使用 DialogFragment 和导航库时将对话框显示为全屏或对话框

Question

I have a DialogFragment which consists of a search EditText and a RecyclerView. When you click on a search item, dialog is dismissed and selected item is added to another list in the parent fragment.

I use navigation controller to navigate between fragments. This DialogFragment is currently defined with fragment tag in navigation graph XML. I use findNavController().navigate(destinationId) to open it and findNavController().popBackStack() to close it.

I want to show it as dialog in tablets and full screen on mobile devices but failed to do so.

I tried to create a custom dialog theme whose parent is Theme.MaterialComponents.DayNight.DialogWhenLarge and set it as dialogTheme in the app theme but it overrides attributes in the app theme, like status bar color. I also tried many solutions offered in questions asked here.

How can I achieve this?

<style name="NotificationDialogTheme" parent="android:Theme.Holo.Dialog">
    <item name="android:windowMinWidthMajor">100%</item>
    <item name="android:windowMinWidthMinor">100%</item>
</style>
