android - 添加的 View 将 RecyclerView 作为父 View ，但 View 不是真正的 subview

Question

当 RecyclerView 的内容发生更改时，有时会出现问题。我有过滤 RecyclerView 数据的搜索 View 。过滤后我调用 notifyDataSetChanged();

我使用this作为适配器。

我认为该问题与添加页脚有关，但删除页脚后问题仍然出现，但不那么频繁

异常(exception):

java.lang.IllegalStateException: Added View has RecyclerView as parent but view is not a real child. Unfiltered index:0

我遇到了同样的问题...我通过使用 中的 Context 膨胀 ViewHolder 的 View 解决了这个问题parent.getContext()，并在调用 inflate 时指定 false:

final override fun onCreateViewHolder(parent:ViewGroup,viewType:Int):RecyclerView.ViewHolder
{
    View view = LayoutInflater.from(parent.getContext())
        .inflate(R.layout.listitem,parent,false);
    return new RecyclerView.ViewHolder(view) {};
}
