如何获取文件夹的子文件而不删除已删除的文件,我的代码如下:

 Drive.Children.List request = children.list("root");
  do
  {
    try
       {
          ChildList cList = request.execute();
          for (ChildReference cr : cList.getItems())
           {
              File file = service.files().get(cr.getId())   .execute();
              System.out.println(file.getTitle() + "--"+ file.getMimeType());
           }
        request.setPageToken(cList.getNextPageToken());
       }
   catch (IOException e)
      {
          System.out.println("An error occurred: " + e);
          request.setPageToken(null);
      }
 } while (request.getPageToken() != null && request.getPageToken().length() > 0);

Answer 1

trashed = false列出时使用查询:

drive.files().list().setQ("trashed = false").execute();

https://developers.google.com/drive/search-parameters上提供了更多查询选项

Answer 2

如果您有多个条件的查询，例如想要获取ROOT的文件和文件夹，并且也不想获取已删除的文件。然后，下面的查询将对“父母的'根'和垃圾桶= false”有所帮助

  request.setQ("'root' in parents and trashed=false").execute();
