自定义字体不适用于棉花糖中的日期选择器

Question

您好我通过反射为整个应用程序设置自定义字体。它的工作正常。但它不适合日期选择器。以下是我的代码。

值-V23

<style name="datepicker" parent="android:Theme.Holo.Light.Dialog">
        <item name="colorPrimary">@color/clr_main</item>
        <item name="colorPrimaryDark">@color/clr_main</item>
        <item name="android:gravity">center</item>
        <item name="android:textAppearance">@android:style/TextAppearance.DeviceDefault.Small</item>
        <item name="android:layout_gravity">center</item>
        <item name="android:background">@null</item>
        <item name="colorAccent">@color/clr_main</item>
        <item name="android:typeface">normal</item>
        <item name="android:datePickerStyle">@android:style/Widget.DatePicker</item>
        <item name="android:calendarViewShown">false</item>
        <item name="android:spinnerMode">dropdown</item>
        <item name="android:fontFamily">fonts/zonapro_regular.otf</item>
        <item name="android:borderlessButtonStyle">@style/date_button_style</item>
        <item name="android:windowBackground">@android:color/white</item>
    </style>


<style name="date_button_style">
        <item name="android:textColor">@color/clr_main</item>
        <item name="android:typeface">normal</item>
        <item name="android:layout_height">35dp</item>
        <item name="android:layout_margin">0dp</item>
        <item name="android:padding">0dp</item>
        <item name="android:textAppearance">?android:textAppearanceSmall</item>
        <item name="android:background">@android:color/transparent</item>
    </style>
