Java开发者必读：高德地图公交站点查询的步行路径规划方法

随着城市的发展，公共交通系统成为人们日常出行的重要方式之一。为了提升公交出行的便利性和效率，高德地图提供了丰富的公交站点查询功能，并且还支持对站点之间的步行路径进行规划。本文将介绍如何使用Java开发实现高德地图公交站点查询的步行路径规划功能。

首先，我们需要在代码中引入高德地图的Java SDK。可以在Maven项目中添加以下依赖：

com.amap.api amap-java-sdk 1.4.0 登录后复制

String apiKey = "yourApiKey"; AMapServices aMapServices = new AMapServices(apiKey);登录后复制

DistrictSearchQuery query = new DistrictSearchQuery(); query.setKeywords("北京市"); DistrictSearch districtSearch = new DistrictSearch(query); DistrictResult districtResult = aMapServices.districtSearch(districtSearch); List districtItems = districtResult.getDistrict(); for (DistrictItem districtItem : districtItems) { String districtName = districtItem.getName(); List busStationItems = districtItem.getBusStations(); for (BusStationItem busStationItem : busStationItems) { String busStationName = busStationItem.getBusStationName(); System.out.println("District: " + districtName + ", Bus Station: " + busStationName); } }登录后复制

LatLonPoint startPoint = new LatLonPoint(39.904984, 116.405285); // 起始站点经纬度 LatLonPoint endPoint = new LatLonPoint(39.915599, 116.467402); // 目的站点经纬度 RouteSearch.WalkRouteQuery query = new RouteSearch.WalkRouteQuery(new RouteSearch.FromAndTo(startPoint, endPoint)); RouteSearch routeSearch = new RouteSearch(this); // this为当前的上下文 routeSearch.calculateWalkRouteAsyn(query); routeSearch.setRouteSearchListener(new RouteSearch.OnRouteSearchListener() { @Override public void onBusRouteSearched(BusRouteResult busRouteResult, int i) { // 不需要处理 } @Override public void onDriveRouteSearched(DriveRouteResult driveRouteResult, int i) { // 不需要处理 } @Override public void onWalkRouteSearched(WalkRouteResult walkRouteResult, int i) { if (i == 1000) { if (walkRouteResult != null && walkRouteResult.getPaths() != null && walkRouteResult.getPaths().size() > 0) { WalkPath walkPath = walkRouteResult.getPaths().get(0); List walkSteps = walkPath.getSteps(); for (WalkStep walkStep : walkSteps) { String instruction = walkStep.getInstruction(); System.out.println("Instruction: " + instruction); } } } else { System.out.println("步行路径规划失败"); } } });登录后复制
