ListView recycles rows by calling getView(int position, View convertView, ViewGroup parent) in the ListAdapter. The convertView argument can be an existing view that will be moved to the new position. The ListAdapter will usually keep the convertView (instead of creating a new one) and modify it to display information for the new position. I am guessing that you are using a standard list adapter that doesn't know about your animations.
You could subclass the ListAdapter and override getView() to make sure than any animations are in the appropriate state when the view gets repurposed.
