我被困了几个小时，找不到一个有效的解决方案（至少不是我的水平），所以我请求你的帮助。再一次。我正在尝试将用户给定的一些值从编辑文本框保存到共享引用。出于某种原因，我接收的不是：1、5或我输入的任何值，而是： view:androidx.appcompat.widget.AppCompatEditText{b869139 VFED..CL. .F....ID 52,0-247,136 #7f0800a1 app:id/etTigPeZi} 同样的java代码也在其他应用程序中使用，而且工作正常。因为某种原因这里没有。我试着找出我可能犯的任何错误，但是，嗯，我没有发现任何错误。请看一看，如果你能救我！
谢谢您。祝大家新年快乐，顺便说一句，r.p。
