Android - 这里是高级Sdk离线地图

Question

我已多次重读文档。但我无法做到这一点我只是想请求你的帮助。

我实现了监听器并以：

开头

MapLoader.Listener mapLoaderListener = new MapLoader.Listener() {
public void onUninstallMapPackagesComplete(MapPackage rootMapPackage,
 MapLoader.ResultCode mapLoaderResultCode) {  
  }
     public void onProgress(int progressPercentage) {
  }
  public void onPerformMapDataUpdateComplete(MapPackage rootMapPackage,
     MapLoader.ResultCode mapLoaderResultCode) {
  }
  public void onInstallationSize(long diskSize, long networkSize) {
  }
  public void onInstallMapPackagesComplete(MapPackage rootMapPackage,
      MapLoader.ResultCode mapLoaderResultCode) {
  }
  public void onGetMapPackagesComplete(MapPackage rootMapPackage,
      MapLoader.ResultCode mapLoaderResultCode) {   // İ put break point and look inside of rootMapPackage to get ids
  }
  public void onCheckForUpdateComplete(boolean updateAvailable,
    String currentMapVersion,String newestMapVersion,
          MapLoader.ResultCode mapLoaderResultCode) {
  }
};

MapLoader mapLoader = MapLoader.getInstance();
mapLoader.addListener(mapLoaderListener);
mapLoader.getMapPackages(); //after this code executed i look inside the
                            //variables in rootMapPackage and i get ids .

mapLoader.installMapPackages(idlist);

在installationMapPackages程序进入

之后

public void onInstallMapPackagesComplete(MapPackage rootMapPackage,
                                        MapLoader.ResultCode mapLoaderResultCode)

根据文档，我认为我应该设法下载并安装地图包以供离线使用，但没有任何反应。安装过程最多需要20秒。所以我觉得没有任何反应。我在互联网上搜索问题，但每个人只是直接向人们提供了这个文档页面，但显然这还不够（至少我没有做到）。流程应该如何？

谢谢
