Question

我有一个应用程序，我将ActionBar的旧实现更改为ToolBar。为了添加工具栏，我需要使用 Theme.AppCompat.Light.NoActionBar 作为我的基本主题，以便稍后我可以在我的代码中添加ToolBar作为支持的操作栏。但是，此样式/主题在v7_appCompat 19.1.0版中不可用。现在，如果我将appcompat更改为较新的版本iev7：22.1.1，则会抛出以下列表样式，无法解析几乎所有这些样式的符号。

文件名= v21 / values.xml

列表还在继续。我真的不明白为什么会这样。如果我不使用v7的v21或v22，那么我将无法使用 Theme.AppCompat.Light.NoActionBar 样式。但是，如果我在Android Studio中将其更改为较新版本，我将收到上述问题。谁能请帮忙解决这个问题？这张照片怎么了？感谢
