I am trying to get child view by position. I could get view when one item is clicked:
rvSellRecords.addOnItemTouchListener(new RecyclerItemClickListener(
I wouldn't recommend tracking the view list yourself. It could lead to weird issues with item updates, position updates, etc.
Instead on your SellRecordChangedEvent, use findViewHolderForAdapterPosition() instead of adapter.getView().
@Subscribe
public void onEvent(SellRecordChangedEvent event){
sell.getSellRecords().set(event.getSellRecordPosition(), event.getSellRecord());
sell.recalculate();
int position = event.getSellRecordPosition();
View view = yourrecyclerview.findViewHolderForAdapterPosition(position);
bus.post(new TransactionTitleChangedEvent(null, view));
}

And as a side note, it's better to implement an actual item click listener to the itemView on the ViewHolder instead of using touch listener. There's lots of examples of this online.
