1.EventBus：

2.build.gradle

compile 'org.greenrobot:eventbus:3.0.0'

3.onCreate

EventBus.getDefault().register(this);

4.创建

public class UserEvent {    public String username;}

public void sendEvent(View view) {    new Thread(){        @Override        public void run() {            UserEvent event = new UserEvent();            event.username="小熊";            EventBus.getDefault().post(event);        }    }.start();    EventBus.getDefault().post(new FinishEvent());}

5.onDestory（）

EventBus.getDefault().unregister(this);super.onDestroy();

6.线程

@Subscribe(threadMode = ThreadMode.MAIN)    //不管你发布的是什么线程 我都跑在 主线程public void changeText(UserEvent event){    Log.e("event","thread1:"+Thread.currentThread().getName());    mText.append(event.username);}

@Subscribe(threadMode = ThreadMode.POSTING) //发布过来是 什么线程 就运行在什么线程public void changeText(final UserEvent event){    Log.e("event","thread2:"+Thread.currentThread().getName());    runOnUiThread(new Runnable() {        @Override        public void run() {            mText.append(event.username);        }    });}

@Subscribe(threadMode = ThreadMode.BACKGROUND) //发布过来是 主线程 创建子线程 发布过来是 子线程直接运行在该子线程public void changeText(final UserEvent event){    Log.e("event","thread3:"+Thread.currentThread().getName());    runOnUiThread(new Runnable() {        @Override        public void run() {            mText.append(event.username);        }    });}

@Subscribe(threadMode = ThreadMode.ASYNC) //不管发布的是什么线程 都创建子线程public void changeText(final UserEvent event){    Log.e("event","thread4:"+Thread.currentThread().getName());    runOnUiThread(new Runnable() {        @Override        public void run() {            mText.append(event.username);        }    });}
