If your are using AppCompact-v7 then you can style PopupMenu as below:

 <style name="AppTheme" parent="Theme.AppCompat.Light">
    <item name="popupMenuStyle">@style/popupMenuStyle</item>
</style>

<style name="popupMenuStyle" parent="Widget.AppCompat.PopupMenu">
    <item name="android:popupBackground">@android:color/white</item>
</style>

NOTE: PopMenu always works with Activity Context, not with Application context.

Add popupMenu style to ur AppTheme:

<style name="AppTheme" parent="android:Theme.Light">
    <item name="android:popupMenuStyle">@style/PopupMenu</item>
</style>

<style name="PopupMenu" parent="@android:style/Widget.PopupMenu">
    <item name="android:popupBackground">@android:color/white</item>
</style>

manifest.xml:

 <application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
.............
</application>
