A `https://developer.android.com/reference/kotlin/android/preference/Preference` that displays a list of entries as a dialog.
This preference will store a string into the SharedPreferences. This string will be the value from the `https://developer.android.com/reference/kotlin/android/preference/ListPreference#setEntryValues(kotlin.Array)` array.
## Summary
| XML attributes ||
|---|---|
| [`android:entries`](https://developer.android.com/reference/kotlin/android/preference/ListPreference#attr_ListPreference) | The human-readable array to present as a list. |
| [`android:entryValues`](https://developer.android.com/reference/kotlin/android/preference/ListPreference#attr_ListPreference) | The array to find the value to save for a preference when an entry from entries is selected. |
| Inherited XML attributes ||
|---|---|
| From class `https://developer.android.com/reference/kotlin/android/preference/DialogPreference` |---|---| | `https://developer.android.com/reference/kotlin/android/preference/DialogPreference#attr_DialogPreference` | The icon for the dialog.

| | `https://developer.android.com/reference/kotlin/android/preference/Preference#attr_Preference` | Whether the space for the preference icon view will be reserved. By default, preference icon view visibility will be set to GONE when there is no icon provided, so the default value of this attribute is false. May be a boolean value, such as "`true`" or "`false`".
| | `https://developer.android.com/reference/kotlin/android/preference/Preference#attr_Preference` | The key to store the Preference value. May be a string value, using '\\\\;' to escape characters such as '\\\\n' or '\\\\uxxxx' for a unicode character;
| | `https://developer.android.com/reference/kotlin/android/preference/Preference#attr_Preference` | The layout for the Preference in a PreferenceActivity screen.

| | `https://developer.android.com/reference/kotlin/android/preference/Preference#attr_Preference` | Whether to use single line for the preference title text. By default, preference title will be constrained to one line, so the default value of this attribute is true. May be a boolean value, such as "`true`" or "`false`".
| | `https://developer.android.com/reference/kotlin/android/preference/Preference#attr_Preference` | The summary for the Preference. In API 25 and earlier, this value is read as a plain string with styling information stripped. May be a string value, using '\\\\;' to escape characters such as '\\\\n' or '\\\\uxxxx' for a unicode character;

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 `https://developer.android.com/reference/kotlin/android/content/res/TypedArray.html#getString(kotlin.Int)`.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#onParentChanged(android.preference.Preference,%20kotlin.Boolean)(parent: https://developer.android.com/reference/kotlin/android/preference/Preference!, disableChild: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)` Called when the implicit parent dependency changes.

| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#onSetInitialValue(kotlin.Boolean,%20kotlin.Any)(restorePersistedValue: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html, defaultValue: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-any/index.html!)` Implement this to set the initial value of the Preference. If restorePersistedValue is true, you should restore the Preference value from the `https://developer.android.com/reference/kotlin/android/content/SharedPreferences.html#`. If restorePersistedValue is false, you should set the Preference value to defaultValue that is given (and possibly store to SharedPreferences if `https://developer.android.com/reference/kotlin/android/preference/Preference#shouldPersist()` is true). In case of using `https://developer.android.com/reference/kotlin/android/preference/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.
| | `https://developer.android.com/reference/kotlin/android/os/Bundle.html#!` | `https://developer.android.com/reference/kotlin/android/preference/Preference#peekExtras()()` Return the extras Bundle object associated with this preference, returning `null` if there is not currently one.

This should be unique for the package.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#setLayoutResource(kotlin.Int)(layoutResId: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)` Sets the layout resource that is inflated as the `https://developer.android.com/reference/kotlin/android/view/View.html#` to be shown for this Preference. In most cases, the default layout is sufficient for custom Preference objects and only the widget layout needs to be changed. This layout should contain a `https://developer.android.com/reference/kotlin/android/view/ViewGroup.html#` with ID `https://developer.android.com/reference/kotlin/android/R.id.html#widget_frame:kotlin.Int` to be the parent of the specific widget for this Preference. It should similarly contain `https://developer.android.com/reference/kotlin/android/R.id.html#title:kotlin.Int` and `https://developer.android.com/reference/kotlin/android/R.id.html#summary:kotlin.Int`.

| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#setOnPreferenceClickListener(android.preference.Preference.OnPreferenceClickListener)(onPreferenceClickListener: https://developer.android.com/reference/kotlin/android/preference/Preference.OnPreferenceClickListener!)` Sets the callback to be invoked when this Preference is clicked.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#setOrder(kotlin.Int)(order: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)` Sets the order of this Preference with respect to other Preference objects on the same level. If this is not specified, the default behavior is to sort alphabetically. The `https://developer.android.com/reference/kotlin/android/preference/PreferenceGroup#setOrderingAsAdded(kotlin.Boolean)` can be used to order Preference objects based on the order they appear in the XML.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#setPersistent(kotlin.Boolean)(persistent: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)` Sets whether this Preference is persistent. When persistent, it stores its value(s) into the persistent `https://developer.android.com/reference/kotlin/android/content/SharedPreferences.html#` storage by default or into `https://developer.android.com/reference/kotlin/android/preference/PreferenceDataStore` if assigned.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#setPreferenceDataStore(android.preference.PreferenceDataStore)(dataStore: https://developer.android.com/reference/kotlin/android/preference/PreferenceDataStore!)` Sets a `https://developer.android.com/reference/kotlin/android/preference/PreferenceDataStore` to be used by this Preference instead of using `https://developer.android.com/reference/kotlin/android/content/SharedPreferences.html#`. The data store will remain assigned even if the Preference is moved around the preference hierarchy. It will also override a data store propagated from the `https://developer.android.com/reference/kotlin/android/preference/PreferenceManager` that owns this Preference.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#setRecycleEnabled(kotlin.Boolean)(enabled: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)` Sets whether this Preference has enabled to have its view recycled when used in the list view. By default the recycling is enabled. The value can be changed only before this preference is added to the preference hierarchy. If view recycling is not allowed then each time the list view populates this preference the `https://developer.android.com/reference/kotlin/android/preference/Preference#getView(android.view.View,%20android.view.ViewGroup)` method receives a `null` convert view and needs to recreate the view. Otherwise view gets recycled and only `https://developer.android.com/reference/kotlin/android/preference/Preference#onBindView(android.view.View)` gets called. If you override this method you *must* call through to the superclass implementation.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#setSelectable(kotlin.Boolean)(selectable: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)` Sets whether this Preference is selectable.

