I have used the technique, but not in code I'm allowed to share. I do need to more formally write this up at some point, but I do not have anything immediately handy. The gist of it is that you create your adapter and set it up, in getView() or newView()/bindView() (depending on adapter choice), to see if the thumbnail has been downloaded. If so, use it for the list row being inflated/updated; if not, leave the ImageView in the row pointing to some placeholder Drawable resource. This means as the user scrolls, she will pick up the thumbnails. Also, at the end, you can quickly iterate over the rows (ListView is a ViewGroup, IIRC, so there are methods to iterate its children) and ensure each of those rows' ImageViews are using their associated thumbnails. -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
