无法覆盖AppCompat PopupMenu

Question

我只是想为PopupMenu使用覆盖样式。

我将它附加到我的整体风格

<style name="MyTheme" parent="Theme.AppCompat.Light">
  <item name="colorAccent">@color/red</item>
  <item name="colorPrimary">@color/red</item>
  <item name="colorPrimaryDark">@color/red</item>
  <item name="android:colorBackground">@color/red</item>
  <item name="android:windowBackground">?android:attr/colorBackground</item>
  <item name="android:textColorPrimary">@color/black</item>
  <item name="android:alertDialogTheme">@style/AlertDialogStyle</item>
  <item name="android:popupMenuStyle">@style/PopupMenuStyle</item>  
  <item name="android:spinnerDropDownItemStyle">@style/Widget.AppCompat.DropDownItem.Spinner</item>
</style>

这是风格

<style name="PopupMenuStyle" parent="Theme.AppCompat.Light.PopupMenu">
  <item name="android:background">@color/white</item>
</style>

无法找到父母。我需要哪位家长？
