}

使用的时候先打开服务

 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Intent i = new Intent(getActivity(),GPSService.class);
        getActivity().startService(i);
    }

使用完成后关闭服务

@Override
    public void onStop() {
        super.onStop();
        Intent i = new Intent(getActivity(),GPSService.class);
        getActivity().stopService(i);
    }
