EventBusDemo

This is a simple demo using EventBus. EventBus is a publish/subscriber event bus optimized for Android and developed by Markus Junginger in Greenrobot.

EventBus in 3 steps

1. Define events:

   public class GlobalBus {
       private static EventBus eventBus;
   
       public static EventBus getEventBus() {
           if (eventBus == null) {
               eventBus = EventBus.getDefault();
           }
           return eventBus;
       }
   }

2. Prepare subscribers: Declare and annotate your subscribing method, optionally specify a thread mode:

   @Subscribe(sticky = true)
   public void onMessageEvent(EventMessageList event) { /* Do something */ }

   Register and unregister your subscriber. For example on Android, activities and fragments should usually register according to their life cycle:

   @Override
   protected void onStart() {
       super.onStart();
       GlobalBus.getEventBus().register(this);
   }
   
   @Override
   protected void onStop() {
       GlobalBus.getEventBus().unregister(this);
       super.onStop();
   }

3. Post events:

   GlobalBus.getEventBus().postSticky(new EventMessageList(messageList));
