How it works…

Anko hides all the complexity and gives you an easy-to-use function to achieve complex things. Let's check out the implementation of the selector function:

fun Context.selector(        title: CharSequence? = null,        items: List<CharSequence>,        onClick: (DialogInterface, Int) -> Unit) {    with(AndroidAlertBuilder(this)) {        if (title != null) {            this.title = title        }        items(items, onClick)        show()    }}

As you can see, beneath the surface, it's just like the old way, but Anko provides syntactic sugar, which helps us achieve the same thing with less code.
