android綁定服務核心代碼

1：Activity:

Intent serviceIntent= new Intent(MainActivity.this, KlineService.class);
  MainActivity.this.bindService(serviceIntent, serviceConnection, BIND_AUTO_CREATE);

private ServiceConnection serviceConnection = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
        KlineService.MyBinder binder = (KlineService.MyBinder) iBinder; //通過IBinder獲取Service
        klineService= binder.getService();
    }
    public void onServiceDisconnected(ComponentName componentName) {

    }
};

在OnDestory方法裏面取消綁定服務

MainActivity.this.unbindService(serviceConnection);
Intent intent = new Intent(MainActivity.this, KlineService.class);
MainActivity.this.stopService(intent);

2 KLineService

private String tag="KlineService";
private final IBinder binder = new MyBinder();
public class MyBinder extends Binder {
   public KlineService getService() {
        return KlineService.this;
    }
}
