升级到SDK 21 - 错误充气类android.support.v7.internal.widget.ActionBarContainer [英] Upgrading to SDK 21 - Error inflating class android.support.v7.internal.widget.ActionBarContainer

问题描述

我想从API19升级我的应用程序API21

I'm trying to upgrade my app from API19 to API21

我所做的摇篮性能的主要变化是：

The main changes I've made to the gradle properties are:

compileSdkVersion 21
buildToolsVersion "21.0.2"

minSdkVersion 8
targetSdkVersion 21


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

该应用程序构建好了，但我总是得到以下错误：

The app builds ok, but I always get the following error:

我已经试过了第4版（我是用previously）和V7 ActionBarDrawerToggle（有变化的新格式的构造函数），但总是得到同样的错误。该应用程序的主题是Theme.AppCompat.Light.DarkActionBar的父

I've tried the version 4 (which I was using previously) and the v7 ActionBarDrawerToggle (with a change to the new format for the constructor) but always get the same error. The apps theme is a parent of Theme.AppCompat.Light.DarkActionBar

我真的不知道看什么。

推荐答案

我不得不尝试使用时，同样的问题？ATTR / selectableItemBackground 并根据您的答案和一些在互联网上周围挖我发现了什么是错误的，我（也许你也一样）。

I had the same problem when trying to use ?attr/selectableItemBackground and based on your answer and some digging around on the internet I found out what was wrong for me (and probably you as well).

从这个答案我了解到，？标记用来引用样式当前主题。这意味着，当你使用？ATTR /你是指一些在当前的主题。

From this answer I learned that "? mark is used to reference style in current theme." Which means that when you use ?attr/ you refer to something in the current theme.

我注意到，我使用的应用程序环境和不使用活动的背景下，当充气时，得到这个崩溃而已。 本博客文章解释正在发生的事情上下文能力一节。

I noticed that I got this crash only when inflating using the application context and not when using the activity context. This blog post explains what's happening in "Context Capabilities" section.

... [使用应用程序上下文]通胀将与完成   默认主题要在其上运行的系统，而不是什么   在应用程序中定义的。

...[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 /将无法工作，因为它们指的是当前的主题，而不是默认的系统主题，你正在用充气

This mean that ?attr/ won't work since they refer to the current theme, not the default system theme you're inflating with.

所以？ATTR /如果您确保使用活动方面，而不是应用程序上下文膨胀工作正常。

So ?attr/ works fine if you make sure to inflate using the Activity context instead of the application context.
