Java 找不到符号方法setItemClickListener

“我正在尝试使Cardview在打开新活动时可单击，但在调用setitemclcik listener时，我迷失了方向。它为匿名itemclicklistener提供了错误代码。”

错误的方法

 Viewholder.setItemClickListener(new ItemClickListener() {
            @Override
            public void onItemClick(int pos) {
                ......
            }
        });

正确的方法

您的视图持有者持有XML属性。您应该调用RootLayout对象

Viewholder.Your_root_layout_OBJ.setItemClickListener(new ItemClickListener() {
            @Override
            public void onItemClick(int pos) {
                ......
            }
        });

---

您的代码有多个问题： 1） 不要以这种方式调用ViewHolder的字段。您需要从onBindViewHolder方法中的holder参数强制转换它

YourViewHolderClass yourViewHolderMember=（YourViewHolderClass） 持有人

2） 您的ViewHolder类没有方法setItemClickListener。但它的根元素字段名为itemView。试着这样做：

yourViewHolderMember.itemView.setOnClickListener（）

请你解释一下“放置你的对象”这一行，年份和季度的值是int

Viewholder.ImageTitleNameView.

表示你有一个文本视图，它位于Viewholder下。这样，你可以调用你的父布局ID。你解决问题了吗。现在被困在另一个地方。我用错了布局。现在已经解决了，但是现在陷入了空异常。告诉我们在哪里？？？先生，我从哪里得到这个根布局object@HarisDurrani看看我的答案：）@HarisDurrani open

newsletter\u recyclerview\u items.xml

。在Viewholder部分调用顶部布局。