For example, set this and `https://developer.android.com/reference/kotlin/android/preference/Preference#setEnabled(kotlin.Boolean)` to false for preferences that are only displaying information and 1) should not be clickable 2) should not have the view set to the disabled state.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#setSingleLineTitle(kotlin.Boolean)(singleLineTitle: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)` Sets whether to constrain the title of this Preference to a single line instead of letting it wrap onto multiple lines.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#setSummary(kotlin.Int)(summaryResId: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)` Sets the summary for this Preference with a resource ID.

| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#setTitle(kotlin.CharSequence)(title: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-char-sequence/index.html!)` Sets the title for this Preference with a CharSequence. This title will be placed into the ID `https://developer.android.com/reference/kotlin/android/R.id.html#title:kotlin.Int` within the View created by `https://developer.android.com/reference/kotlin/android/preference/Preference#onCreateView(android.view.ViewGroup)`.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#setWidgetLayoutResource(kotlin.Int)(widgetLayoutResId: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)` Sets the layout for the controllable widget portion of this Preference. This is inflated into the main layout. For example, a `https://developer.android.com/reference/kotlin/android/preference/CheckBoxPreference` would specify a custom layout (consisting of just the CheckBox) here, instead of creating its own main layout.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#shouldCommit()()` Returns whether the `https://developer.android.com/reference/kotlin/android/preference/Preference` should commit its saved value(s) in `https://developer.android.com/reference/kotlin/android/preference/Preference#getEditor()`. This may return false in situations where batch committing is being done (by the manager) to improve performance. If this preference is using `https://developer.android.com/reference/kotlin/android/preference/PreferenceDataStore` this value is irrelevant.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#shouldDisableDependents()()` Checks whether this preference's dependents should currently be disabled.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#shouldPersist()()` Checks whether, at the given time this method is called, this Preference should store/restore its value(s) into the `https://developer.android.com/reference/kotlin/android/content/SharedPreferences.html#` or into `https://developer.android.com/reference/kotlin/android/preference/PreferenceDataStore` if assigned. This, at minimum, checks whether this Preference is persistent and it currently has a key. Before you save/restore from the storage, check this first.
| | `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html` | `https://developer.android.com/reference/kotlin/android/preference/Preference#toString()()` Returns a string representation of the object.

```
**Deprecated:** *Deprecated in Java.*
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 `https://developer.android.com/reference/kotlin/android/content/res/TypedArray.html#getString(kotlin.Int)`.
| Parameters ||
|---|---|
| `a` | [TypedArray](https://developer.android.com/reference/kotlin/android/content/res/TypedArray.html#)!: The set of attributes. |
| `index` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html): The index of the default value attribute. |

Prepares the dialog builder to be shown when the preference is clicked. Use this to set custom properties on the dialog.
Do not `https://developer.android.com/reference/kotlin/android/app/AlertDialog.Builder.html#create()` or `https://developer.android.com/reference/kotlin/android/app/AlertDialog.Builder.html#show()`.
### onRestoreInstanceState
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
protected open fun onRestoreInstanceState(state: Parcelable!): Unit
```
**Deprecated:** *Deprecated in Java.*
Hook allowing a Preference to re-apply a representation of its internal state that had previously been generated by `https://developer.android.com/reference/kotlin/android/preference/Preference#onSaveInstanceState()`. This function will never be called with a `null` state.
| Parameters ||
|---|---|
| `state` | [Parcelable](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#)!: The saved state that had previously been returned by `https://developer.android.com/reference/kotlin/android/preference/Preference#onSaveInstanceState()`. |

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
protected open fun onSetInitialValue(
restoreValue: Boolean,
defaultValue: Any!
): Unit
```
**Deprecated:** *Deprecated in Java.*
Implement this to set the initial value of the Preference.
If restorePersistedValue is true, you should restore the Preference value from the `https://developer.android.com/reference/kotlin/android/content/SharedPreferences.html#`. If restorePersistedValue is false, you should set the Preference value to defaultValue that is given (and possibly store to SharedPreferences if `https://developer.android.com/reference/kotlin/android/preference/Preference#shouldPersist()` is true).
In case of using `https://developer.android.com/reference/kotlin/android/preference/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 ||
|---|---|
| `restorePersistedValue` | True to restore the persisted value; false to use the given defaultValue. |
| `defaultValue` | [Any](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-any/index.html)!: The default value for this Preference. Only use this if restorePersistedValue is false. |
