現在、AndroidのグリッドビューにXMLファイルからのデータを表示しています。これは正確なxmlのファイルリンクです。
「http://54.251.60.177/StudentWebService/StudentDetail.asmx/GetTMSOrders」を表示しようとしています。その概念は正常に実行されましたが、ここで問題となるのは、次の画像のような答えが得られないことです。
私はアンドロイドで、以下の画像のように表示する必要があります
しかし、私は下の画像のようになっています.....
この概念を克服する方法は?誰か私にはっきりさせてくれませんか?
貴重な時間をありがとう!..
ここに私の参考資料があります、見つけてください
