样式android：应用自定义样式时DatePickerDialog崩溃

Question

我尝试自定义应用对话框样式（包括日期选择器对话框）。

如果我没有指定任何自定义对话框主题，一切正常，但如果我尝试应用自定义主题，则AlertDialog会继续正常工作，而DatePickerDialog会导致我的应用崩溃。

例外情况如下：

我定义了以下样式：

<style name="AppTheme.Dialog" parent="SlidingUpDialog">
    <item name="colorPrimary">?colorPrimary</item>
    <item name="colorPrimaryDark">?colorPrimaryDark</item>
    <item name="colorAccent">?colorAccent</item>
</style>

<style name="SlidingUpDialog" parent="@style/Theme.AppCompat.Light.Dialog">
    <item name="android:windowAnimationStyle">@style/SlidingUpDialogAnimations</item>
</style>

<style name="SlidingUpDialogAnimations">
    <item name="android:windowEnterAnimation">@anim/push_up_in</item>
    <item name="android:windowExitAnimation">@anim/push_up_out</item>
</style>

然后我在App主题（基础）中指定了以下属性：

<style name="AppTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar">

    [...other settings...]

    <item name="android:dialogTheme">@style/AppTheme.Dialog</item>
</style>

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

应用主题v-19是：

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowTranslucentStatus">true</item>
</style>

应用主题v-21是：

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:statusBarColor">@android:color/transparent</item>

    <!-- Transitions -->
    <item name="android:windowContentTransitions">true</item>

    <!-- specify enter and exit transitions -->
    <!-- options are: explode, slide, fade -->
    <!--<item name="android:windowEnterTransition">@android:transition/fade</item>-->
    <!--<item name="android:windowExitTransition">@android:transition/fade</item>-->

    <!-- specify shared element transitions -->
    <!--<item name="android:windowSharedElementEnterTransition">@android:transition/fade</item>-->
    <!--<item name="android:windowSharedElementExitTransition">@android:transition/fade</item>-->
</style>

该配置中缺少什么？ 为什么日期选择器对话框导致上述异常而普通的aler对话框没有？

我想借此机会再问一件事。在样式化时，这三个声明之间有什么区别？

<style name="AppTheme" parent="[STYLE]">
</style>

<style name="AppTheme" parent="@style/[STYLE]">
</style>

<style name="AppTheme" parent="android:[STYLE]">
</style>

此外，在这些之间？

<style name="AppTheme">
   <item name="colorPrimary">@color/colorPrimary</item>
   [...]
</style>

<style name="AppTheme">
   <item name="android:colorPrimary">@color/colorPrimary</item>
   [...]
</style>

编辑：xml布局和java代码

这是打开datepicker对话框的活动的代码片段：

 public void showDatePickerDialog(View v) {
    String currentDate = mBinding.childForm.birthday.getText().toString();

    int[] currentDateParts = LocaleController.getDateParts(currentDate);
    int currYear = currentDateParts[0];
    int currMonth = currentDateParts[1];
    int currDay = currentDateParts[2];

    new DatePickerDialog(context,
            (datePicker, year, monthOfYear, dayOfMonth) -> {
                if(onDateSetAction != null)
                    onDateSetAction.call(year, monthOfYear, dayOfMonth);
    }, currYear, currMonth, currDay).show();
}

这是活动的xml布局文件：

<?xml version="1.0" encoding="utf-8"?>

</data>

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".activity.signup.SignUpActivity">

    <android.support.design.widget.AppBarLayout .../>
        [...]
    </android.support.design.widget.AppBarLayout>

    <ViewFlipper
        android:id="@+id/viewFlipper"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        tools:ignore="UselessParent">

        <include android:id="@+id/child_form"
            layout="@layout/include_signup_form"
            app:viewModel="@{viewModel}" />

        <include android:id="@+id/child_progress"
            layout="@layout/include_progress_full"
            app:status="@{@string/login_progress_signing_up}" />

        <include android:id="@+id/child_complete"
