如何设置一排网格视图中的Android？网格、视图、如何设置、oid

2023-09-06 23:38:48 作者：趁早

现在我展示从XML文件中的数据以android.This网格视图是确切的XML的文件链接

http://54.251.60.177/StudentWebService/StudentDetail.asmx/GetTMSOrders这我试图show.I已经成功地做到这一点的概念，但这里的问题是，我没有得到像下面的图片的答案

我需要表现出像下面的图片，在机器人

但我只得到像下面的图片......

如何克服这个概念？任何一个可以请让我清楚了吗？

感谢您的precious时间！..

下面我的消息来源，以供参考，请找

解决方案

不要使用网格视图，它不会帮你。它的目的是要显示的项目作为一格的列表。可以指定列数，但显示表是更加作业的要TableLayout

Right now i am displaying the data from XML file in to grid view in android.This is the exact xml's file link

"http://54.251.60.177/StudentWebService/StudentDetail.asmx/GetTMSOrders" which i am trying to show.I have done that concept successfully, but here the problem is,i am not getting the answer like the below image

i need to show like the below image, in android

but i am getting only like the below image.....

How to overcome this concept?can any one please make me clear?

thanks for your precious time!..

解决方案

Don't use a grid view, it won't help you. It is designed to display a list of items as a grid. You may specify the number of columns, but displaying a table is more of a job for a TableLayout.
