使用多个主题时未应用DialogFragment标题文本

Question

我尝试在我的DialogFragment上设置标题文字，但它没有按照我的预期运作。唯一有效的是，如果onCreate() dialogFragment明确地这样做：

setStyle(DialogFragment.STYLE_NORMAL, MyStyl...............);

并以那种风格设置了

    <item name="android:windowNoTitle">false</item>

但我有多个主题，用户可以在运行时更改为主题，所以我喜欢这样设置DialogFragment主题。

    <android.support.constraint.ConstraintLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:srcCompat="http://schemas.android.com/tools"
        android:id="@+id/place_search_dialog"
        style="?alertDialogTheme"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:visibility="visible">

但是现在即使我在alertDialogTheme属性中设置了"android:windowNoTitle">false</item>，标题文本也没有显示， 为什么会这样？
