PreferenceDialogFragment

abstract class PreferenceDialogFragment : DialogFragment, OnClickListener

Known Direct Subclasses EditTextPreferenceDialogFragment, ListPreferenceDialogFragment, MultiSelectListPreferenceDialogFragment EditTextPreferenceDialogFragment ListPreferenceDialogFragment MultiSelectListPreferenceDialogFragment

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.
