我一直试图让这个工作好几天。
当我上传音频文件时，如何获取用户名以发布到PHP文件？
在我的Loggedin活动中，用户在我的JoinView活动传递的文本字段中显示了uername。作品。我正在录制一段时间，当用户点击一个按钮时，一旦录制完成，它就会将文件发布到服务器。在我开始之前也有效。我在将Uploads.php文件的用户名获取时遇到问题。 Upload方法在我的Upload.java类中。从Loggedin活动调用。所以，我不认为我的用户名会被发布到php文件中。不确定。
这是我的LoggedIn活动。

我不认为我得到了usernamepush到php文件。就像我说的那样，它被传递给LoggedIn Activity并显示给用户。
请帮助。
