我已将主题定义如下。但它不起作用，背景仍然是白色 安卓4.4.2

<style name="BoxTheme" parent="android:Theme.Holo.Light">
        <!-- API 14 theme customizations can go here. -->
        <item name="android:actionBarStyle">@style/BoxActionBar</item>
    </style>
    <style name="BoxActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
            <item name="android:background">@drawable/img_actionbar</item>
             <item name="android:titleTextStyle">@style/colour.Text</item>
              <item name="android:subtitleTextStyle">@style/colour.Text</item>
              <item name="android:popupMenuStyle">@style/PopupMenu</item>
        </style>
    <style name="colour.Text" parent="@android:style/TextAppearance">
            <item name="android:textColor">@color/white</item>
        </style>
        <style name="SpinnerColor" parent="android:style/Widget.Spinner">
            <item name="android:dropDownSelector">@color/white</item>
        </style>
        <style name="PopupMenu" parent="android:style/Widget.Holo.Light.ListPopupWindow">
        <item name="android:popupBackground">@drawable/menu_dropdown_panel</item> 
    </style>

Answer 1

试试这个，

 <style name="AppTheme" parent="AppBaseTheme">
        <item name="android:popupMenuStyle">@style/MyPopupMenu</item>
        <item name="android:panelBackground">@android:color/holo_green_light</item>
        <item name="android:actionBarWidgetTheme">@style/AppTheme</item>
    </style>

    <style name ="MyPopupMenu" parent="android:Theme.Holo.Light">

        <item name="android:popupBackground">@android:color/holo_green_light</item>
    </style>

它可能看起来像这样
