android - 解析 XML 错误重复属性

Question

我尝试了很多解决方案，但都快放弃了。在清理项目、创建新项目或重新导入项目后，我收到两个不断弹出的 xml 解析错误。似乎没有任何效果。它与布局 xml 和一些同名的数据绑定(bind) xml 有关，但它只是不断加载构建文件夹中的数据绑定(bind) xml，它似乎是一个调试位置并给我错误。

这是我的布局 xml:

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">
    <data>
        <variable name="user" type ="com.example.chave.utclinicalnursing.signUpActivity"/>
    </data>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
