我重新启动了日食。它的工作现在很好。 问题是sdk没有在我的eclipse中正确加载。

尝试启动eclipse，否则一旦检查你的sdk管理器是否安装了所有东西。

你有没有使用任何片段在XML？请添加名为“android-support-v7-appcompat”的fragmnet支持的库

不，我没有在XML中使用任何片段。每个xml都有同样的问题。 – Siri 2015-03-31 06:48:04

当使用Eclipse和ADT（都是最新版本）时，我遇到了同样的问题。

这看起来像一个ADT的错误，我发现的唯一解决方案（但一个简单的解决方案）只是重新启动Eclipse，然后错误消失。

我得到了同样的错误！当我去下面API 14我GT的错误，否则它工作正常

但我所学到的是....

问题被固定在更新到4.1 SDK，但修复程序尚未回迁到旧版本的布局库 - 但。我相信Xav正在计划这样做以及其他几个已经积累的misc layoutlib修复。

我刚刚得到了同样的错误，并已解决此问题。

我创建了一个新的项目，创建项目后，我的文件AndroidManifest.xml在改变选择的API 21：

android:targetSdkVersion="21"

到

android:targetSdkVersion="22"

谷歌已弃用类ActionBarActivity如果你的'Activity Class'extends那么这个错误发生。

  1. 首先将ActionBarActivity更改为Activity并保存更改。
  2. 然后，重新启动您的IDE并查看错误已修复。

我再次启动我的eclipse，它现在工作正常。在某些情况下，可能会在创建新活动时发生，在这种情况下，您需要删除AndroidManifest.xml文件中的一些访问生成的代码。

我解决它通过改变AndroidManifest.xml中：

android:targetSdkVersion="21"到android:targetSdkVersion="22"

然后换ActionBarActivity到活动。
