As Kamac said, I don't think that's possible either (could be wrong.... I'm still a noob but learning), but.....
This may not be practical for very huge lists, but you could use the labels-in-a-scrollview sample in the link below instead of a listview. It would likely take a little modification and it wouldn't hold the name/value combo like a listview does but the values could be stored in a list though. At least the item chosen would stay highlighted which is what you are after.
