于实现的解决方法。只需使用项目的 ID/位置标记可点击元素即可。例如(如果holder.itemImage是可点击的)，在onBindViewHolder()中:

holder.itemImage.setTag(position);

然后，在 onClick() 或任何处理点击的地方:

int position = (int) v.getTag();
String iconUrl = adapter.itemsList.get(position).geticon(); // make itemsList public or provide getter first
