问题描述

我的应用程序出错，错误提示

 ParseError at [row,col]:[66,34] 消息:http://www.w3.org/TR/1999/REC-xml-names-19990114#AttributeNSNotUnique?Button&layout_column

我找不到错误在哪里..我不知道行和列是哪个...也许在 xml 文件中?

这是 AndroidManifest 文件

 AndroidManifest.xml<?xml version="1.0";编码=utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android";包=com.example.***"><申请android:allowBackup="true";android:icon="@mipmap/ic_launcher";android:label="应用名称"android:roundIcon="@mipmap/ic_launcher_round";android:supportsRtl="true";android:theme="@style/AppTheme"><活动android:name=com.example.appname.MainActivity"android:theme="@style/Theme.AppCompat.NoActionBar";android:screenOrientation="肖像"><意图过滤器><action android:name="android.intent.action.MAIN";/><category android:name="android.intent.category.LAUNCHER";/></意图过滤器></活动><!-- 示例 AdMob 应用 ID:ca-app-pub-3940256099942544~3347511713 --><元数据android:name="appname"android:value=ca-app-pub-2703074771097768~4557375307"/>.</应用程序>

解决方案

我遇到了类似的问题

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

您需要做什么:

首先仔细阅读错误消息，在我的情况下，它在错误消息中提到有问题:ConstraintLayout&layout_width 属性在我最新的布局 xml 文件中.

就我而言，我错误地添加了

<块引用>

layout_height

<块引用>

layout_width

归因于

<块引用>

<布局

标签，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.

要重新生成此问题，请执行以下操作:

为了解决这个问题，我做了:

I have an error with my app the error says

    ParseError at [row,col]:[66,34] Message:         http://www.w3.org/TR/1999/REC-xml-names-19990114#AttributeNSNotUnique?        Button&layout_column 

I can't find where the error is.. I don't know which are the row and col... maybe in the xml files?

This is the AndroidManifest file

    AndroidManifest.xml
    <?xml version="1.0" encoding="utf-8"?>
    <manifest     xmlns:android="http://schemas.android.com/apk/res/android"

        android:label="App Name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

解决方案

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 its mentioned in error message that there is something wrong with: ConstraintLayout&layout_width attribute in my latest layout xml file.

in my case I had mistakenly added

layout_height

layout_width

attributes to

<layout

tag, which is actually meant only for data binding. So just by removing those lines i was able to fix this issue.

TO RE-GENERATE THIS ISSUE DO AS MENTIONED BELOW:

<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">

TO FIX THIS ISSUE I DID:

<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
