我想加载我的wms服务器,从那里显示瓷砖。我用卡特/ nutiteq和一切都很好,但我想要它的开源或免费许可证。然后我尝试osmdroid库,但我不能实现我的wms任何人都可以帮助我?android mapview与自定义wms瓷砖供应商

// Web Mercator n/w corner of the map. 
private static final double[] TILE_ORIGIN = {-20037508.34789244, 20037508.34789244}; 
//array indexes for that data 
private static final int ORIG_X = 0; 
private static final int ORIG_Y = 1; // 
private static String mLayername = ""; 

// Size of square world map in meters, using WebMerc projection. 
private static final double MAP_SIZE = 20037508.34789244 * 2; 

// array indexes for array to hold bounding boxes. 
protected static final int MINX = 0; 
protected static final int MAXX = 1; 
protected static final int MINY = 2; 
protected static final int MAXY = 3; 
private String layer = "";

你的url中的坐标参考系统EPSG:4326这是纬度/经度wgs84。然而,你看起来像公式从滑动地图坐标转换为EPSG:900913。

您的服务器是否支持CRS?尝试将CRS url参数切换到EPSG:900913或更改公式以计算请求的瓦片的坐标
