升级到SDK 21 - 错误膨胀类android.support.v7.internal.widget.ActionBarContainer

Question

我正在尝试将我的应用从API19升级到API21

我对gradle属性所做的主要更改是:

compileSdkVersion 21
buildToolsVersion "21.0.2"

minSdkVersion 8
targetSdkVersion 21


compile 'com.android.support:appcompat-v7:21.0.0'

该应用程序构建正常,但我总是收到以下错误:

我已经尝试了版本4(我以前使用过)和v7 ActionBarDrawerToggle(对构造函数的新格式进行了更改)但总是得到相同的错误.apps主题是Theme.AppCompat.Light.DarkActionBar的父级

我真的不确定要看什么.

Answer 1

我在尝试使用时遇到了同样的问题?attr/selectableItemBackground并根据你的答案和一些在互联网上挖掘我发现我的错误(也可能是你).

从这个答案中我了解到"？标记用于引用当前主题中的风格." 这意味着当你使用？attr /时,你会引用当前主题中的某些内容.

我注意到,只有在使用应用程序上下文进行膨胀时才会出现此崩溃,而不是在使用活动上下文时.此博客文章解释了"上下文功能"部分中发生的情况.

... [使用应用程序上下文时]通知将使用您运行的系统的默认主题,而不是应用程序中定义的内容.

这意味着？attr /将无法工作,因为它们引用了当前主题,而不是您正在膨胀的默认系统主题.

所以？attr /如果确保使用Activity上下文而不是应用程序上下文进行充气,则工作正常.

Answer 2

我有类似的问题,我正在使用AppCompat.v21并支持Android 5.0.

我的布局对某些值使用了？attr/[attribute_name],我使用了活动上下文.

我把它更改为？android:attr/[attribute_name],现在我的视图在运行Android 5.0的设备上膨胀得很好.

Answer 3

对我来说,当使用值为？attr/format时,问题似乎出现在布局文件中.我不确定它是否与主题相关.我把所有这些都搞定了,然后再添加样式了.
