好吧原来，我做了一个非常愚蠢的错误。我使用的测试设备运行的是Android 4.0.4，API级别15。

Okay turned out that I made a really silly mistake. The device I am using for testing is running Android 4.0.4, API level 15.

这是我在编的styles.xml文件在默认值的文件夹。我编辑的价值观V14文件夹中的styles.xml，它工作一切优秀了。

The styles.xml file that I was editing is in the default values folder. I edited the styles.xml in values-v14 folder and it works all fine now.
