加入全屏活动Android的工作室后，生成错误 [英] Build errors after adding fullscreen activity in Android Studio

问题描述

我尝试用我的第一次的Hello World般的机器人Studio应用程序。我试图添加一个新的活动（首先通过新建 - > Android的组件，不喜欢的结果，删除它，然后通过新建 - >活动 - >选择全屏活动）。现在，我得到这些错误：

I'm experimenting with my first "Hello World"-like application in Android Studio. I've tried to add a new activity (first via New -> Android Component, didn't like the result, deleted it, then via New -> Activity -> selected Fullscreen activity). Now I get these errors:

  Gradle: Execution failed for task ':LanguagesMemorizer:processDebugResources'.
  > Could not call IncrementalTask.taskAction() on task ':LanguagesMemorizer:processDebugResources'
  C:\...\src\main\res\values\attrs.xml
    Gradle: Attribute "buttonBarStyle" has already been defined
    Gradle: Attribute "buttonBarButtonStyle" has already been defined

我试着在我的项目寻找buttonBarStyle。它被发现在：

I've tried searching for buttonBarStyle in my project. It was found in:

• 建立文件夹（我想我应该忽略，不应该吗？）
• 新的活动布局文件（样式=？buttonBarStyle）
• 在值\ attrs.xml本身（＆LT;申报，设置样式...＆GT;＆LT; attr指示NAME =buttonBarStyle格式=参考/＆GT; ... ）
• 在值\ styles.xml（＆LT;风格...＆GT; ...＆LT;项目名称=buttonBarStyle＆GT; @风格/按钮栏＆LT; /项目＆GT; ... ）
• 值-V11 \ styles.xml（＆LT;风格...＆GT; ...＆LT;项目名称=buttonBarStyle＆GT;安卓？ATTR / buttonBarStyle＆LT; /项目＆GT; .. ）

• build folder (I guess I should ignore that, shouldn't I?)
• layout file for a new activity (style="?buttonBarStyle")
• values\attrs.xml itself (<declare-styleable ...> <attr name="buttonBarStyle" format="reference" /> ...)
• values\styles.xml (<style...>... <item name="buttonBarStyle">@style/ButtonBar</item>...)
• values-v11\styles.xml (<style...>...<item name="buttonBarStyle">?android:attr/buttonBarStyle</item>...)

所有的它是自动生成的。我应该如何解决这个问题？

All of it was auto-generated. How should I fix this error?

更新：有一个在attrs.xml评论它说

UPDATE: There is a comment in attrs.xml which says

<!-- Declare custom theme attributes that allow changing which styles are
         used for button bars depending on the API level.
         ?android:attr/buttonBarStyle is new as of API 11 so this is
         necessary to support previous API levels. -->

所以好像都需要老机器人这些属性，但所以我想有某种API 11-声明的属性和这些手动属性之间存在冲突。我应该如何解决这些问题？

So it seems like these attributes are needed for old Androids, but so I guess there is some sort of a conflict between API 11-declared attributes and these manual attributes. How should I fix them?

推荐答案

这是因为 com.android.support:appcompat-v7:18.0.0 已经有这个属性。所以，如果你打算使用此支持库（你应该）是安全的只是删除声明此属性从项目的\ src \主\水库\值\ attrs.xml 。我想，这样的重复是因为AndroidStudio新的活动向导，不设，您可以使用支持库，所以它本身产生的所有code。

This is because com.android.support:appcompat-v7:18.0.0 already has this attribute. So if you plan to use this support library (and you should) it is safe to just delete declaration of this attributes from your project \src\main\res\values\attrs.xml. I guess, this duplication is because AndroidStudio new activity wizard, doesn't suppose that you can use support library so it generates all code by itself.
