安卓智能地图开发与实施十七：使用天地图 - ArcGIS Runtime SDK for Android（Version 100.1.0）

0
分享 2017-08-21
WebTiledLayer
100.1的新版本最大的亮点是三维，同时新加入了图层类型和可扩展的切片图层WebTiledLayer。继承自ServiceImageTiledLayer。BingMapsLayer和OpenStreetMapLayer继承自ServiceImageTiledLayer。通过设置WebTiledLayer参数便可以在ArcGIS Runtime SDK for Android的环境中使用天地图服务。

天地图相关参数



对天地图和ArcGIS参数不太清楚的可以参考： <a href="http://blog.csdn.net/arcgis_al ... erral

定义天地图相关参数

使用实例
三维场景中使用：需要Web墨卡托投影的
 
mainSceneView = (SceneView) mainSceneViewContainer.findViewById(R.id.mainSceneView);

        ArcGISScene scene = new ArcGISScene();

        WebTiledLayer webTiledLayer = TianDiTuMethodsClass.CreateTianDiTuTiledLayer(TianDiTuMethodsClass.LayerType.TIANDITU_VECTOR_MERCATOR);

        Basemap tdtBasemap =new Basemap(webTiledLayer);

        WebTiledLayer webTiledLayer1 = TianDiTuMethodsClass.CreateTianDiTuTiledLayer(TianDiTuMethodsClass.LayerType.TIANDITU_VECTOR_ANNOTATION_CHINESE_MERCATOR);

        tdtBasemap.getBaseLayers().add(webTiledLayer1);

        scene.setBasemap(tdtBasemap);

        mainSceneView.setScene(scene);

        mainSceneView.setAttributionTextVisible(false);

二维中使用


 
WebTiledLayer webTiledLayer = TianDiTuMethodsClass.CreateTianDiTuTiledLayer(TianDiTuMethodsClass.LayerType.TIANDITU_VECTOR_2000);

        Basemap tdtBasemap =new Basemap(webTiledLayer);

        WebTiledLayer webTiledLayer1 = TianDiTuMethodsClass.CreateTianDiTuTiledLayer(TianDiTuMethodsClass.LayerType.TIANDITU_VECTOR_ANNOTATION_CHINESE_2000);

        tdtBasemap.getBaseLayers().add(webTiledLayer1);

mainMapView.getMap().setBasemap(tdtBasemap);
