SwitchPreferenceCompat 仍然保留了旧的 Switch 样式，我知道可以通过以下方式对其 Material 3 进行样式设置：

主题.xml

<style name="Theme.Material3.Preference" parent="Theme.Material3.DayNight.NoActionBar">\n    <item name="preferenceTheme">@style/MaterialPreferenceThemeOverlay</item>\n</style>\n\n<style name="MaterialPreferenceThemeOverlay" parent="PreferenceThemeOverlay">\n    <item name="switchPreferenceCompatStyle">@style/Preference.SwitchPreferenceCompat</item>\n</style>\n\n<style name="Preference.SwitchPreferenceCompat" parent="Preference.SwitchPreferenceCompat.Material">\n    <item name="android:widgetLayout">@layout/preference_widget_material_switch</item>\n</style>\n

\n但由于某种原因，我必须像这样以编程方式构建 PreferenceFragment：

override fun onCreatePreferences(savedInstanceState: Bundle?, rootKey: String?) {\n\xc2\xa0 \xc2\xa0 val context = preferenceManager.context\n\xc2\xa0 \xc2\xa0 val screen = preferenceManager.createPreferenceScreen(context)\n\xc2\xa0 \xc2\xa0 val notificationPreference = SwitchPreferenceCompat(context).apply {\n        key = …
