如果你的 API 是最低 API 级别 14，你可以用这个改变(对我有用)。

<style name="Theme.myapp" parent="@style/Theme.Light.DarkActionBar">
    <item name="android:actionDropDownStyle">@style/myapp_DropDownNav</item>        
    <item name="android:actionBarWidgetTheme">@style/myapp.actionBarWidgetTheme</item>
</style>

<style name="myapp.actionBarWidgetTheme" parent="@style/Theme.">
     <item name="android:spinnerDropDownItemStyle">@style/myapp.Widget.DropDownItem.Spinner</item>
</style>

<style name="myapp_DropDownNav" parent="@style/Widget.Spinner.DropDown.ActionBar">
    <item name="background">@drawable/spinner_background_ab_myapp</item>
    <item name="android:background">@drawable/spinner_background_ab_myapp</item>
    <item name="android:popupBackground">@drawable/menu_dropdown_panel_myapp</item>
    <item name="android:dropDownSelector">@drawable/selectable_background_myapp</item>
</style>

<style name="myapp.Widget.DropDownItem.Spinner" parent="Widget.DropDownItem.Spinner">
    <item name="android:textAppearance">@style/myapp.TextAppearance.Widget.DropDownItem</item>
</style>

<style name="myapp.TextAppearance.Widget.DropDownItem" parent="TextAppearance.Widget.DropDownItem">
    <item name="android:textColor">@color/black</item>
</style>

如果你正在使用 ActionBarSherlock(最低 API 级别 9)，试试这个:

   <style name="Theme.yourapp" parent="@style/Theme.Sherlock.Light">  

    <item name="popupMenuStyle">@style/PopupMenu.Style</item>
    <item name="dropDownListViewStyle">@style/DropDownListView.Style</item> </style>

    <style name="PopupMenu.Style" parent="@style/Widget.Sherlock.Light.ListPopupWindow">    
        <item name="android:popupBackground">@drawable/your_background</item>
    </style>

    <style name="DropDownListView.Style" parent="@style/Widget.Sherlock.Light.ListView.DropDown">
        <item name="android:listSelector">@drawable/your_background</item>
    </style>

希望对你有帮助!!
