Error parsing XML: duplicate attributes?
提问by user3442610
I'm having trouble setting the background for my button. I tried setting it to
我在为我的按钮设置背景时遇到问题。我尝试将其设置为
android:background="@drawable/mybutton_background"
but that caused an error, saying "String types not allowed"referring to "@drawable/mybutton_background". It also caused another error causing me to lose my R.javafile and giving me the "R cannot be resolved into a variable error". I just gave up on the button and deleted the background, but the error remained after it was deleted. Well, that error is now gone and I now get a message that says Error parsing XML: duplicate attributes for one line of code, but once I delete that line, the error message moves on to another line! It's like Eclipse won't update to realize I deleted that line of code. I checked for updates and cleaned my project countless times, but I'm still getting the same error. Does anyone know what's up with my project?
但这导致了一个错误，说"String types not allowed"是指"@drawable/mybutton_background"。它还导致另一个错误，导致我丢失R.java文件并给我"R cannot be resolved into a variable error". 我只是放弃了按钮并删除了背景，但删除后错误仍然存在。好吧，那个错误现在消失了，我现在收到一条消息，上面写着 Error parsing XML: duplicate attributes for one line of code，但是一旦我删除了该行，错误消息就会移到另一行！这就像 Eclipse 不会更新以意识到我删除了那行代码。我无数次检查更新并清理我的项目，但我仍然遇到同样的错误。有谁知道我的项目是怎么回事？

In my case this error was due to duplicate xmlns attributes inside layout. If you have something like this:
在我的例子中，这个错误是由于布局中重复的 xmlns 属性造成的。如果你有这样的事情：
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">
<data>
<variable
name="person"
type="com.abc.PersonEntity" />
</data>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
...
Remove the xmlns attribute from the second layout:
从第二个布局中删除 xmlns 属性：
<LinearLayout
...

From the parent RelativeLayoutXMl android:background="android:background=""or update it with a drawable or with color as android:background="#FFFF00"
从父RelativeLayoutXMLandroid:background="android:background=""或使用可绘制或颜色更新它android:background="#FFFF00"
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="android:background="" <---remove this or update with correct drawable
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin" >
In this below ButtonXML, you have added android:backgroundattribute 2 times...Which causing the problem.
在下面的ButtonXML 中，您添加了android:background2 次属性......这导致了问题。
<Button
android:background="@drawable/" <-----first time
android:id="@+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/imageView1"
android:layout_alignLeft="@+id/imageView1"
android:layout_marginBottom="17dp"
android:background="@drawable/mybutton_background" <-----second time
android:focusableInTouchMode="true"
android:text="Enlighten me!"
android:textColor="#3f0f7f"
android:textSize="32sp"
android:textStyle="bold|italic"
android:typeface="serif"
android:visibility="visible" />
Now, remove the first one...your problem will be solved.
现在，删除第一个……您的问题将得到解决。

You have the attribute background repeated
你有重复的属性背景
android:background="@drawable/"
android:id="@+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/imageView1"
android:layout_alignLeft="@+id/imageView1"
android:layout_marginBottom="17dp"
android:background="@drawable/mybutton_background" <----- where I get the error

android:background="android:background=""<--quot; remove code here
android:background="android:background=""<--quot; remove code here
Look at this line in your parent relative layout. Just remove the background from here. Because of this line it causes "String types not allowed".
在您的父级相对布局中查看这一行。只需从这里删除背景。由于这一行，它会导致“不允许字符串类型”。
And second problem in below Button XML, you have added android:background2 times...Which causing "Error parsing XML: duplicate attributes for one line of code".So just remove one background.
下面的 Button XML 中的第二个问题，你已经添加了android:background2 次......这导致了"Error parsing XML: duplicate attributes for one line of code".所以只需删除一个背景。
enter code here
在此处输入代码

In my case xmlns:android = "http://schemas.android.com/apk/res/android"was missing in one of the manifests. In integrated debug manifest file this attribute is shown twice. Adding this attribute to each amnifest (even an empty one) solved the problem.
在我的情况下xmlns:android = "http://schemas.android.com/apk/res/android"，其中一个清单中缺少。在集成调试清单文件中，此属性显示两次。将此属性添加到每个 amnifest（甚至是空的）解决了这个问题。

In my case error was due to 2 id's android:id="@+id/layout" ( id) and android:id="@+id/parent" (Linear layout id)
在我的例子中，错误是由于 2 id 的 android:id="@+id/layout" ( id) 和 android:id="@+id/parent" (Linear layout id)
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/layout"
android:background="@color/plain_background">
<LinearLayout
android:id="@+id/parent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
</LinearLayout>
