As you say, "this structure is kind of messy", and even the name for it may strike you as a little 'messy';) It is called an "anonymous class". You might want to look it up in the classic online tutorials originally created by Sun and now maintained by Oracle.
I found it messy too, and I still find the standard indentation of the anonymous class annoying. But I decided to learn to live with it because 1) it is extremely common, and that not just in Android Java 2) there is one big, good thing it does for us: it spares the reader from having to track down all references to the class to verify that it really is instantiated only in that one place. This really does simplify debugging. It also explains why it is heavily used in Swing and JavaFX as well as Android. In fact, that is pretty much what the above-mentioned tutorials says at http://docs.oracle.com/javase/tutorial/uiswing/events/generalrules.html#innerClasses.
