这种方式应该可行。您使用 Popup Window，这就是定义属性的方法：

<style name="Theme.Notes" parent="Theme.MaterialComponents.DayNight">
    <item name="android:popupMenuStyle">@style/PopupMenu</item>
    <item name="android:textAppearanceLargePopupMenu">@style/myPopupMenuTextAppearanceLarge</item>
    <item name="android:textAppearanceSmallPopupMenu">@style/myPopupMenuTextAppearanceSmall</item>
</style>

<style name="PopupMenu" parent="@android:style/Widget.MaterialComponents.PopupMenu">
    <item name="android:popupBackground">@android:color/white</item>
    <item name="android:textColor">#FF01F0</item>
    <item name="android:textSize">12sp</item>
</style>

<style name="myPopupMenuTextAppearanceSmall" parent="@android:style/TextAppearance.DeviceDefault.Widget.PopupMenu.Small">
    <item name="android:textColor">#545656</item>
    <item name="android:textSize">15sp</item>
</style>

<style name="myPopupMenuTextAppearanceLarge" parent="@android:style/TextAppearance.DeviceDefault.Widget.PopupMenu.Large">
    <item name="android:textColor">#545656</item>
    <item name="android:textSize">25sp</item>    
</style>

问题是我通过使用 Theme.MaterialComponents.Dialog.MinWidth 作为对话框父级来使用深色主题对话框，我认为如果我使用深色模式主题就可以了，但我使用的是 Theme .MaterialComponents.DayNight 为应用程序。我只需要将对话框父级更改为 Theme.MaterialComponents.DayNight.Dialog.MinWidth。
