将一些xml属性添加到cardview后，ViewHolder ItemView clickListener无法正常工作

Question

ViewHolder itemView.OnClickListener（this）第一次完美运行，单击itemView时调用此方法 onListClick.onSectionListItemClick 。但是现在当我在cardview部分向ItemViewHolder布局中添加了一些这些属性时，itemView.OnClickListener（this）无效， onListClick.onSectionListItemClick（）方法未被调用。那有什么，我想念？请检查一下。

item_layout.xml
