## Protected methods

### onGetDefaultValue

```
protected Object onGetDefaultValue(@NonNull 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 `https://developer.android.com/reference/android/content/res/TypedArray.html#getString(int)`.

| Parameters |
|---|---|
| `@https://developer.android.com/reference/androidx/annotation/NonNull https://developer.android.com/reference/android/content/res/TypedArray.html a` | The set of attributes |
| `int index` | The index of the default value attribute |

| Returns |
|---|---|
| `https://developer.android.com/reference/java/lang/Object.html` | The default value of this preference type |

### onRestoreInstanceState

```
protected void onRestoreInstanceState(@Nullable Parcelable state)
```

Hook allowing a preference to re-apply a representation of its internal state that had previously been generated by `https://developer.android.com/reference/androidx/preference/Preference#onSaveInstanceState()`. This function will never be called with a null state.

| Parameters |
|---|---|
| `@https://developer.android.com/reference/androidx/annotation/Nullable https://developer.android.com/reference/android/os/Parcelable.html state` | The saved state that had previously been returned by `https://developer.android.com/reference/androidx/preference/Preference#onSaveInstanceState()`. |

| See also |
|---|---|
| `https://developer.android.com/reference/androidx/preference/Preference#onSaveInstanceState()` |   |
| `https://developer.android.com/reference/androidx/preference/Preference#restoreHierarchyState(android.os.Bundle)` |   |

### onSaveInstanceState

```
protected @Nullable 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 |
|---|---|
| `@https://developer.android.com/reference/androidx/annotation/Nullable https://developer.android.com/reference/android/os/Parcelable.html` | 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 |
|---|---|
| `https://developer.android.com/reference/androidx/preference/Preference#onRestoreInstanceState(android.os.Parcelable)` |   |
| `https://developer.android.com/reference/androidx/preference/Preference#saveHierarchyState(android.os.Bundle)` |   |

### onSetInitialValue

```
protected void onSetInitialValue(Object defaultValue)
```

Implement this to set the initial value of the preference.

If you are persisting values to `https://developer.android.com/reference/android/content/SharedPreferences.html` or a `https://developer.android.com/reference/androidx/preference/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 <var translate="no">defaultValue</var>.

| Parameters |
|---|---|
| `https://developer.android.com/reference/java/lang/Object.html defaultValue` | The default value for the preference if set, otherwise `null`. |
