Public functions

getText

Added in 1.0.0

fun getText(): String?

Gets the text from the current data storage.

Returns
`String?`	The current preference value

setOnBindEditTextListener

Added in 1.1.0

fun setOnBindEditTextListener(
    onBindEditTextListener: EditTextPreference.OnBindEditTextListener?
): Unit

Set an OnBindEditTextListener that will be invoked when the corresponding dialog view for this preference is bound. Set null to remove the existing OnBindEditTextListener.

Parameters
`onBindEditTextListener: EditTextPreference.OnBindEditTextListener?`	The `OnBindEditTextListener` that will be invoked when the corresponding dialog view for this preference is bound

See also
`EditTextPreference.OnBindEditTextListener`

setText

Added in 1.0.0

fun setText(text: String?): Unit

Saves the text to the current data storage.

Parameters
`text: String?`	The text to save

shouldDisableDependents

fun shouldDisableDependents(): Boolean

Checks whether this preference's dependents should currently be disabled.

Returns
`Boolean`	`true` if the dependents should be disabled, otherwise false

Protected functions

onGetDefaultValue

protected fun onGetDefaultValue(a: TypedArray, index: Int): Any!

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.

Parameters
`a: TypedArray`	The set of attributes
`index: Int`	The index of the default value attribute

Returns
`Any!`	The default value of this preference type

onRestoreInstanceState

protected fun onRestoreInstanceState(state: Parcelable?): Unit

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`.

See also
`onSaveInstanceState`
`restoreHierarchyState`

onSaveInstanceState

protected fun onSaveInstanceState(): Parcelable?

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`.

See also
`onRestoreInstanceState`
`saveHierarchyState`

onSetInitialValue

protected fun onSetInitialValue(defaultValue: Any!): Unit

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: Any!`	The default value for the preference if set, otherwise `null`.
