Android Service

service中也有一系列生命周期的方法：
IBinder onBinder(Intent intent)
void onCreate()
void onDestroy()
int onStartCommand(Intent intent, int flags, int startId)
boolean onUnbind(Intent intent)

public class MyService extends Service {    public static final String TAG="mTimer";    public int NOTIFICATION_ID=0x123;    public int count;    @Override    public void onCreate() {        super.onCreate();        Log.e(TAG, "Service is Create");    }    @Override    public int onStartCommand(Intent intent, int flags, int startId) {        Log.e(TAG,"Service is Start");        return super.onStartCommand(intent, flags, startId);    }    @Override    public void onDestroy() {        super.onDestroy();        Log.e(TAG,"this Service is destroy");    }    @Override    public boolean onUnbind(Intent intent) {        Log.e(TAG,"Service is Unbinded");        return true;    }    @Nullable    @Override    public IBinder onBind(Intent intent) {        return myBinder;    }    class MyBinder extends Binder{        public int getCount(){            return count;        }        public void startFromMine(){            Log.e(TAG,"Service is Connection");        }    }}

启动和关闭service，以及绑定和解除绑定可以直接在button的事件里进行

 public void ben_start(View view){        Intent startIntent=new Intent(this,MyService.class);        startService(startIntent);    }    public void btn_stop(View view){        Intent stopIntent=new Intent(this,MyService.class);        stopService(stopIntent);    }    public void btn_bind(View view){        Intent bindIntent=new Intent(this,MyService.class);        bindService(bindIntent, connection, BIND_AUTO_CREATE);    }    public void btn_getCount(View view){        Log.e("---------",""+myBinder.getCount());    }    public void btn_unBind(View view){        unbindService(connection);    }

其中绑定的是IBinder对象，绑定后Activity就可以与Service进行通信。
btn_getCount()这个方法就是通过IBinder对象获取在Service中设置的数据值
