我找不到错误在哪里..我不知道哪些是行和列...也许在 xml 文件中?
这是AndroidManifest文件
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.***">
<application

I had similar issue:
ParseError at [row,col]:[8,279]
Message: http://www.w3.org/TR/1999/REC-xml-names-19990114#AttributeNSNotUnique?androidx.constraintlayout.widget.ConstraintLayout&layout_width&http://schemas.android.com/apk/res/android

What you need to do:
First read the error message carefully, in my case it's mentioned in error message that there is something wrong with:
ConstraintLayout&layout_width attribute in my latest layout xml file.
就我而言,我错误地向标签添加了layout_height和属性,这实际上仅用于数据绑定。因此,只需删除这些行,我就能解决这个问题。layout_width<layout>
我layout最初拥有的:
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">

为了解决这个问题,我做了:
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
