Cache the images in RAM once you load them, so you do not re-load them from the file when the user scrolls and then scrolls back. Maybe pre-load the images if you know what they are in advance and know for certain they will be used. You don't want to go overboard on this, lest you run out of memory. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android App Developer Books: http://commonsware.com/books.html --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
