错误:属性“主题”已被定义

Question

我正在使用Android工作室来构建应用程序。我使用以下依赖项：

1. 播放服务：compile 'com.google.android.gms:play-services:5.2.08'
2. 应用战斗v7：compile 'com.android.support:appcompat-v7:21.0.0'
3. 支持Cardview：compile 'com.android.support:cardview-v7:21.0.0'
4. 支持回收器视图：compile 'com.android.support:recyclerview-v7:21.0.0'

在构建我的应用程序时，我会收到以下错误：

Answer 1

只需使用最新(21)

appCompat和

google播放服务库

例如：

compile 'com.android.support:support-v4:21.0.0'
compile 'com.android.support:appcompat-v7:21.0.0'
compile 'com.android.support:recyclerview-v7:21.0.0' 
compile 'com.android.support:cardview-v7:21.0.0'
compile 'com.google.android.gms:play-services:6.1.11'

那么所有的事情都会发生:)

Answer 2

只要检查一下，您是否有一个名为attrs.xml的文件。在该文件中替换以下行

 <attr name="theme" format="reference" />

使用

 <attr name="apptheme" format="reference" />

也就是说，重命名主题名。现在清理一下这个项目。这解决了我的问题。

Answer 3

在通过SDK管理器更新内容之后，我在Eclipse中也遇到了同样的问题。

我必须从工作区中完全删除Google服务库，然后复制并导入更新后的版本按照这里的说明。

没有更新引用的jars帮助我-只有一个完整的新的导入。这包括更新android-support-v7-appcompat导入。
