Android - Is it correct to use Event Buses (like Otto) for UI elements communication? -

can (is correct to) use event bus communicate between ui views? exemple, use communicate between fragments instead of implementing listener?

can use same instance of bus more 1 operation?

thank you

yes.

otto built reason: communicate fragments , activities aside without need of serializing through intents.

also, instance question: can reuse bus wherever want to. sometimes, though, prefer create different buses separate groups of classes communicating: example, in mvp architecture, have bus each m-v-p group, or in example, bus communicating specific service running, etc.

this example on how use library.
