Check this video about ListView Google IO 2010 - World of ListView

I think this is not possible. And you have something wrong in your app design. Please give more details, on why you do not wont your ListView items to be refreshed while scrolling.

Answer 2

When ListView is scrolled, it uses ListAdapter to show new items. Each time new item becomes visible, ListView asks adapter to refresh this item's view. Also ListView may cache some items' views for performance reasons.

I'm not sure what exactly you want to achieve, but you can't disable ListView refreshing. That's basically one of the reason ListView was implemented in the first place: smart refreshing.

You should describe what you want to achieve, I've got feeling that it's not related with ListView refreshing itself.

You can use Pull To Refresh
