我正在尝试为我的大学做这样的事情，用户密码将用户名和密码放入文本框，用户点击登录按钮后，我的应用程序会将登录数据发布到网络服务器URL。成功登录后，我的应用程序webview将显示用户的详细信息。
POST登录数据＆gt;＆gt;到网络服务器＆gt;＆gt; HTML响应＆gt;＆gt; web视图
这是我的完整代码。

这是我的logcat。应用程序运行良好，基于logcat {01-03 01：43：03.587：W / MMU（809）}，我想我已成功发布登录数据，但在运行我的webview时，仍然要求我登录我的用户名和密码。所以我的问题是，我怎么能将我的帖子数据传递给webview？我需要一些帮助......谢谢。
