void setEntries (CharSequence[] entries)

Sets the human-readable entries to be shown in the list. This will be shown in subsequent dialogs.

See also:

setEntryValues(CharSequence[])

Parameters
`summary`	`CharSequence`: The summary for the preference.

setValue

added in version 24.1.0

void setValue (String value)

Sets the value of the key. This should be one of the entries in getEntryValues().

setValueIndex

added in version 24.1.0

void setValueIndex (int index)

Sets the value to the given index from the entry values.

Parameters
`index`	`int`: The index of the value to set.

Protected methods

onGetDefaultValue

added in version 24.1.0

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`	`TypedArray`: The set of attributes.
`index`	`int`: The index of the default value attribute.

Returns
`Object`	The default value of this preference type.

onRestoreInstanceState

added in version 24.1.0

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

added in version 24.1.0

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

added in version 24.1.0

void onSetInitialValue (boolean restoreValue, 
                Object defaultValue)

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).

In case of using PreferenceDataStore, the restorePersistedValue is always true but the default value (if provided) is set.

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

Parameters
`restoreValue`	`boolean`: True to restore the persisted value; false to use the given `defaultValue`.
`defaultValue`	`Object`: The default value for this Preference. Only use this if `restorePersistedValue` is false.
