PreferenceDialogFragment

public abstract class PreferenceDialogFragment
extends DialogFragment implements DialogInterface.OnClickListener

java.lang.Object
   ↳ android.app.Fragment
     ↳ android.app.DialogFragment
       ↳ androidx.preference.PreferenceDialogFragment


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.
