Android 高德地图 步行 路线规划

路线规划就是给设置一个监听，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 对象

= new (this);

第 2 步，设置数据回调监听器

.er(this);

第 3 步，设置搜索参数

通过 (. , int mode) 设置搜索条件。其中：

，路径的起终点；

mode，计算路径的模式。SDK提供两种模式：. 和 .。

//初始化query对象，是包含起终点信息，是步行路径规划的模式

query = new (, );

第 4 步，发送请求

使用类 的 yn( query) 方法进行步行规划路径计算。

.yn(query);//开始算路

第 5 步，接收数据

在 .r 接口回调方法 void ( ,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，获取骑行的路径。

2）.()可以获取到 列表，步行路径的详细信息可参考 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）
