longitude = location.getLongitude(); //纬度
}
}
同时别忘了在AndroidManifest.xml文件中加入如下权限：
<!-- 连接互联网Internet权限 -->
<uses-permission android:name="android.permission.INTERNET" />
<!-- GPS定位权限 -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
