问题：
Here API：使用Android sdk获取错误的传输路由信息
巫马庆
我尝试使用Android sdk获取一个基本的传输路线，但我缺少我需要的数据。
基本上，我想得到的数据和我们出发的计划者完全一样。在那里你可以看到台阶，它们的出发和到达时间，哪种类型的过境，它出发或到达哪个站台。
所以当我尝试在Android sdk中使用RoutePlan时，它给了我一个错误的tta，它比我所看到的没有任何额外步骤的情况下应该多了一个小时。也没有显示台阶的站台和出发/到达时间。这同样适用于将路由请求发送到Postman中的路由api。
我的问题是，我如何能够检索与使用Android SDK的Here We Go规划器和应用程序完全相同的数据？
更新：我的Here项目页面上也写着“估计的公共交通”，对于我的大多数请求，这是它应该是怎样的，还是应该是其他的东西？
更新2：我试过使用here we go Maps1、postman[代码在下面]和android sdk[代码在下面]进行相同的路线，得到了非常不同的结果。
邮递员请求：https://route.api.here.com/routing/7.2/calculateroute.json？app_id=app_id&app_code=app_code&waypoint0=52.3146653,5.0248838&waypoint1=52.6381,4.74059999999999972&departure=now&mode=fastest；publictransport&combinechange=true
结果：

在Android中记录该路线的出发时间和持续时间，结果为:i/departure ；time:10:00i/duration:02:51
使用以下代码段：规划：
RoutePlan routePlan = new RoutePlan();
RouteOptions routeOptions = new RouteOptions();
routeOptions.setTransportMode(RouteOptions.TransportMode.PUBLIC_TRANSPORT);
routeOptions.setRouteType(RouteOptions.Type.FASTEST);
routeOptions.setRouteCount(3);
routeOptions.setLocale(Locale.getDefault());
if (toggleSwitch.getCheckedTogglePosition() == 0) {
routeOptions.setTime(selected_time, RouteOptions.TimeType.DEPARTURE);
}
else {
// Arrival time
}
routePlan.setRouteOptions(routeOptions);
// Select Waypoints for your routes
routePlan.addWaypoint(new RouteWaypoint(start_address_coordinate));
routePlan.addWaypoint(new RouteWaypoint(end_address_coordinate));
router.calculateRoute(routePlan, new RouterListener());
结果侦听器：
private final class RouterListener implements CoreRouter.Listener {
// Method defined in Listener
public void onProgress(int percentage) {
// Display a message indicating calculation progress
}
// Method defined in Listener
public void onCalculateRouteFinished(List<RouteResult> routeResult, RoutingError error) {
// If the route was calculated successfully
if (error == RoutingError.NONE) {
progressBar.setVisibility(View.GONE);
planButton.setEnabled(true);
Long start_time = routeResult.get(0).getRoute().getManeuvers().get(0).getStartTime().getTime();
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm", Locale.getDefault());
String start_date = sdf.format(new Date(start_time));
Date duration = new Date(routeResult.get(0).getRoute().getTtaIncludingTraffic(Route.WHOLE_ROUTE).getDuration() * 1000);
Log.i("Departure time", start_date);
Log.i("Duration", sdf.format(duration));
}
else {
// Display a message indicating route calculation failure
Log.e("Route Calculation ERROR", error.toString());
}
}
}

根据HERE路由API的PT文档：
路由API通过两种方法之一计算公共交通路线：
- 估计路由-使用聚合数据估计路由。
- 时间表路由-使用动态数据提供更精确、更详细的路由。
以上两者的区别如何在http://refclient.ext.here.com/上播放
根据Android mSDK的文档，您可以使用已知的在线时间表信息计算过境路线，但免费帐户没有启用此功能SDK-route-pt-testable，（文档中还没有，很抱歉）因此免费帐户将使用估计路由（不是时间表路由），结果将与路由API的结果相对应，用于公共交通。（请记住路由API设置请离开时间参数，否则应使用默认的时间表进行计算）
如果您想在mSDK中使用SDK-Route-PT-Tembodyhtml" target="_blank">功能，请与我们联系以获取有关以下内容的更多详细信息：
