MyEvent:

 package com.zzw.testeventbus;

 public class MyEvent {
     public int id;
     public String content;

     public MyEvent() {
         super();

     }

     @Override
     public String toString() {
         return "MyEvent [id=" + id + ", content=" + content + "]";
     }

 }

MainActivity：

     // Main线程，这个与Android UI线程密切相关，可以在里面设置UI值，不要阻塞它！

EventService:

 import android.os.SystemClock;
 import de.greenrobot.event.EventBus;

 public class EventService extends Service {

     }

     private void task() {
         new Thread(new Runnable() {

             @Override
             public void run() {
                 for (int i = 1; i <= 100; i++) {
                     MyEvent event = new MyEvent();
                     event.id = i;
                     event.content = "傻逼" + i;
                     EventBus.getDefault().post(event);
                     SystemClock.sleep(1000);
                 }
             }
         }).start();
     }

     @Override
     public int onStartCommand(Intent intent, int flags, int startId) {
         task();
         return super.onStartCommand(intent, flags, startId);
