Theme customizations available in newer API levels can go in
res/values-vXX/styles.xml, while customizations related to
backward-compatibility can go here.
-->

You are trying to use Theme.AppCompat.Lighttheme which is a library project. You have to reference this library project to your project.
您正在尝试使用Theme.AppCompat.Light主题，这是一个库项目。您必须将此库项目引用到您的项目中。
Now, at first, check that you have installed this library project as follows...
现在，首先，检查您是否已经安装了这个库项目，如下所示......
Go Window-->Android SDK Managerthen a window named Android SDK Managerwill appear as below.
Go Window--> Android SDK Manager然后会出现一个名为Android SDK Manager的窗口，如下所示。
If the Android Support Libraryis not installed then install it. You can see more information about Android Support Librarysetup from the below Android Developer site.
如果Android Support Library未安装，则安装它。您可以Android Support Library从下面的 Android 开发人员站点查看有关设置的更多信息。
After Android Support Librarysetup completion, reference the library to your project from this path...
后Android Support Library安装完成后，引用该库到您的项目从此路径...
android-sdk/extras/android/support/v7/appcompat
To reference, follow these steps:
要参考，请按照下列步骤操作：
- File->Import(android-sdk\extras\android\support\v7). Choose "appcompat"
- Project-> properties->Android. In the section library "Add" and choose "appCompat"
- 文件->导入（android-sdk\extras\android\support\v7）。选择“ appcompat”
- 项目->属性-> Android。在部分库中“添加”并选择“ appCompat”
Now, clean and build your project and run it. I think after all of these, your problem will be solved.
现在，清理并构建您的项目并运行它。我想在所有这些之后，您的问题将得到解决。

Since you're using Theme.AppCompat.Lightin your Theme, you have to include appCompatinto your Project.
由于您Theme.AppCompat.Light在主题中使用，因此必须包含appCompat到您的项目中。
File->Import (android-sdk\extras\android\support\v7). Choose "appcompat"
Project-> properties->Android. In the section library
"Add" and choose "appCompat"
文件->导入（android-sdk\extras\android\support\v7）。选择“应用兼容”
项目-> 属性-> Android。在截面库中
“添加”并选择“appCompat”
That should work.
那应该工作。

确保你<resources>正确关闭了标签并在你的styles.xml 底部添加：
</resources>
according to your posted code snippet that is not present, but needs to be
根据您发布的不存在的代码片段，但需要
Edit: the missing resources tag was just a copy-paste bug in question, so here that was not the reason.
编辑：缺少的资源标签只是一个有问题的复制粘贴错误，所以这不是原因。
