Question

我有一个7列15行的表，每个单元格包含一个TextView。我想知道是否有一种方法可以更新单个TextView的内容而无需引用其ID，即可以在表中定位其位置。

我可以使用下面的代码来获取每个单元格的现有值，但是看不到将其修改以更改单元格值的方法。

    public static string DownloadGoogleFile(string fileId)
    {
        Google.Apis.Drive.v3.DriveService service = GetService_v3();

        string FolderPath = System.Web.HttpContext.Current.Server.MapPath("/GoogleDriveFiles/");
        Google.Apis.Drive.v3.FilesResource.GetRequest request = service.Files.Get(fileId);
        string FileName = request.Execute().Name;
        string FilePath = System.IO.Path.Combine(FolderPath, FileName);

        MemoryStream stream1 = new MemoryStream();

        // Add a handler which will be notified on progress changes.
        // It will notify on each chunk download and when the
        // download is completed or failed.
        request.MediaDownloader.ProgressChanged += (Google.Apis.Download.IDownloadProgress progress) =>
        {
            switch (progress.Status)
            {
                case DownloadStatus.Downloading:
                    {
                        Console.WriteLine(progress.BytesDownloaded);
                        break;
                    }
                case DownloadStatus.Completed:
                    {
                        Console.WriteLine("Download complete.");
                        SaveStream(stream1, FilePath);
                        break;
                    }
                case DownloadStatus.Failed:
                    {
                        Console.WriteLine("Download failed.");
                        break;
                    }
            }
        };
        request.Download(stream1);
        return FilePath;
    }

您的函数getCellAtPos返回一个View对象。您只需将其类型转换为TextView对象，因为View没有setText（）方法。

    TextView tv=(TextView)getCellAtPos(table,pos);
    tv.setText("abc");
