标签:百度地图   百度定位   百度地图api-v4-2   

这几天在看郭霖老师的大作,在百度地图这一张卡的好久,原因是因为百度更新迭代的速度太快了,导致老师的书上的版本已经淘汰又淘汰了,不过还是给了我很多的启发的啊。今晚自己就实现了一下百度地图的定位功能。

百度地图API的什么的,也就不多说了。官网上介绍的也比较详细,还都是中文的,仔细阅读下就行,对了,我用的是v4-2的版本。感觉只有晚上11点以后的工作效率才会翻倍啊,大家有没有这个体会啊,最近想做一款跑步的软件,当然是很简单的那种,做完了会贴上代码和大家来讨论的。

布局文件就不贴代码了,就是一个TextView。对了,不知道为什么,我有一款华为的Z87,是没有SM卡的,但是连接的wifi,却不能定位成功。但是另一款锤子去可以,如果大家知道的话,请告知。
