Android定位开发之百度定位、高德定位、腾讯定位，三足鼎立一起为我所用！

发表于   |   分类于   |  

这几天的项目不是很紧，于是想为未来可能要做的项目做一些技术储备。
下一个项目很有可能是定位开发，需要用到手机定位功能，于是查了查现在比较流行的第三方定位，最火的基本上就是百度定位>高德定位>腾讯定位了。
想了想不如做一个DEMO把三种定位方式混合一下试试。

记录一下开发中遇到的问题：

百度地图：没什么问题，用起来很方便。
高德地图：LocationProviderProxy.AMapNetwork 只支持网络定位，无法纯GPS定位，如果想要纯GPS定位就必须把这个参数改成LocationManagerProxy.GPS_PROVIDER。很蛋疼，这里需要自己来逻辑判断一下。
腾讯地图：如果想要纯GPS定位的话，需要把定位坐标改成地球坐标：mLocationManager.setCoordinateType(TencentLocationManager.COORDINATE_TYPE_WGS84);
但是面临的问题是这个坐标没法反地理编码。如果想反地理编码，就必须把坐标改成火星坐标，mLocationManager.setCoordinateType(TencentLocationManager.COORDINATE_TYPE_GCJ02);
但是这样又没法纯GPS定位，所以我个人觉得腾讯定位只要用他的网络定位就好了，不要用他的GPS定位了 好麻烦。

在我所在的位置测试的话，三种定位的网络定位，反地理编码最准确的是：腾讯定位，其次是百度定位，最差的是高德定位。
