inflate（）
返回XML视图层次结构的根布局。假设根视图具有id
rowbackground
，则此行

holder.rw.setTag(menuLinkList.get(position).getId());
用
字符串覆盖viewholder标记，循环使用视图将不起作用您可以将id等附加数据存储在视图持有者字段中，而无需将其放在视图标记中。为什么您甚至需要视图持有者。您可以直接获取对TextView、ImageView或任何其他视图的引用。请查看此代码以供参考。无需创建视图rowView。您可以直接使用convertView以便我在holder静态类ViewHolder{public TextView title；public ImageView image；public RelativeLayout rw；public String id；} 中创建一个新字段id，并像这样初始化它holder.id=menuLinkList.get（position）.getId（）现在我如何从我的活动中访问它？获取标签，转换到持有者，读取字段。也许有更好的办法来解决你的问题；这主要是为了消除类强制转换异常。如果这是正确答案，请将答案标记为正确答案。 holder.rw.setTag(menuLinkList.get(position).getId());
