現(xiàn)在我正在將數(shù)據(jù)從XML文件顯示到android的網(wǎng)格視圖中.這是xml的確切文件鏈接

“ http://54.251.60.177/StudentWebService/StudentDetail.asmx/GetTMSOrders”其中
我正在嘗試顯示.我已經(jīng)成功地完成了這個概念,但是這里的問題是,我沒有得到下圖所示的答案

我需要在Android中顯示如下圖所示

但是我只得到下面的圖像…..

如何克服這個概念？有人可以讓我說清楚嗎？

感謝您的寶貴時間！..

這里我的參考資料,請找到

解決方法:

不要使用網(wǎng)格視圖,它不會幫助您.它旨在將項目列表顯示為網(wǎng)格.您可以指定列數(shù),但是顯示表對于TableLayout來說是更多的工作.
