setText或JSON解析不起作用无法弄清楚是什么原因

Question

在这个问题中我试图获取一些输入，然后将它们发布到一个url，然后json解析响应，然后通过textView显示输出，但我的最后一页是空白的.. 我附加了所有的java和xml文件以及日志文件

Answer 1

edob.setText(dob);

你不能直接将int放在textview中。你需要将它转换为一个字符串。

edob.setText(String.valueOf(dob));

如果你用int参数调用setText，android会在资源中寻找一个String的值

Answer 2

设置这样的值。

 efname.setText(""+fname);

通过使用它你也可以设置int值。 所以试试吧。

Answer 3

你试过这个吗？

edob.setText(Integer.toString(dob));
