无法创建从一个点的路线到另一个Android版的ArcGIS [英] Cannot create route from one point to another ArcGIS Android

问题描述

我一直很努力创建两个点之间的航线（的startPoint，终端）。但我得到以下错误：

I've been trying very hard to create a route between two points(startPoint, endPoint). But i am getting the following error:

在停止位置位置1就是非定位。位置位置2中的停止就是非定位。至少需要2有效站。 停止不包含有效的输入任何路线。

我已经张贴在gis.stackexchange.com这个问题，并geonet.esri.com并没有得到除一个答复这是没有帮助的。

I've posted this question on gis.stackexchange.com and geonet.esri.com and didn't get a reply except one which was not helpful.

我的code：

private final String routeTaskURL = "http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Network/USA/NAServer/Route";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mMapView = (MapView) findViewById(R.id.map);
    mMapView.enableWrapAround(true);
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                UserCredentials userCredentials = new UserCredentials();
                userCredentials.setUserToken(token, clientID);
                RouteTask routeTask = RouteTask.createOnlineRouteTask(routeTaskURL, userCredentials);
                RouteParameters routeParameters = routeTask.retrieveDefaultRouteTaskParameters();
                NAFeaturesAsFeature naFeatures = new NAFeaturesAsFeature();

                Point startPoint = new Point(36.793653, -119.866896);
                Point stopPoint = new Point(36.795488, -119.853345);

                StopGraphic startPnt = new StopGraphic(startPoint);
                StopGraphic stopPnt = new StopGraphic(stopPoint);

                naFeatures.setFeatures(new Graphic[] {startPnt, stopPnt});
                routeParameters.setStops(naFeatures);

                RouteResult mResults = routeTask.solve(routeParameters);
                List<Route> routes = mResults.getRoutes();
                System.out.println(mResults.getRoutes());

                Route mRoute = routes.get(0);
                Geometry geometry = mRoute.getRouteGraphic().getGeometry();
                Graphic symbolGraphic = new Graphic(geometry, new SimpleLineSymbol(Color.BLUE, 3));
                mGraphicsLayer.addGraphic(symbolGraphic);
                System.out.println(mResults.getStops());
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }).start();
}

我在网上搜索。许多开发者/都面临这个问题。我已经尝试了所有解决方案，但没有一次成功。我的 routeTaskURL 在ArcGIS路由示例应用程序。这是在 文档 如果我在浏览器中打开它给我的403错误。

I've searched the internet. Many developers were/are facing this problem. I've tried all the solutions but none of them worked. I got routeTaskURL from the ArcGIS Routing Sample app. The link which is given in the documentation of ArcGIS maps gives me the 403 error if i open it in the browser.

注意：令牌和clientID的在第一步中声明，他们都从那里我注册了我的应用程序在ArcGIS开发者控制台采取

有什么建议？

推荐答案

您的X和Y值的切换。改成这样：

Your X and Y values are switched. Change to this:

Point startPoint = new Point(-119.866896, 36.793653);
Point stopPoint = new Point(-119.853345, 36.795488);

查看<一个href=\"https://developers.arcgis.com/android/api-reference/reference/com/esri/core/geometry/Point.html\"相对=nofollow> 点类文档了解，该构造函数的参数为​​（X，Y），不（Y，X）。您正在使用的航线有4326默认的空间参考，这是未投影经度和纬度。 -119.866896和-119.853345无效纬度（y）的值，但它们是有效的经度（x）的值。

See the Point class documentation to learn that the constructor parameters are (x, y), not (y, x). The route service you're using has a default spatial reference of 4326, which is unprojected longitude and latitude. -119.866896 and -119.853345 are not valid latitude (y) values, but they are valid longitude (x) values.
