windows phone 8.1 bing 地图聚类

Question

您好，我正在使用this 链接中描述的 Windows 地图控件，并且我有一个带有多个 MapOverlays 的 MapLayer，地图上有不同的 pois。我想做集群的事情。我尝试做this，但没有 ClusteringLayer 存在，也没有 Pushpin。我该如何进行聚类？

var cluster = new ClusteringLayer();

layer = new ClusteringLayer(Mymap)
        {
            ClusterRadius = 10,
            ClusterType = ClusteringType.Grid
        };

//Add event handlers to create the pushpins 
layer.CreateClusteredItemPushpin += CreateClusteredItemPushpin1;
layer.CreateItemPushpin+=layer_CreateItemPushpin;

    private MapOverlay layer_CreateItemPushpin(object item, ClusteredPoint clusterInfo)
    {
        var x = clusterInfo.Location;
        var poi = new BuildingPoi { Coordinate = x, Buid = _selectedBuild };
        var imagePoiLocation = new Image
        {
            Source = new BitmapImage(new Uri("/Assets/MapPin.png", UriKind.Relative)),
            DataContext = poi
        };

        var over = new MapOverlay();

        imagePoiLocation.Tap += loadClickedBuilding;
        over.Content = imagePoiLocation;
        over.PositionOrigin = new Point(0.5, 0.5);
        over.GeoCoordinate = new GeoCoordinate(x.Latitude, x.Longitude);

        return over;
    }

    private MapOverlay CreateClusteredItemPushpin1(ClusteredPoint clusterInfo)
    {
        var x = clusterInfo.Location;
        var poi = new BuildingPoi { Coordinate = x, Buid = _selectedBuild };
        var imagePoiLocation = new Image
        {
            Source = new BitmapImage(new Uri("/Assets/MapPin.png", UriKind.Relative)),
            DataContext = poi
        };

        var over = new MapOverlay();

        imagePoiLocation.Tap += loadClickedBuilding;
        over.Content = imagePoiLocation;
        over.PositionOrigin = new Point(0.5, 0.5);
        over.GeoCoordinate = new GeoCoordinate(x.Latitude, x.Longitude);

        return over;
    }

由于他们没有任何 nuget 包或 dll 可直接引用，因此您需要将特定类的 source code 与相关的 .cs 文件或项目本身下载到您的机器上，例如 ClusteringLayer 和 PushPin，然后在您的 windows phone 项目中添加此项目的引用以获取 ClusteringLayer 和 PushPin 类。

查看ClusteringLayer 类的以下屏幕截图。对于其他类，只需将解决方案导入 Visual Studio，您将看到所有类的源代码。顺便说一句，ClusteringLayer 构造函数在集群中至少需要一个参数。

我建议您下载源代码并从源代码示例中熟悉它的用法。
