在 OSMDroid 中显示来自 Geoserver 的地图

Question

我已经在 Geoserver 中缓存了图块，我需要在我的 android 应用程序中通过 OSMDroid 显示地图。我已经在我的带有 OpenLayers 的 Web 应用程序中尝试过它并且工作正常，如下所示：

 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。我为自定义图块源创建了 class：

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 class:

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如下：

地理服务器打开地理服务器调试日志后： http://pastebin.com/wTw5ASDC

起初我试过 Mapnik tile source 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 的日志文件中尝试 url，我得到了这个：

当我尝试 url 最后加上“.png”时，我得到了这个：

android 工作室终端打印此：

osmdroid 调用 url 是否可能使用了错误的参数？因为正如您在图片上看到的那样，结构名称略有不同，并且它们包含下划线。

Answer 1

GeoServer 说它不知道如何处理这样的请求：

http://10.0.2.2:8080/geoserver/gwc/service/tms/1.0.0/Bachelor%3Av_slovensko_group@EPSG%3A3857@png/11/9/3

这是因为您没有指定图片格式，所以 URL 这样的应该可以：

http://10.0.2.2:8080/geoserver/gwc/service/tms/1.0.0/Bachelor%3Av_slovensko_group@EPSG%3A3857@png/11/9/3.png
