add the data of the adapter later, the position of the item is bottom

[sikeeoh]

I have not already added the item status

add item

add item code

view1.setOnClickListener {
            adapter.clickedItems.clear()
            adapter.notifyDataSetChanged()
            for (i in 1..100) {
                adapter.clickedItems.add("hi")
            }
        adapter.notifyDataSetChanged()}
}

However, scrolling return the item to its normal position.
