We cannot ignore them — they are everywhere. Lists of things “todo”. Things to buy. Choices to choose from. No mobile environment would be complete without the ability to display a list of choices to a user. Of course, every platform has their own name for them. Android calls its list a ListView and requires an “adapter” to supply the data to the list widget. iPhone developers create lists with the UITableView and flesh out a “protocol” in Objective-C to provide the data via a callback paradigm. For the Java programmers among us, a protocol is similar to an Interface in Java.
