是否可以将弹出菜单样式从白色背景上的默认黑色文本更改为深色背景而不将样式应用于整个活动(这会破坏我的UI)？

我试图改变popupmenu的背景,但我的实现不起作用.

这是我的代码:

<style name="MyHoloLight" parent="android:Theme.Holo.Light">
    <item name="android:popupMenuStyle">@style/popupMenuStyle</item>
</style>
<style name="popupMenuStyle" parent="@android:style/Widget.PopupMenu">
    <item name="android:popupBackground">@color/bgPopumMenu</item>
</style>

在AndroidManifest.xml中应用

<application
        android:hardwareAccelerated="true"
        android:label="@string/app_name"
        android:icon="@drawable/ic_launcher"
        android:theme="@style/MyHoloLight">

我使用了 app compat theme style 。

  <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="android:popupMenuStyle">@style/PopupMenu</item>
        <item name="android:itemTextAppearance">@style/myCustomMenuTextApearance</item>
        <item name="android:listPopupWindowStyle">@style/PopupMenuStyle</item>

    </style>
    <style name="PopupMenuStyle" parent="Widget.AppCompat.ListPopupWindow">
        <item name="android:divider">@drawable/devider</item>
        <item name="android:dividerHeight">2dp</item>
    </style>

    <style name="PopupMenu" parent="@android:style/Widget.PopupMenu">
        <item name="android:popupBackground">@color/search_panel_color</item>
        <item name="android:textColor">@color/activity_button_text_color</item>
        <item name="android:shadowColor">@color/activity_theam_color</item>


    </style>

    <style name="myCustomMenuTextApearance" parent="@android:style/TextAppearance.Widget.TextView.PopupMenu">
        <item name="android:textColor">@color/activity_theam_color</item>
    </style>

我想在我的菜单项中添加一个分隔符。我尝试了很多东西，但分隔线不适用......有没有办法显示分隔线？
