调用recyclerViewAdapter.notifyItemChanged()后调用onBindViewHolder时如何添加监听？

Question

I have a requirement where I want to set the state of an object after calling notifyItemChanged so that that change is reflected when view is updated next time . However, if I do this -

adapter.notifyItemChanged(itemPosition)
itemList[itemPosition].someValue = true

then onBindViewHolder gets called with someValue = true since onBindViewHolder is called after some time after calling notifyItemChanged. So, is there some way of knowing when onBindViewHolder has been called after calling notifyItemChanged after which I can set the desired value?

I tried locationsRecyclerView.adapter?.registerAdapterDataObserver(RecyclerView.AdapterDataObserver) but unfortunately, onItemRangeChanged is called much before onBindViewHolder .

if I understand you correctly you want to change the value of an object the next time after the item in the recycle view already changed then you can add a counter to the item and when counter is uqual 2 do something like that

    override fun onBindViewHolder(holder: CustomViewHolder, position: Int) {
        holder.bindViewHolder(position)
        holder.counter++

        if(holder.someValue==true&&counter==2){
            //do something

        }
    }
