Android 消息分发使用EventBus的实例详解

dependencies {  //最新版本  compile 'org.greenrobot:eventbus:3.0.0'   //可以翻倍提高EventBus使用效率  provided 'de.greenrobot:eventbus-annotation-processor:3.0.0-beta1'}

/** * Activity基类 */protected EventBus eb; @Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    //单例模式获取到实例并注册    eb = EventBus.getDefault();    eb.register(this);  } @Override  protected void onDestroy() {    //反注册    eb.unregister(this);    super.onDestroy();  } //主线程 @Subscribe(threadMode = ThreadMode.MAIN) public void onMainEvent(EventBean event) { } //主线程 粘性(比如传递intent使用) @Subscribe(sticky = true, threadMode = ThreadMode.MAIN) public void onMainStickEvent(EventBean event) { } //后台 @Subscribe(threadMode = ThreadMode.BACKGROUND) public void onBackgroundEvent(EventBean event) { } //重新开启一个线程来执行 @Subscribe(threadMode = ThreadMode.ASYNC) public void onAsyncEvent(EventBean event) { }

//根据不同需求自定义/** * 自定义Event消息 */public class EventBean {  public int id;//类型标识  public Object data;//数据对象  //省略constructor & getter & setter}

继承自基类Activity后：eb.post(new EventBean(1, "data"));//粘性eb.postSticky(new EventBean(1, "data"));
