更改微调器项目突出显示颜色

我想将微调器项目高亮橙色更改为蓝色 . 我遵循这个tuturial：http://androidopentutorials.com/android-how-to-get-holo-spinner-theme-in-android-2-x/

在res / drawable-hdpi，res / drawable-mdpi，res / drawable-xhdpi和res / drawable-xxhdpi我有http://android-holo-colors.com/中创建的所有.png文件（以及res / drawable中的.xml文件）

In能够更改微调器背景颜色（当用户点击微调器时）和单选按钮颜色 . 但橙色突出显示颜色（当用户点击对话框上的微调项目时）仍为橙色 .

我做错了什么？
