Custom event listener in Android?

Question

Java

Good!
I want to make my own event listener, I used to do it on AS3, everything is simple there, we inherit, create an event, give a name, sign / unsubscribe everything that is needed. I want to do the same on android and I don’t understand what wild crutches with interfaces, etc. dregs like one of 10 variants of the same thing - this rubbish is really the realization of what I'm looking for or I didn't dug it up

EventBus is called what you want. From my t.z. - an antipattern, it is necessary to use very carefully.
For example - from greenrobot .
