Recycler view not scrolling to the top after adding new item at the top, as changes to the list adapter has not yet occurred

Question

I am getting the new list with new item at the start in my live data and then using its data to update the adapter

viewModel.myLiveData.observe { this, Observer          


        

Answer 1

Use this way

viewModel.myLiveData.observe { this, Observer { myList -> 
    adapter.submitList(myList) // Assuming you are notifying adapter by notifydatasetchanged()
    recyclerView.post { recyclerView.scrollToPosition(0) }
}

Here post is giving UI Thread some time to populate Recycler with new data and then call scrollToPosition.
