EventBus的Post方法发送事件

例：

组件与组件之间的传递代替Intent,线程间的通讯代替handler

加依赖：

dependencies {     compile 'org.greenrobot:eventbus:3.0.0' }

加权限：

MainActivity

/**  * Module,EventBus,2Activity  * <p>  * Module * <p>  * EventBus,EventBus * <p>  * EventBus, * <p>  * EventBusPost * <p>  * , *  * Intent,handler  */ public class MainActivity extends AppCompatActivity implements View.OnClickListener {     private Button button;     private TextView tv_title;     private EventBus mEventBus;     @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);         initView();         //EventBUsnewEventBUs,        mEventBus = EventBus.getDefault();         //EventBus,:EventBus,:1.娉ㄨВ    2.        mEventBus.register(this);     }      @Override     protected void onDestroy() {         super.onDestroy();         //EventBUs        mEventBus.unregister(this);     }      /** ,     * //:,,public,     * ::      * ThreadMode.MAIN     * ,     */     @Subscribe(threadMode = ThreadMode.MAIN)     public void eBSAEventBus(EBMessage ebMessage){         //        tv_title.setText(ebMessage.Message);         Log.d("EventBusThread","MAIN"+Thread.currentThread().getName());     }  //    @Subscribe(threadMode = ThreadMode.POSTING) //    public void eBSAEventBus1(EBMessage ebMessage){ //        Log.d("EventBusThread","POSTING"+Thread.currentThread().getName()); //    } // //    @Subscribe(threadMode = ThreadMode.ASYNC) //    public void eBSAEventBus2(EBMessage ebMessage){ //        Log.d("EventBusThread","ASYNC"+Thread.currentThread().getName()); //    } // //    @Subscribe(threadMode = ThreadMode.BACKGROUND) //    public void eBSAEventBus3(EBMessage ebMessage){ //        Log.d("EventBusThread","BACKGROUND"+Thread.currentThread().getName()); //    }      @Override     public void onClick(View v) {         switch (v.getId()) {             case R.id.button: //                startActivity(new Intent(this,EventBusSendActivity.class));                 new Thread(){                     public void run() {                         mEventBus.post(new EBMessage(","));                     };                 }.start();                 break;         }     }
