No resource identifier found for attribute 'layout_behavior' in package
提问by
My application worked fine until I tried to add a library to it. After I added the library, Android Studio gives me the following error:
在我尝试向其中添加库之前，我的应用程序运行良好。添加库后，Android Studio 给了我以下错误：
Error:(26) No resource identifier found for attribute 'layout_behavior' in package 'inf..'
错误：（26）在包“inf..”中找不到属性“layout_behavior”的资源标识符
This is my build.gradle file:
这是我的 build.gradle 文件：
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:support-v4:23.0.1'
compile 'com.ogaclejapan.smarttablayout:utils-v4:1.3.0@aar'
compile 'com.ogaclejapan.smarttablayout:library:1.3.0@aar'
compile 'com.jpardogo.materialtabstrip:library:1.1.0'
// compile 'com.lorentzos.swipecards:library:1.0.9@aar'
compile 'com.android.support:cardview-v7:21.0.3'
compile 'com.android.support:recyclerview-v7:21.0.3'
compile 'com.melnykov:floatingactionbutton:1.3.0'
compile project(':swipelib')
}
This is the xml which causes the error:
这是导致错误的xml：
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
I tried the following:
我尝试了以下方法：
- Removed the library
- Reset Android Studio and my computer
- Reverted to previous version of my code from git.
- 删除了库
- 重置 Android Studio 和我的电脑
- 从 git 恢复到我的代码的先前版本。
However, the error persists. How do I resolve this?
但是，错误仍然存在。我该如何解决？

That string resource is defined within the Material Design support library.
该字符串资源在 Material Design 支持库中定义。
Since you're not using the CoordinatorLayoutfrom the Material Design support library, you should be able to safely remove the app:layout_behaviorattribute. It was probably cut & paste from other code.
由于您没有使用CoordinatorLayoutMaterial Design 支持库中的 ，您应该能够安全地删除该app:layout_behavior属性。它可能是从其他代码中剪切和粘贴的。
NOTE: If you are actually using CoordinatorLayoutand want the cooperative scrolling behaviors to work, you need to add the dependency for the latest version of the Material Design Support library to your Gradle build file:
注意：如果您实际使用CoordinatorLayout并希望协同滚动行为起作用，则需要将最新版本的 Material Design Support 库的依赖项添加到您的 Gradle 构建文件中：
compile 'com.android.support:design:23.0.1'
UPDATE: Note that with the latest versions of Gradle the compileconfiguration has been deprecated in favor of implementationand apiconfigurations so your dependency could look like this:
更新：请注意，在最新版本的 Gradle 中，compile配置已被弃用，取而代之的是implementation和api配置，因此您的依赖项可能如下所示：
implementation 'com.android.support:design:27.0.2'
This is only an example; the version numbers may be out of date when you read this, so make sure your version matches the version of the support library that you want to use.
这只是一个例子；当您阅读本文时，版本号可能已过时，因此请确保您的版本与您要使用的支持库的版本相匹配。

Note: The versions have changed by now, so replace below versions with the most recent ones.
注意：现在版本已经改变，所以用最新的版本替换下面的版本。
The accepted answer gets rid of the error in case layout_behavior is not needed, however if you actually want to use:
在不需要 layout_behavior 的情况下，接受的答案会消除错误，但是如果您确实想使用：
app:layout_behavior="@string/appbar_scrolling_view_behavior"
Make sure to add the proper dependency to the build.gradle file of your module:
确保将适当的依赖项添加到模块的 build.gradle 文件中：
apply plugin: 'com.android.library'
android {
compileSdkVersion 23
buildToolsVersion "21.1.2"
//Other stuff....
}
dependencies {
//Importing the design library fixes the build
compile 'com.android.support:design:23.1.0'
//Other libraries....
}
I.e. add this line to your dependencies:
即将这一行添加到您的依赖项中：
compile 'com.android.support:design:23.1.0'

Just in case someone else comes from Google and makes the same mistake I did, it's layout_behaviOr, not layout_behavioUr.
以防万一来自 Google 的其他人犯了和我一样的错误，它是layout_behaviOr，不是layout_behavioUr。

AgentKnopf Answer"Make sure to add the proper dependency to the build.gradle file of your module", then I would add, you also make sure the module is same as your current version like this: compile 'com.android.support:design:25.3.1.0if you are not using compile 'com.android.support:design**:23.1.0**'
AgentKnopf 回答“确保将正确的依赖项添加到模块的 build.gradle 文件”，然后我会添加，您还要确保该模块与您当前的版本相同，如下所示：compile 'com.android.support:design : 25.3.1.0如果你没有使用 compile 'com.android.support:design**:23.1.0**'

For those who use AndroidX and don't want to add the old library:
对于那些使用 AndroidX 并且不想添加旧库的人：
com.android.support:design:28.0.0
you can add instead:
你可以添加：
implementation 'com.google.android.material:material:1.0.0'
and use it like this:
并像这样使用它：
app:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior"
