在 Mapbox Android 中添加坐标

Question

我正在使用mapbox android，我正在尝试在起点和目的地之间添加多个航路点。但是在添加一个航路点后，当它添加另一个航路点时，会出现异常“ s 坐标太多；最大坐标数为3.”

我只想在两点之间添加多个路径点并在mapbox android中的这些线上绘制路线。

{
    private void getRouteWithWaypoint(Point origin, Point destination, List<Point> wayPoints) {
        assert Mapbox.getAccessToken() != null;
        NavigationRoute.Builder builder = NavigationRoute.builder(getActivity())
                .accessToken(Mapbox.getAccessToken())
                .origin(origin)
                .destination(destination);
        if (wayPoints != null) {
            for (Point point : wayPoints) {
                builder.addWaypoint(point);
            }
        }
        builder.build().getRoute(new Callback<DirectionsResponse>() {
            @Override
            public void onResponse(@NonNull Call<DirectionsResponse> call, Response<DirectionsResponse> response) {
                Log.e(TAG, "Response code: " + response.code());
                if (response.body() == null) {
                    Log.e(TAG, "No routes found, make sure you set the right user and access token.");
                    return;
                } else if (response.body().routes().size() < 1) {
                    Log.e(TAG, "No routes found");
                    return;
                }
                currentRoute = response.body().routes().get(0);
                if (navigationMapRoute != null) {
                    navigationMapRoute.removeRoute();
                } else {
                    navigationMapRoute = new NavigationMapRoute(null, mapView, map, R.style.NavigationMapRoute);
                }
                navigationMapRoute.addRoute(currentRoute);

            }

            @SuppressLint("TimberArgCount")
            @Override
            public void onFailure(Call<DirectionsResponse> call, Throwable t) {
                Timber.e(t, "Error: %s");
            }
        });

    }}

在 Mapbox 地图上绘制根，从 Mapbox 文档复制以下代码。

private void getRoute(Point origin, Point destination) {
  NavigationRoute.builder(this)
    .accessToken(Mapbox.getAccessToken())
    .origin(origin)
    .destination(destination)
    .build()
    .getRoute(new Callback<DirectionsResponse>() {
      @Override
      public void onResponse(Call<DirectionsResponse> call, Response<DirectionsResponse> response) {
        // You can get the generic HTTP info about the response
        Log.d(TAG, "Response code: " + response.code());
        if (response.body() == null) {
          Log.e(TAG, "No routes found, make sure you set the right user and access token.");
          return;
        } else if (response.body().routes().size() < 1) {
          Log.e(TAG, "No routes found");
          return;
        }

        currentRoute = response.body().routes().get(0);

        // Draw the route on the map
        if (navigationMapRoute != null) {
          navigationMapRoute.removeRoute();
        } else {
          navigationMapRoute = new NavigationMapRoute(null, mapView, mapboxMap, R.style.NavigationMapRoute);
        }
        navigationMapRoute.addRoute(currentRoute);
      }

      @Override
      public void onFailure(Call<DirectionsResponse> call, Throwable throwable) {
        Log.e(TAG, "Error: " + throwable.getMessage());
      }
    });
}

Answer 2

请求路由的默认配置文件是

DirectionsCriteria.ProfileCriteria.PROFILE_DRIVING_TRAFFIC

此配置文件仅允许出发地和目的地之间有 1 个航路点。如果您想使用 1 个以上的航点，只需使用

PROFILE_DRIVING

即可（我认为最多可以使用 25 个航点）。

像这样：

 NavigationRoute.Builder builder = NavigationRoute.builder(getActivity())
            .accessToken(Mapbox.getAccessToken())
            .origin(origin)
            .destination(destination)
            .profile(DirectionsCriteria.ProfileCriteria.PROFILE_DRIVING);
    if (wayPoints != null) {
        for (Point point : wayPoints) {
            builder.addWaypoint(point);
        }
    }

首先，你可以得到这样一条路： (MAPBOX DIRECTIONS V10 KOTLIN)

private fun makeRequestToGetRoute(
    originPoint: Point,
    destination: Point,
    isDirectionToDriver: Boolean
) {

    val routeOptions = RouteOptions.builder()
        .applyDefaultNavigationOptions()
        .coordinatesList(listOf(originPoint, destination))
        .waypointsPerRoute(true)
        .alternatives(false)
        .build()

    mapboxNavigation.requestRoutes(routeOptions, object : NavigationRouterCallback {
        override fun onCanceled(routeOptions: RouteOptions, routerOrigin: RouterOrigin) {
        }

        override fun onFailure(reasons: List<RouterFailure>, routeOptions: RouteOptions) {
        }

        override fun onRoutesReady(
            routes: List<NavigationRoute>, routerOrigin: RouterOrigin
        ) {
            mapboxNavigation.setNavigationRoutes(routes) { _ ->

            }
            drawPolyLine(routes.first().directionsRoute.completeGeometryToPoints())
        }
    })
}

这里，我调用了drawPolyline函数，它使用点在地图上绘制线条。 功能代码如下：

 private fun drawPolyLine(pointList: List<Point>) {
        Log.d(TAG, "drawPolyLine: called draw")

        val polylineAnnotationManager: PolylineAnnotationManager =
            mapView.annotations.createPolylineAnnotationManager()
        val polylineAnnotationOptions = PolylineAnnotationOptions()
            .withPoints(pointList)
            .withLineColor("#ee4e8b")
            .withLineWidth(4.0)
        polylineAnnotationManager.create(polylineAnnotationOptions)

    }

使用这个功能，你可以画它。 withLineColor("#ee4e8b") 设置颜色，用 .withLineWidth(4.0) 设置线条。

它适用于我的项目中的mapbox v10，所以尝试一下。祝你好运
