如何在Android中使用nutiteq离线3D地图工作 [英] how to work on offline 3d maps using nutiteq in android

问题描述

我很抱歉，如果这个问题已经被问before.But我越来越麻烦的maps.I已经从GitHub下载源$ C ​​$ C下线的3D工作时：

https://github.com/nutiteq/hellomap3d

其工作良好，但其offlineActivity什么也不会发生，因为我搜索了很多，但没有工作code中的地图不work.Please帮助found.If您有任何的工作code，那么它的高度AP preciated。在此先感谢..！

下面的截图是要求的.nml或.dae file.After选择任一文件.nmldb图像显示（这里的人）上map.If Internet连接上，它显示了3D地图，如果连接处于关闭状态，仅.nml图像显示..

以下是其中我收到错误：

  com.nutiteq.rasterdatasources.HTTPRasterDataSource：加载失败瓦。无法解析主机otile1.mqcdn.com：没有与主机名关联的地址
 DataSourceFetchTask：无瓦片数据
 

这是code这是工作的罚款，如果互联网连接为ON，如果它的关闭，显示上面的错误，我只能得到一个男人的形象，而不地图（screenshot3）：

  RasterDataSource数据源=新HTTPRasterDataSource（新EPSG3857（），0，18日，http://otile1.mqcdn.com/tiles/1.0.0/osm/{zoom}/ {X} / {Y} png格式）;
        RasterLayer mapLayer =新RasterLayer（数据源，0）;
        。mapView.getLayers（）setBaseLayer（mapLayer）;
 

解决方案

继code意味着你使用网上基础地图数据源来自MapQuest的：

  RasterDataSource数据源=新HTTPRasterDataSource（新EPSG3857（），0，18日，http://otile1.mqcdn.com/tiles/1.0.0/osm/{zoom}/ {X} / {Y} png格式）;
 

您应该离线数据源替换它。有不同的选项，请参阅Nutiteq维基页面 https://github.com/nutiteq/ hellomap3d /维基/离线地图 - 瓷砖，在数据源是什么，你可以用AdvancedLayers项目得到的。

I am sorry if this question has been asked before.But I am getting trouble while working on offline 3d maps.I have downloaded the source code from github:

https://github.com/nutiteq/hellomap3d

Its working well but on its offlineActivity nothing happens,the map doesn't work.Please help as i searched a lot but no working code found.If any of you have a working code then its highly appreciated. Thanks in advance.. !

Following screenshot is asking for the .nml or .dae file.After selecting either of the file .nmldb image is shown(here a man) on map.If Internet connection is on,it shows the 3d map and if the connection is off, only the .nml image is shown..

Following are the errors which I am getting:

com.nutiteq.rasterdatasources.HTTPRasterDataSource: failed to load tile. Unable to resolve host "otile1.mqcdn.com": No address associated with hostname
 DataSourceFetchTask: no tile data

This is the code which is working fine if Internet connectivity is ON and if its OFf, the above error is shown and i get only a mans image without the map(screenshot3):

RasterDataSource dataSource = new HTTPRasterDataSource(new EPSG3857(), 0, 18, "http://otile1.mqcdn.com/tiles/1.0.0/osm/{zoom}/{x}/{y}.png");
        RasterLayer mapLayer = new RasterLayer(dataSource, 0);
        mapView.getLayers().setBaseLayer(mapLayer);

解决方案

Following code means that you use online base map data source from MapQuest:

RasterDataSource dataSource = new HTTPRasterDataSource(new EPSG3857(), 0, 18, "http://otile1.mqcdn.com/tiles/1.0.0/osm/{zoom}/{x}/{y}.png");

You should replace it with offline Data Source. There are different options, see Nutiteq wiki page https://github.com/nutiteq/hellomap3d/wiki/Offline-map-tiles for the Data Sources what you can get with AdvancedLayers project.
