路线规划就是给RouteSearch设置一个监听，里面有步行规划，骑车，驾车，公交等线路的规划

第 1 步，初始化 RouteSearch 对象

routeSearch = new RouteSearch(this);

第 2 步，设置数据回调监听器

routeSearch.setRouteSearchListener(this);

第 3 步，设置搜索参数

通过 WalkRouteQuery(RouteSearch.FromAndTo fromAndTo, int mode) 设置搜索条件。其中：

fromAndTo，路径的起终点；

mode，计算路径的模式。SDK提供两种模式：RouteSearch.WALK_DEFAULT 和 RouteSearch.WALK_MULTI_PATH。

//初始化query对象，fromAndTo是包含起终点信息，walkMode是步行路径规划的模式

WalkRouteQuery query = new WalkRouteQuery(fromAndTo, walkMode);

第 4 步，发送请求

使用类 RouteSearch 的 calculateWalkRouteAsyn(WalkRouteQuery query) 方法进行步行规划路径计算。

routeSearch.calculateWalkRouteAsyn(query);//开始算路

第 5 步，接收数据

在 RouteSearch.OnRouteSearchListener 接口回调方法 void onWalkRouteSearched(WalkRouteResult walkRouteResult,int rCode) 处理步行规划路径结果。返回的信息中您可以获得路段的距离、步行的预计时间、步行路段的坐标点、步行路段的道路名称、导航主要操作等信息。显示效果如下：

说明：

1)可以在回调中解析result，获取骑行的路径。

2)result.getPaths()可以获取到 WalkPath 列表，步行路径的详细信息可参考 WalkPath 类。

3)返回结果成功或者失败的响应码。1000为成功，其他为失败(详细信息参见网站开发指南-实用工具-错误码对照表)
