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'

应用程序构建正常，但我总是收到以下错误:

我已经尝试过版本 4(我以前使用过)和 v7 ActionBarDrawerToggle(更改了构造函数的新格式)，但总是得到相同的错误。应用主题是 Theme.AppCompat.Light.DarkActionBar 的父主题

我真的不知道该看什么。

最佳答案

我在尝试使用 ?attr/selectableItemBackground 时遇到了同样的问题，根据您的回答和在互联网上的一些挖掘，我发现了对我来说有什么问题(可能你也是) .

来自 this answer我了解到“？标记用于引用当前主题中的样式。”这意味着当您使用 ?attr/时，您指的是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而不是在使用 Activity 上下文时才会发生这种崩溃。 This blog post解释“上下文功能”部分中发生的情况。

...[When using the application context] inflation will be done with the default theme for the system on which you are running, not what’s defined in your application.

这意味着 ?attr/将不起作用，因为它们指的是当前主题，而不是您正在使用的默认系统主题。

如果您确保使用 Activity 上下文而不是应用程序上下文进行膨胀，那么 ?attr/可以正常工作。

关于android - 升级到 SDK 21 - 膨胀类 android.support.v7.internal.widget.ActionBarContainer 时出错，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26524048/
