}

使用的时候先打开服务

 @Overridepublic 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

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