1、WebTiledLayer
WebTiledLayer是100.1后新加入的图层类型，用于定义一个可扩展的切片图层，该图层根据URL从切片服务器中请求图像，它提供了一种将非ArcGIS Services作为图层继承到地图中的简单方法。
URL通常遵循：http://{subDomain}.tile.opencyclemap.org/cycle/{level}/{col}/{row}.png
2、在Android Studio中新建TianDiTuMethodClass
2.1 定义天地图相关参数
想了解天地图和ArcGIS参数的区别，可参考此文：

2.2 定义天地图可用服务类型枚举
public enum LayerType { /** * 天地图矢量墨卡托投影地图服务 */ TIANDITU_VECTOR_MERCATOR, /** * 天地图矢量墨卡托中文标注 */ TIANDITU_VECTOR_ANNOTATION_CHINESE_MERCATOR, /** * 天地图矢量墨卡托英文标注 */ TIANDITU_VECTOR_ANNOTATION_ENGLISH_MERCATOR, /** * 天地图影像墨卡托投影地图服务 */ TIANDITU_IMAGE_MERCATOR, /** * 天地图影像墨卡托投影中文标注 */ TIANDITU_IMAGE_ANNOTATION_CHINESE_MERCATOR, /** * 天地图影像墨卡托投影英文标注 */ TIANDITU_IMAGE_ANNOTATION_ENGLISH_MERCATOR, /** * 天地图地形墨卡托投影地图服务 */ TIANDITU_TERRAIN_MERCATOR, /** * 天地图地形墨卡托投影中文标注 */ TIANDITU_TERRAIN_ANNOTATION_CHINESE_MERCATOR, /** * 天地图矢量国家2000坐标系地图服务 */ TIANDITU_VECTOR_2000, /** * 天地图矢量国家2000坐标系中文标注 */ TIANDITU_VECTOR_ANNOTATION_CHINESE_2000, /** * 天地图矢量国家2000坐标系英文标注 */ TIANDITU_VECTOR_ANNOTATION_ENGLISH_2000, /** * 天地图影像国家2000坐标系地图服务 */ TIANDITU_IMAGE_2000, /** * 天地图影像国家2000坐标系中文标注 */ TIANDITU_IMAGE_ANNOTATION_CHINESE_2000, /** * 天地图影像国家2000坐标系英文标注 */ TIANDITU_IMAGE_ANNOTATION_ENGLISH_2000, /** * 天地图地形国家2000坐标系地图服务 */ TIANDITU_TERRAIN_2000, /** * 天地图地形国家2000坐标系中文标注 */ TIANDITU_TERRAIN_ANNOTATION_CHINESE_2000 }2.3 通过天地图可用枚举类型获取WebTiledLayer
public static WebTiledLayer CreateTianDiTuTiledLayer(LayerType layerType) { WebTiledLayer webTiledLayer = null; String mainUrl = ""; String mainName = ""; TileInfo mainTileInfo = null; Envelope mainEnvelope = null; boolean mainIs2000 = false; try { switch (layerType) { case TIANDITU_VECTOR_2000: mainUrl = URL_VECTOR_2000; mainName = LAYER_NAME_VECTOR; mainIs2000 = true; break; case TIANDITU_VECTOR_MERCATOR: mainUrl = URL_VECTOR_MERCATOR; mainName = LAYER_NAME_VECTOR; break; case TIANDITU_IMAGE_2000: mainUrl = URL_IMAGE_2000; mainName = LAYER_NAME_IMAGE; mainIs2000 = true; break; case TIANDITU_IMAGE_ANNOTATION_CHINESE_2000: mainUrl = URL_IMAGE_ANNOTATION_CHINESE_2000; mainName = LAYER_NAME_IMAGE_ANNOTATION_CHINESE; mainIs2000 = true; break; case TIANDITU_IMAGE_ANNOTATION_ENGLISH_2000: mainUrl = URL_IMAGE_ANNOTATION_ENGLISH_2000; mainName = LAYER_NAME_IMAGE_ANNOTATION_ENGLISH; mainIs2000 = true; break; case TIANDITU_IMAGE_ANNOTATION_CHINESE_MERCATOR: mainUrl = URL_IMAGE_ANNOTATION_CHINESE_MERCATOR; mainName = LAYER_NAME_IMAGE_ANNOTATION_CHINESE; break; case TIANDITU_IMAGE_ANNOTATION_ENGLISH_MERCATOR: mainUrl = URL_IMAGE_ANNOTATION_ENGLISH_MERCATOR; mainName = LAYER_NAME_IMAGE_ANNOTATION_ENGLISH; break; case TIANDITU_IMAGE_MERCATOR: mainUrl = URL_IMAGE_MERCATOR; mainName = LAYER_NAME_IMAGE; break; case TIANDITU_VECTOR_ANNOTATION_CHINESE_2000: mainUrl = URL_VECTOR_ANNOTATION_CHINESE_2000; mainName = LAYER_NAME_VECTOR_ANNOTATION_CHINESE; mainIs2000 = true; break; case TIANDITU_VECTOR_ANNOTATION_ENGLISH_2000: mainUrl = URL_VECTOR_ANNOTATION_ENGLISH_2000; mainName = LAYER_NAME_VECTOR_ANNOTATION_ENGLISH; mainIs2000 = true; break; case TIANDITU_VECTOR_ANNOTATION_CHINESE_MERCATOR: mainUrl = URL_VECTOR_ANNOTATION_CHINESE_MERCATOR; mainName = LAYER_NAME_VECTOR_ANNOTATION_CHINESE; break; case TIANDITU_VECTOR_ANNOTATION_ENGLISH_MERCATOR: mainUrl = URL_VECTOR_ANNOTATION_ENGLISH_MERCATOR; mainName = LAYER_NAME_VECTOR_ANNOTATION_ENGLISH; break; case TIANDITU_TERRAIN_2000: mainUrl = URL_TERRAIN_2000; mainName = LAYER_NAME_TERRAIN; mainIs2000 = true; break; case TIANDITU_TERRAIN_ANNOTATION_CHINESE_2000: mainUrl = URL_TERRAIN_ANNOTATION_CHINESE_2000; mainName = LAYER_NAME_TERRAIN_ANNOTATION_CHINESE; mainIs2000 = true; break; case TIANDITU_TERRAIN_MERCATOR: mainUrl = URL_TERRAIN_MERCATOR; mainName = LAYER_NAME_TERRAIN; break; case TIANDITU_TERRAIN_ANNOTATION_CHINESE_MERCATOR: mainUrl = URL_TERRAIN_ANNOTATION_CHINESE_MERCATOR; mainName = LAYER_NAME_TERRAIN_ANNOTATION_CHINESE; break; } List mainLevelOfDetail = new ArrayList(); Point mainOrigin = null; if(mainIs2000 == true) { for (int i = minZoomLevel; i <= maxZoomLevel; i++) { LevelOfDetail item = new LevelOfDetail(i,RESOLUTIONS_2000[i-1],SCALES[i-1]); mainLevelOfDetail.add(item); } mainEnvelope = ENVELOPE_2000; mainOrigin = ORIGIN_2000; } else { for (int i = minZoomLevel; i <= maxZoomLevel; i++) { LevelOfDetail item = new LevelOfDetail(i,RESOLUTIONS_MERCATOR[i-1],SCALES[i-1]); mainLevelOfDetail.add(item); } mainEnvelope = ENVELOPE_MERCATOR; mainOrigin = ORIGIN_MERCATOR; } mainTileInfo = new TileInfo( DPI, TileInfo.ImageFormat.PNG24, mainLevelOfDetail, mainOrigin, mainOrigin.getSpatialReference(), tileHeight, tileWidth ); webTiledLayer = new WebTiledLayer( mainUrl, SubDomain, mainTileInfo, mainEnvelope); webTiledLayer.setName(mainName); webTiledLayer.loadAsync(); } catch (Exception e) { e.getCause(); } return webTiledLayer; }3、加载天地图
由于天地图是将地图和标注分开的，因此需要加载两个WebTiledLayer对象。
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); ArcGISMap map = new ArcGISMap(tdtBasemap); mapView.setMap(map);
