Can anyone tell me how to detect when a ListView quits scrolling?
And.. On a related note, how would I determine which of the ListView's items are showing once it does quit scrolling. For Background : I have a ListView that has from zero to 200 items in it. Each item has an ImageView and a TextView. The Text I'm filling in as it is received, but I don't want to download the image (they are small bitmaps) unless the user is looking at that particular item. I've worked out the background thread that will download the images I need, but I'm stuck on figuring out which images I need to download, and when :-). It would be nice if there was an OnScrollFinished event. but I can't find it ;). By the way, I did try just downloading the images in the GetView event, but it slows down the scrolling and makes it very jerky, so it is not a very good solution. I guess another option would be to just start the background thread and just start at the first item, and keep downloading all images and storing them in my data class until the GetView calls for them, but that seems like a waste of resources, and bandwidth because in general the most relevant items are at the top, and I don't expect the users to get all the way to the bottom of the list very often.
