一、概述
这一章我们学习高德地图的路线规划，主要分为驾车路线，步行路线，公交路线，骑行路线。在高德地图中数据的获取使用方式都比较相似，本章的路线规划查询也不例外。需要一个查询实列，然后设置查询条件，查询结果在监听方法中回调。
二、本章内容
通过RouteSearch类，来进行路线的查询
routeSearch = new RouteSearch(this);
routeSearch.setRouteSearchListener(this);
//实现不同路线查询的回调方法
@Override
public void onBusRouteSearched(BusRouteResult busRouteResult, int i) {
}
@Override
public void onDriveRouteSearched(DriveRouteResult driveRouteResult, int i) {
}
@Override
public void onWalkRouteSearched(WalkRouteResult walkRouteResult, int i) {
}
@Override
public void onRideRouteSearched(RideRouteResult rideRouteResult, int i) {
}
1.驾车路线
//构建开始点与终止点的经纬度数据
RouteSearch.FromAndTo fromAndTo = new RouteSearch.FromAndTo(
new LatLonPoint(start.getLat(), start.getLng()),
new LatLonPoint(end.getLat(), end.getLng()));
// fromAndTo包含路径规划的起点和终点，drivingMode表示驾车模式
// 第三个参数表示途经点（最多支持16个）， 第四个参数表示避让区域（最多支持32个），第五个参数表示避让道路
RouteSearch.DriveRouteQuery query = new RouteSearch.DriveRouteQuery(
fromAndTo, DRIVING_SINGLE_DEFAULT, null, null, "");
routeSearch.calculateDriveRouteAsyn(query);
RouteSearch.DriveRouteQuery构造方法的第二个参数为驾车模式，即驾车策略

2.步行路线
RouteSearch.FromAndTo fromAndTo = new RouteSearch.FromAndTo(
new LatLonPoint(start.getLat(), start.getLng()),
new LatLonPoint(end.getLat(), end.getLng()));
RouteSearch.WalkRouteQuery query = new RouteSearch.WalkRouteQuery(
fromAndTo, RouteSearch.WALK_DEFAULT);
routeSearch.calculateWalkRouteAsyn(query);
在步行路线中提供了两种模式 RouteSearch.WALK_DEFAULT 和 RouteSearch.WALK_MULTI_PATH。
3.公交路线
RouteSearch.FromAndTo fromAndTo = new RouteSearch.FromAndTo(
new LatLonPoint(start.getLat(), start.getLng()),
new LatLonPoint(end.getLat(), end.getLng()));
RouteSearch.BusRouteQuery query = new
// 第三个参数表示公交查询城市区号，第四个参数表示是否计算夜班车，
//0表示不计算,1表示计算RouteSearch.BusRouteQuery(
fromAndTo, RouteSearch.BUS_LEASE_WALK, "028", 0);
routeSearch.calculateBusRouteAsyn(query);
注意：公交路线在查询后返回结果可能有多条路线，每一条路线又被分为了很多段，例如：到达目的地可能会换成公交，步行等。在这每一段中会有步行数据与公交数据，因为定位开始与结束不一定就在公交站附近，所以一般的拼接整个路线时，把步行数据点放在前面然后再添加公交路线的点，最后一段一般没有公交路线点的数据，只有步行点的数据
4.骑行路线
RouteSearch.FromAndTo fromAndTo = new RouteSearch.FromAndTo(
new LatLonPoint(start.getLat(), start.getLng()),
new LatLonPoint(end.getLat(), end.getLng()));
RouteSearch.RideRouteQuery query = new RouteSearch.RideRouteQuery(
fromAndTo, RouteSearch.RIDING_DEFAULT);
routeSearch.calculateRideRouteAsyn(query);
