Best Site in the Multiverse

Sometimes we need to maintain the selected position in a list. This example was taken from a real-world, off-road application where users interact with the application in a bumpy environment and need a fool proof way of changing the sort order of items in a list. When an item is clicked in the list and that row becomes the selected row as indicated by a different background color. The user can then change the position of the selected row using the Move Up and Move Down buttons on the screen.

Here’s a screen-shot of this example running in the emulator.
