看了很多资料，都是以前老版本的百度sdk，继承的还是MapActivity。我这个是仿照官网的demo写的百度地图定位，但是进去之后没有定位，只在地图初始化的北京那个位置。求高手帮我看看哪里出问题了，谢谢。在线等。 --------------------编程问答-------------------- 新版不是把定位剥离出一个单独的定位SDK了么？ --------------------编程问答--------------------
是啊，BDLocationListener 这个类就是新版的sdk里面引用的。 --------------------编程问答-------------------- 我贴一下权限和服务吧
<?xml version="1.0" encoding="utf-8"?>--------------------编程问答-------------------- 应该是重写onReceiveLocation，你写在了onReceivePoi里面。你写错了

然后在onReceiveLocation加上
objpoint=new GeoPoint((int)(locData.latitude* 1e6), (int)(locData.longitude * 1e6));
mapController.setCenter(objpoint); --------------------编程问答-------------------- http://blog.csdn.net/xiaanming/article/details/11380619看看这个吧，希望对你有帮助
