public abstract class PreferenceDialogFragmentCompat
extends DialogFragment implements DialogInterface.OnClickListener

       ↳ androidx.preference.PreferenceDialogFragmentCompat

Abstract base class which presents a dialog associated with a DialogPreference. Since the preference object may not be available during fragment re-creation, the necessary information for displaying the dialog is read once during the initial call to onCreate(Bundle) and saved/restored in the saved instance state. Custom subclasses should also follow this pattern.
