如何在Kotlin的DatePickerDialog中创建日期分隔符？

<style name="CustomDatePickerDialogStyle" parent="android:datePickerDialogTheme">
    <item name="android:datePickerStyle">@style/CustomDatePickerStyle</item>
</style>

<style name="CustomDatePickerStyle" parent="android:Widget.Material.DatePicker">
    <item name="android:datePickerMode">spinner</item>
    <item name="android:divider">@drawable/custom_divider</item>
    <item name="android:showDividers">middle</item>
</style>

<!-- 自定义分隔符样式 -->
<drawable name="custom_divider">
    <item android:drawable="@color/divider_color" />
    <item android:height="1dp" />
</drawable>

val datePickerDialog = DatePickerDialog(context, R.style.CustomDatePickerDialogStyle, { _, year, month, dayOfMonth ->
    // 日期选择回调
    // 处理选择的日期
}, year, month, day)
