百度地图实现最简单的路径规划 /*设置目的地开始导航/ if (BaiduNaviManager.isNaviInited()) { routeplanToNavi(); }============================ /** * 路径规划相关 */ 阅读详情

前段时间项目需要做路径规划，简单的研究了下。不过，后来没用到

效果图：

实现的是从北京西二旗地铁站 到 北京百度科技园的路径规划。这里是固定的，可以根据自己需要改成可输入起止位置

这里面有很多坑，需要一一踩过才知道。

记下来，我们来实现功能吧：

至于引入sdk、配置权限等，就不做具体的介绍了，网上或者百度地图官方文档都可以查到。

只许看加粗的主要部分就可以，因为还有其他的功能，所以显得冗余。

1、显示地图页面Activity，我取名叫FiveActivity
