在Service中自定義Binder類，實現方法getService；覆寫Service的onBind方法
public?class?MainService?extends?Service?{
????@Override ????public?void?onCreate()?{ ????????super.onCreate(); ????}
????@Override ????public?void?onDestroy()?{ ????????super.onDestroy(); ????}
????@Override ????public?IBinder?onBind(Intent?intent)?{ ????????return?new?MsgBinder(); ????}
????public?class?MsgBinder?extends?Binder?{ ????????/** ?????????*?獲取當前Service的實例 ?????????*? ?????????*?@return ?????????*/ ????????public?MainService?getService()?{ ????????????return?MainService.this; ????????} ????} }
Activity中通過bindService綁定Service，Activity結束時斷開綁定（注意：綁定時會自動啟動Service，Activity終止時Service也會停止，要讓Service后臺運行應該同時調用StartService）
從ServiceConnection的回調方法中可以獲取自定義的Binder實例，從而獲取Service實例，即可方便的進行通信

? ??@Override ????public?void?onCreate(Bundle?savedInstanceState)?{ ????????super.onCreate(savedInstanceState); ? ? ? ? Intent?intent?=?new?Intent(ActivityMain.this,?MainService.class); ????????this.startService(intent); ????????bindService(intent,?conn,?Context.BIND_AUTO_CREATE); ? ? }
????@Override ????public?void?onDestroy()?{ ????????this.unbindService(conn); ????????super.onDestroy(); ????}
????MainService?svc;
????private?ServiceConnection?conn?=?new?ServiceConnection()?{ ????????@Override ????????public?void?onServiceDisconnected(ComponentName?name)?{ ????????}
????????@Override ????????public?void?onServiceConnected(ComponentName?name,?IBinder?service)?{ ????????????MsgBinder?binder?=?(MsgBinder)?service; ????????????svc?=?binder.getService(); ????????} ????};
