Android: Difference between positive, negative, and neutral button

Question

Is there a functional difference between positive, negative, and neutral buttons, particularly in the context of AlertDialogs?

Answer 1

As stated earlier, it defines the order, and you can have only one button of each kind. However the order I get (left to right) is Neutral, Negative, Positive both on a phone running Marshmallow and Android Studio emulator configured to Jelly Bean. I use AppCompat libs, so the behavior I observe may be typical for newer Android versions. Anyway it is not Negative, Neutral, Positive (i.e. not as it was stated earlier).
