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。

        catch (Exception e)
        {
            e.getCause();
        }
        return webTiledLayer;
    }

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);
