See my comments inline that should give you a better description and slightly more information. Thank you.

I'm making the mistake of hoping people identify the problem based on not very much information, partially because I'm lazy, I guess. > > > However, when 0 is updated, 5 mirrors its data on the screen > > briefly > > What, exactly, is "its" in the phrase "5 mirrors its data"? Row 0 in the ListView contains an ImageView. Initially, all rows have a placeholder image. The thread updates row 0's ImageView, and I see the image updated on the screen. A split-second later, row 5's image is the same as row 0. So now, 0 has the new image, 1-4 still have the placeholder, and 5 shows the image associated with row 0. Then row 1's image is updated, and row 4 shows the same image. Then row 2 is updated with its image, (*screenshot linked below occurs here*) but 3 is next to load so it doesn't mirror row 2. So row 3 loads correctly, then row 4 reloads with the right image, then row 5 reloads. Here is a link to a screenshot (with some client-specific info cropped) that shows the ListView and the images in question at the state described: http://picasaweb.google.com/lh/photo/QMVbTulUnXWwwXdhCBPEUw?feat=directlink > > Basically, I cannot parse your sentence, and so I have no idea what > behavior you are seeing. > > > How many views are created by default for an adapter? > > From the standpoint of the adapter, 0, since adapters do not create rows > unless asked. > > From the standpoint of the ListView (and you never indicated in your > email exactly what selection widget you're using; I'm just guessing), it > will create as many rows as is needed.
