我知道有很多关于这个问题的帖子。然而，它们是基于 Android 3.0 或更高版本构建的(使用 AsyncTask)。我找不到我的解决方案。从网络服务获取信息时出现问题。这是我的代码:

谢谢。

最佳答案

你需要写

string temp= sorgula.getText().toString();

在 try block 中从字符串中获取数据。 同样，您需要提及您在服务器端调用的所有字段。

它对我有帮助。希望对你也有帮助。 :)

关于java - Ksoap2 无法序列化 Android 2.2 上的异常(使用用户定义的对象)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12401494/
