在OSMDroid中显示地理服务器中的地图

Question

我已经在Geoserver中缓存了瓦片，我需要在我的安卓应用程序中通过OSMDroid显示地图。我已经用OpenLayers在我的web应用程序中尝试了它，并且工作得很好，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。我已经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();
}

}

下面是我的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));
}

}

Geoserver日志打印如下：

geoserver打开geoserver调试日志：http://pastebin.com/wTw5ASDC

首先，我尝试了Mapnik瓦片源码，它工作…但是我不能:/你能告诉我我做错了什么吗？谢谢

编辑:我已经编辑了我的funcition，但仍然不能工作：

@Override
public String getTileURLString(MapTile aTile) {
    return TILE_URL[0] + "/" + aTile.getZoomLevel() + "/" + aTile.getX() + "/" + aTile.getY() + ".png";
}

所以我试着从brwser的日志文件中获取url，得到的结果是：

​

当我尝试在url末尾加上".png“时，我得到的结果是：

​

android studio终端打印如下：

W/OsmDroid: Problem downloading MapTile: /10/651/444 HTTP response: 
W/OsmDroid: Problem downloading MapTile: /10/649/444 HTTP response: 
W/OsmDroid: Problem downloading MapTile: /10/648/445 HTTP response: 
W/OsmDroid: Problem downloading MapTile: /10/650/445 HTTP response: 
W/OsmDroid: Problem downloading MapTile: /10/649/445 HTTP response:

osmdroid是否可能使用错误的参数调用url？因为正如你在图片上看到的，结构名称略有不同，并且它们包含下划线。

Answer 1

GeoServer表示，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像格式，所以像这样的URL应该可以工作：

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