You could use the ItemContainerGenerator, e.g:

var lvitem = listView.ItemContainerGenerator.ContainerFromItem(item) as ListViewItem;
var lvitem = listView.ItemContainerGenerator.ContainerFromIndex(0) as ListViewItem;

However by default the ListView is virtualizing, this means ListViewItems are created on the fly as needed (only if the item is actually visible in the list), so the above methods will not return containers for items which are currently not visible.

This being the case it usually is preferable to define a binding on the Background property via a Setter in the ItemContainerStyle.
