错误：错误：没有资源的发现，匹配给定的名字：ATTR“buttonBarButtonStyle”

我写在styles.xml文件中的主题，像下面

I write a theme in styles.xml file like below

<?xml version="1.0" encoding="utf-8"?>
<resources>
 <!-- Root styles that vary by API level -->
<style name="FrameworkRoot.Theme" parent="Theme.Sherlock.Light.DarkActionBar">
    <!-- API 11+ (compatibility) -->
    <item name="buttonBarStyle">@style/Compat.ButtonBar</item>
    <item name="buttonBarButtonStyle">@style/Compat.ButtonBarButton</item>
    <item name="indeterminateProgressStyle">@style/Compat.IndeterminateProgress</item>
    <!-- API 14+ (compatibility) -->
    <item name="listPreferredItemPaddingLeft">@dimen/compat_list_preferred_item_padding_left</item>
    <item name="listPreferredItemPaddingRight">@dimen/compat_list_preferred_item_padding_right</item>
    <item name="listPreferredItemHeightSmall">@dimen/compat_list_preferred_item_height_small</item>
</style>

但得到的错误：错误：未发现的资源匹配给定名称：ATTRbuttonBarStyle

but get the error: Error: No resource found that matches the given name: attr 'buttonBarStyle'.

我从谷歌io2012的code。无论井下及其所有基础

I get the code from the google io2012. Both mine and its' all base

    <uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="16" />

我可以编译谷歌io2012源$ C ​​$ C，但不是我的。这么奇怪。 是否有人知道为什么吗？还是有同样的问题？

I can compile the google io2012's source code but not mine. so strange. is anybody know why? or have the same question?
