Android 如何在sherlock操作栏中覆盖按下的状态颜色？

我在我的应用程序中实现了sherlock actionbar，它有深绿色的操作栏。。 #当我按下操作栏按钮时，它会变成蓝色（默认）颜色…当我按下操作栏按钮时，如何变成绿色

       <resources>
<style name="Theme.Styled" parent="Theme.Sherlock.Light">
    <item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>
    <item name="android:actionBarStyle">@style/Widget.Styled.ActionBar</item>
 <item name="actionBarItemBackground">@drawable/selector</item>
</style>
<style name="Widget.Styled.ActionBar" parent="Widget.Sherlock.Light.ActionBar.Solid.Inverse">
    <item name="background">#008000</item>
    <item name="android:background">#008000</item>

    <item name="backgroundSplit">@drawable/bg_striped_split</item>
    <item name="android:backgroundSplit">@drawable/bg_striped_split</item>


</style>

在themes.xml中，我使用了这个

       <resources>
<style name="Theme.Styled" parent="Theme.Sherlock.Light">
    <item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>
    <item name="android:actionBarStyle">@style/Widget.Styled.ActionBar</item>
 <item name="actionBarItemBackground">@drawable/selector</item>
</style>
<style name="Widget.Styled.ActionBar" parent="Widget.Sherlock.Light.ActionBar.Solid.Inverse">
    <item name="background">#008000</item>
    <item name="android:background">#008000</item>

    <item name="backgroundSplit">@drawable/bg_striped_split</item>
    <item name="android:backgroundSplit">@drawable/bg_striped_split</item>


</style>

@style/Widget.Styled.ActionBar
@style/Widget.Styled.ActionBar
@可牵引/选择器
#008000

@可拉伸/背景条纹分割

在drawable selector.xml中

       <resources>
<style name="Theme.Styled" parent="Theme.Sherlock.Light">

    <item name="backgroundSplit">@drawable/bg_striped_split</item>
    <item name="android:backgroundSplit">@drawable/bg_striped_split</item>


</style>

<item android:state_pressed="true" android:drawable="@drawable/pressed" />
<item android:state_focused="true" android:drawable="@drawable/focused" />
<item android:drawable="@android:color/transparent" />
