The publisher is Send events subscriber Is to receive events

gradle

compile ‘org.greenrobot:eventbus:3.0.0’

1. Defining events

public static class MessageEvent { /* Additional fields if needed */ } // Defining events This is the data entity class you want to transfer

2. Prepare subscribers @Subscribe(threadMode = ThreadMode.MAIN) public void onMessageEvent(MessageEvent event) {/* Do something */}; // subscriber Method of receiving data threadMode Is running in what thread mode http://greenrobot.org/eventbus/documentation/delivery-threads-threadmode/

Registering and unregistering subscribers

@Override public void onStart() { super.onStart(); EventBus.getDefault().register(this); }

@Override public void onStop() { super.onStop(); EventBus.getDefault().unregister(this); }

3. Send events

EventBus.getDefault().post(new MessageEvent());
