android recyclerview的行项目视图在recyclerview的滚动条上隐藏/显示出错

我正在使用RecyclerView显示我的应用程序中的产品列表,我需要根据过道对产品进行分组。在列表中第一次获取数据时,产品按照通道正确分组。当我们滚动视图时,会为错误的项显示通道组分隔符,并且一旦onBindViewHolder被自动刷新,分隔符就会恢复到正确的位置。

MyAdapter.class
override fun onBindViewHolder(holder: ItemViewHolder, position: Int) { 
    itemsGrouping(pickItem, pickItemView, holder.adapterPosition)
}

private fun itemsGrouping(pickItem: PickItem, pickItemView: View, adapterPosition: Int) {
//Based on some condition
if(SomeCondition)
    itemDivider(pickItemView,true)
else 
    itemDivider(pickItemView,false)
}

private fun itemDivider(v: View, boolean: Boolean) {
    if(boolean) {
        v.visibility = View.VISIBLE
    } else {
        v.visibility = View.GONE
    }
 }
