2、基本用法

天地图2000

t_vec = new TianDiTuTiledMapServiceLayer(TianDiTuLayerTypes.VEC_C);
mapView.addLayer(t_vec);
Point initPoint = new Point(121.56, 29.862149);
mapView.zoomToResolution(initPoint, t_vec.getRes()[16]);

百度地图

目前百度地图的图层可以正确加载,但图上坐标偏移很大,需要进一步解决。
BaiduMapsTiledServiceLayer baiduMapsTiledServiceLayer = new BaiduMapsTiledServiceLayer(BaiduMapLayerTypes.BAIDU_VECTOR);
mapView.addLayer(baiduMapsTiledServiceLayer);

final float offsetX = 2518238;
final float offsetY = 910065;

Point curPt = JZLocationConverter.wgs84ToBd09(new Point(121.540614, 29.872488));
Point pt = GISHelper.lonLat2Mercator(curPt);
mapView.zoomToResolution(new Point(pt.getX() + offsetX, pt.getY() + offsetY), GoogleMapsTiledServiceLayer.getRes()[10]);

其它(以Tencent图层为例)

TencentMapsTiledServiceLayer tencentMapsTiledServiceLayer = new TencentMapsTiledServiceLayer(TencentMapLayerTypes.TENCENT_MAP_VECTOR);
mapView.addLayer(tencentMapsTiledServiceLayer);
// 经纬度坐标要转换为GCJ02后,再换成web墨卡托
Point initPoint = JZLocationConverter.wgs84ToGcj02(new Point(121.56, 29.862149));
Point pt = GISHelper.lonLat2Mercator(initPoint);
mapView.zoomToResolution(pt, tencentMapsTiledServiceLayer.getRes()[16]);
