ArrayList is list which holds list of int, String...

ArrayAdapter is adapter, which is used for Listing items in screen, like for ListView. It has more functions for that, if item removed in background, ArrayAdapter will remove it as well if you call adapter.notifyDatasetChanged(), it updates screen. You can not use ArrayList as adapter for Listing items on screen, but you can use it for holding list of items in memory.

Picture below ArrayAdapter holds items inside ListView. You can not use ArrayList for such listing.
