Protected methods

onGetDefaultValue

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 TypedArray.getString(int).

Parameters
a TypedArray: The set of attributes

index int: The index of the default value attribute

Returns
Object The default value of this preference type

onRestoreInstanceState

protected void onRestoreInstanceState (Parcelable state)

Hook allowing a preference to re-apply a representation of its internal state that had previously been generated by onSaveInstanceState(). This function will never be called with a null state.

Parameters
state Parcelable: The saved state that had previously been returned by onSaveInstanceState().

onSaveInstanceState

protected Parcelable onSaveInstanceState ()

Hook allowing a preference to generate a representation of its internal state that can later be used to create a new instance with that same state. This state should only contain information that is not persistent or can be reconstructed later.

Returns
Parcelable A Parcelable object containing the current dynamic state of this preference, or null if there is nothing interesting to save. The default implementation returns null.

onSetInitialValue

protected void onSetInitialValue (Object defaultValue)

Implement this to set the initial value of the preference.

If you are persisting values to SharedPreferences or a PreferenceDataStore you should restore the saved value for the preference.

If you are not persisting values, or there is no value saved for the preference, you should set the value of the preference to defaultValue.

Parameters
defaultValue Object: The default value for the preference if set, otherwise null.
