我已经得到了一个麻烦，而改变机器人的设计。我需要改变操作栏菜单背景色为黑色。我知道，有很多回答这个问题。我试了很多人。但没有为我工作。

I've got one trouble while changing android design. I need to change action bar menu background color to black. I know, there are lots of answers for this question. I tried many of them. But nothing worked for me.

哦，我忘了说，我不是一个很熟练的Andr​​oid开发者。这是我的风格文件（V21）

添加actionOverflowMenuStyle项目到您的应用程序的主题

add actionOverflowMenuStyle item to your app theme

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="actionOverflowMenuStyle">@style/CMOptionsMenu</item>
    </style>


<style name="CMOptionsMenu" parent="Widget.AppCompat.PopupMenu.Overflow">
     <item name="android:popupBackground">your color code</item>
</style>
