高德地图步行路线规划代码示例

以下是将高德地图API用于步行路线规划的代码示例：

public void routeSearch(List<LatLonPoint> wayPoints, Integer showFields, final SearchBack searchBack) {
    try {
        WalkRouteQuery query = new WalkRouteQuery(new RouteSearch.FromAndTo(wayPoints.get(0), wayPoints.get(wayPoints.size() - 1)));
        if (showFields != null) query.setShowRouteDetail(showFields);
        getRouteSearch().setRouteSearchListener(new RouteSearch.OnRouteSearchListener() {
            @Override
            public void onWalkRouteSearched(WalkRouteResult walkRouteResult, int code) {
                Map<String,Object> map = new HashMap<>();
                List<WalkPath> walkPaths = walkRouteResult.getPaths();
                List<Map<String,Object>> paths = new ArrayList<>();
                for (WalkPath walkPath : walkPaths) {
                    Map<String,Object> pathMap = new HashMap<>();
                    String polyline = AMapUtil.convertLatLngListToString(walkPath.getSteps().get(0).getPolyline());
                    pathMap.put('polyline', polyline);
                    pathMap.put('distance', walkPath.getDistance());
                    pathMap.put('duration', walkPath.getDuration());
                    paths.add(pathMap);
                }
                map.put('paths', paths);
                searchBack.back(code, map);
            }

            @Override
            public void onDriveRouteSearched(DriveRouteResult driveRouteResult, int i) {
                // do nothing
            }

            @Override
            public void onRideRouteSearched(RideRouteResult rideRouteResult, int i) {
                // do nothing
            }
        });
        getRouteSearch().calculateWalkRouteAsyn(query);
    } catch (AMapException e) {
        e.printStackTrace();
    }
}

请注意，代码中使用了AMapUtil.convertLatLngListToString()方法将经纬度列表转换为字符串形式的路线。您需要根据您的实际情况替换此方法。
