Purge the queue that is filled by your background process. List item views (and imageviews within your list item views) are recycled. Remember for which list-item (or image-view) the background-thread is loading a bitmap (you'll know this in the adapter's getView method). Later, as soon as the same image-view is re-used for another bitmap, look-up the loading of the bitmap that was previously to be assigned to the image-view and remove this bitmap from the cache. For good measure, call 'recycle()' on it. Then start load the new bitmap for the recycled image-view.
Instead of immediately purging unused bitmap, you may want to hold on to them a little longer so that your background doesn't need to re-load the same image over and over again. However, this will increase the size of your queue. You'll have to put a limit on the queue (never more than 'x' bitmaps in the queue). Also be sure to load bitmaps that are at most slightly larger than your image-view (BitmapFactory.Options.inSampleSize > 1). Don't load full-sized bitmap if it's not absolutely necessary. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
