构造函数方法类(用于传递参数)

 

public class ChangeFragmentEvent {private int viewId;private String ass;public ChangeFragmentEvent(int id,String ss) {this.viewId = id;this.ass=ss;}public int getViewId() {return viewId;}public String getstring (){return ass;}public void setViewId(int viewId) {this.viewId = viewId;}
}

注册

 

EventBus.getDefault().register(this);

activity监听回调

    @org.greenrobot.eventbus.Subscribe(threadMode = ThreadMode.POSTING)//MAINpublic void onMessageEvent(ChangeFragmentEvent changeFragmentEvent) {tomapte.setText("vvvvv555"+changeFragmentEvent.getstring());
//        tomapte.setText("vvvvv555");//dosomething}
