我已经在 Geoserver 中缓存了切片，我需要在我的 android 应用程序中通过 OSMDroid 显示地图。我已经使用 OpenLayers 对我的 Web 应用程序进行了尝试，并且可以像这样正常工作：
var map = new ol.Map({
target: 'map',
layers: [
new ol.layer.Tile({
source: new ol.source.XYZ({
url: 'http://localhost:8080/geoserver/gwc/service/tms/1.0.0/Bachelor%3Av_slovensko_group@EPSG%3A3857@png/{z}/{x}/{-y}.png'
})
})
所以现在我需要在 Android 中显示它。我为自定义磁贴源创建了类：
public class GeoserverTileSource extends OnlineTileSourceBase {
public static String[] TILE_URL = {"http://10.0.2.2:8080/geoserver/gwc/service/tms/1.0.0/Bachelor%3Av_slovensko_group@EPSG%3A3857@png"};
public GeoserverTileSource(String aName, int aZoomMinLevel, int aZoomMaxLevel, int aTileSizePixels, String aImageFilenameEnding, String[] aBaseUrl) {
super(aName, aZoomMinLevel, aZoomMaxLevel, aTileSizePixels, aImageFilenameEnding, aBaseUrl);
}
@Override
public String getTileURLString(MapTile aTile) {
return TILE_URL[0] + "/" + aTile.getZoomLevel() + "/" + aTile.getX() + "/" + aTile.getY();
}
}
这是我的 MainActivity 类：
public class MainActivity extends AppCompatActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Context ctx = getApplicationContext();
//important! set your user agent to prevent getting banned from the osm servers
Configuration.getInstance().load(ctx, PreferenceManager.getDefaultSharedPreferences(ctx));
setContentView(R.layout.activity_main);
MapView map = (MapView) findViewById(R.id.map);
GeoserverTileSource source = new GeoserverTileSource("geoserver", 10, 18, 256, ".png", GeoserverTileSource.TILE_URL);
map.setTileSource(source);
//map.setTileSource(TileSourceFactory.MAPNIK);
}
public void onResume(){
super.onResume();
Configuration.getInstance().load(this, PreferenceManager.getDefaultSharedPreferences(this));
}
}
地理服务器日志打印：

geoserver 后打开 geoserver 调试日志： http ://pastebin.com/wTw5ASDC
起初我尝试了 Mapnik 平铺源并且它有效......但我没有：/你能告诉我我做错了什么吗？谢谢
编辑：我已经将我的函数 getTileURLString 编辑为此但仍然无法正常工作：
@Override
public String getTileURLString(MapTile aTile) {
return TILE_URL[0] + "/" + aTile.getZoomLevel() + "/" + aTile.getX() + "/" + aTile.getY() + ".png";
}
所以我在 brwser 中尝试了日志文件中的 url，我得到了这个：
当我最后尝试带有“.png”的url时，我得到了这个：
android studio 终端打印这个：

osmdroid 调用 url 是否可能参数错误？因为正如您在图片上看到的，结构名称略有不同，并且它们包含下划线。
