I've used droid-fu (http://github.com/kaeppler/droid-fu/) for exactly what you're describing, specifically the ImageLoader class within a custom adapter. Whenever the ListView calls getView on the adapter, you instantiate an ImageLoader, passing the ImageView that you want to populate with your web image and the intended position in the ListView as arguments. droid-fu also has a WebImageView which looks like it has some recent changes that will allow it to be used as a drop-in replacement for ImageViews within ListViews, so you may be able to use it and not even fool with a custom adapter at all. -Aaron -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
