Android Nougat未将日历显示为微调器视图

我在《牛轧糖》（API 24）中遇到了一个问题，即日历并没有显示为旋转器，但直到（API 23）它才正常工作。 我用的是这种风格

<style name="MyDatePicker" parent="android:Widget.Material.DatePicker">
    <item name="android:datePickerMode">spinner</item> 
    <item name="android:calendarViewShown">false</item> 
</style>

假的

尝试将父主题更改为holo，以代替材质主题

<style name="MyDatePicker" parent="android:Theme.Holo.Dark">

我发现的唯一方法是通过XML将其膨胀。我有一个

对话框片段

，下面是适合我的代码：

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">
    <LinearLayout
        android:orientation="vertical" android:layout_width="wrap_content"
        android:layout_height="wrap_content">

        <DatePicker
            android:id="@+id/date_picker"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:datePickerMode="spinner" />

        <Button
            android:id="@+id/ok"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@android:string/ok"
            style="@style/Cerhis.Widget.AppCompat.Button.Base" />

    </LinearLayout>
</layout>
