Question

我坚持使用groupie适配器，无法弄清楚我在这里出了什么问题。

问题1 适配器onclick侦听器仅在第二次单击时有效，

问题-2 当我尝试更新部分时，它会更新整个部分（包括其中没有任何更改的某些部分），从而更改其中的项目ID。以下是代码。

    class HeaderItem(val data: String) : Item<GroupieViewHolder>() {

            return R.layout.item_header
        }

        override fun bind(viewHolder: GroupieViewHolder, position: Int) {

        }

    }
    private val onItemClickListener = OnItemClickListener { item, _ ->
        if (item is listItem) {
            Toast.makeText(activity, "clicked ${item.id}", Toast.LENGTH_SHORT).show()
        }
    }

}

如果我第一次单击某个项目，则“ onItemCLickListener”不起作用，如果我第二次单击，则它仅起作用。每次更新一个项目时，整个部分都会刷新（我认为分组查看器使用diffUtil）

groupie recycleview适配器未正确更新
