            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="@String/continue_label"/>

推荐答案

可能有两种情况-

情况1-如果在第一条语句前有空格。

case 1 - If you have an empty space before the first statement.

情况2-如果您不小心两次输入了相同的namepacing语句，即-？xml version = 1.0 encoding = utf-8？

case 2 - If you have accidently put the same namespacing statement twice ie - ?xml version="1.0" encoding="utf-8"?

我做了一次，并在更正它后遇到了与您相同的错误，我的代码运行正常。希望对您有帮助

I did it once and landed with the same error of yours after correcting it my code runs fine. hope this helps
