Protected Methods

protected void onAttachedToHierarchy (PreferenceManager preferenceManager)

Called when this Preference has been attached to a Preference hierarchy. Make sure to call the super implementation.

Parameters

preferenceManager	The PreferenceManager of the hierarchy.

protected void onClick ()

Processes a click on the preference. This includes saving the value to the SharedPreferences. However, the overridden method should call callChangeListener(Object) to make sure the client wants to update the preference's state with the new value.

protected Object onGetDefaultValue (TypedArray a, int index)

Called when a Preference is being inflated and the default value attribute needs to be read. Since different Preference types have different value types, the subclass should get and return the default value which will be its value type.

For example, if the value type is String, the body of the method would proxy to getString(int).

Parameters

a	The set of attributes.
index	The index of the default value attribute.

Returns

The default value of this preference type.

protected void onPrepareRingtonePickerIntent (Intent ringtonePickerIntent)

Prepares the intent to launch the ringtone picker. This can be modified to adjust the parameters of the ringtone picker.

Parameters

ringtonePickerIntent	The ringtone picker intent that can be modified by putting extras.

protected Uri onRestoreRingtone ()

Called when the chooser is about to be shown and the current ringtone should be marked. Can return null to not mark any ringtone.

By default, this restores the previous ringtone URI from the persistent storage.

Returns

The ringtone to be marked as the current ringtone.

protected void onSaveRingtone (Uri ringtoneUri)

Called when a ringtone is chosen.

By default, this saves the ringtone URI to the persistent storage as a string.

Parameters

ringtoneUri	The chosen ringtone's Uri. Can be null.

protected void onSetInitialValue (boolean restorePersistedValue, Object defaultValueObj)

Implement this to set the initial value of the Preference.

If restorePersistedValue is true, you should restore the Preference value from the SharedPreferences. If restorePersistedValue is false, you should set the Preference value to defaultValue that is given (and possibly store to SharedPreferences if shouldPersist() is true).

This may not always be called. One example is if it should not persist but there is no default value given.

Parameters

restorePersistedValue	True to restore the persisted value; false to use the given `defaultValue`.
defaultValueObj	The default value for this Preference. Only use this if `restorePersistedValue` is false.
