The short answer is that you should never access a single
ListView row and update it's
View (There are ways to do it by keeping a reference to the displayed views, but you shouldn't).
What you should do is:
notifyDataSetChanged()for that adapter.
There is no good reason not to follow this and update just one row (because if it takes too long to update the views, it means you are doing something wrong).
