點擊ListView（安卓）項目後mySQL遠程學校服務器

Question

我有一個應用程序，使用Zxing條碼掃描儀掃描庫存資產（電腦，設備） 我可以返回到一個文本字段的條形碼。然後，我可以在窗體上的其他編輯文本字段（description，model，serial＃）中爲該特定掃描資產輸入更多數據。下面的按鈕用於在另一個活動的ListView中將數據保存到我的SQLite數據庫。我想知道，如果我可以點擊列表視圖中的某個項目並將其內容發送到mysql服務器。我似乎在網絡上的一些信息（谷歌），但有沒有人知道任何好的教程或步行通過，可以指導我。

感謝，

Answer 1

要做到這一點，你一般會運行，從您的應用程序接受數據並將其插入到MySQL數據庫的Web服務。您可以使用任何服務器端腳本語言編寫Web服務，但大多數示例都使用PHP。

也許你會找到自己感興趣的Kumulos，它是一個工具，我已經參與了建築，允許您創建這些類型的Web服務並將它們集成到您的移動應用程序中。

我能夠通過將所選項目要做到這一點，以onItemClick基於一些代碼，我在網上找到的，希望這可以幫助任何人仍然在努力解決這個
