添加進度條上傳程序

我做了一個程序，將選定的視頻從SD卡上傳到ASP.NET服務器。現在我想添加一個進度條來顯示上傳文件的狀態？任何人都可以幫我解決這個問題嗎？我有點困惑。我嘗試了很多方式來顯示狀態，但我沒有成功。添加進度條上傳程序

感謝您的幫助。

它顯示在SD卡的文件總數和一個它們上傳到服務器之一，顯示了狀態爲2/20正在上傳進度對話框中。

@Lucifeer感謝您的回覆，但我想添加此欄來實時顯示上傳文件的百分比。你有什麼建議嗎？我會在這裏發佈我的代碼。 – answer88

@ answer88好吧，發佈你的代碼，它可能會幫助我更多地引導你:) – Lucifer

@ answer88：使用AsynTask從服務器下載數據並使用onProgressUpdate根據服務器下載的數據更新進度條 –

如果您打算在通知區域添加進度條，請參閱我的答案：Android: show notification bar on downloading application
