First you have to realize that the list-item you want to find may not be visible. This means that using getChildAt on the list-view won't always work. But, if the list-item becomes visible later on, you need to make sure it'll reflect the change you made earlier for that item.
I think that the simplest way of doing this is, again, modifying the appropriate element stored in the adapter and then calling notifyDataSetChanged() on the adapter. Then in the Adapter's getView(...) method, which will be called for each visible elements in your list-view, you do the thing you need to do. In your implementation of getView(...) you may be able to detect if the list-item actually changed (e.g. use getTag() on the list-item- view). If not, just return the view provided to you by the getView (...) method, otherwise update this view with the changed data.
