Hi all, In the application im working on now i came up with the following problem. I have list view which is displaying items with images in most cases it will be different image for different items ( thumbnails about 60x60 pixels ). So the problem is how can i handle image processing for the view. For know i have the following variants: 1. I can cache all bitmaps and when i try to display view i get bitmap from cache synchronously and display it. The problem is that 60x60=3600x4=14kb per bitmap which is waste of resources. 2. When i need to display view i can register event to some thread to decode the associated bitmap which will decode it in background and than to update gui. This sounds good for me the scrolling is still smooth because all image processing is done in background. Updating list view is bit jerky for now i am doing it view notifyDataSetChanged which is updating all visible views although i can update thumbnail for a single item. So question one is is there better way the update single listview element than calling notifyDataSetChanged. Can you think of some better strategies for solving this problem. Thanks
