Thanks, your blog posts are very helpful on constructing more elaborate lists. I'm still in the dark, however, about fetching images - they're .png files fetched via URL and I plan to cache them. I could put them on the SD card, or in the database. They are, hopefully, thumbnails of the appropriate size, but I may need to shrink them 10% or so. Is there a standard paradigm for doing this? All the image manipulation code I've seen so far refers to images already on the platform, e.g., R.drawable.image3, but I've seen nothing about converting a data stream into an icon.
