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 + "]";

     }

 }

     // 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！

                     SystemClock.sleep(1000);

                 }

             }
