Xamarin Android - 操作栏图标填充

Question

我已经在我的应用程序中设置了操作栏的样式，但是它在 Android KitKat（右侧设备）和 Android Lollipop（左侧设备）上看起来不同，如图所示：

我想添加一些图标填充（左、右）以使其与 Lollipop 上的相同。任何想法如何修改以下 XML 文件？

资源/值/styles.xml

<?xml version="1.0" encoding="utf-8" ?>
<resources>
  <style name="MyCustomTheme" parent="android:Theme.Holo.Light">
    <item name="android:colorActivatedHighlight">@android:color/transparent</item>
    <item name="android:actionMenuTextColor">@android:color/white</item>
  </style>
</resources>

资源/values-v21/styles.xml

<?xml version="1.0" encoding="utf-8" ?> 
<resources>
    <style name="MyCustomTheme" parent="android:Theme.Material.Light">
      <item name="android:colorActivatedHighlight">@android:color/transparent</item>
      <item name="android:actionMenuTextColor">@android:color/white</item>
      <item name="android:textColorPrimary">@android:color/white</item>
    </style>
</resources>
