现在我正在将 XML 文件中的数据显示到 android 中的网格视图中。这是确切的 xml 文件链接

“ http://54.251.60.177/StudentWebService/StudentDetail.asmx/GetTMSOrders ” 我试图展示。我已经成功地完成了这个概念，但这里的问题是，我没有得到如下图所示的答案

我需要在android中显示如下图

在此处输入图像描述

但我得到的只是下图......

如何克服这个概念？有人可以让我清楚吗？

感谢您宝贵的时间！..

这是我的参考来源，请找到

不要使用网格视图，它不会帮助你。它旨在将项目列表显示为网格。您可以指定列数，但显示表格更像是 TableLayout 的工作。
