Kotlin |Java

The Preference library allows you to build interactive settings screens, without needing to handle interacting with device storage or managing the user interface.

Interfaces

`DialogPreference.TargetFragment`	Interface for `PreferenceFragmentCompat`s to implement to allow `DialogPreference`s to find the preference that launched the dialog.
`EditTextPreference.OnBindEditTextListener`	Interface definition for a callback to be invoked when the corresponding dialog view for this preference is bound.
`Preference.OnPreferenceChangeListener`	Interface definition for a callback to be invoked when the value of this `Preference` has been changed by the user and is about to be set and/or persisted.
`Preference.OnPreferenceClickListener`	Interface definition for a callback to be invoked when a `Preference` is clicked.
`Preference.SummaryProvider`	Interface definition for a callback to be invoked when the summary of this `Preference` is requested (typically when this preference is added to the hierarchy or its value is updated).
`PreferenceFragment.OnPreferenceDisplayDialogCallback`	Interface that the fragment's containing activity should implement to be able to process preference items that wish to display a dialog.
`PreferenceFragment.OnPreferenceStartFragmentCallback`	Interface that the fragment's containing activity should implement to be able to process preference items that wish to switch to a specified fragment.
`PreferenceFragment.OnPreferenceStartScreenCallback`	Interface that the fragment's containing activity should implement to be able to process preference items that wish to switch to a new screen of preferences.
`PreferenceFragmentCompat.OnPreferenceDisplayDialogCallback`	Interface that the fragment's containing activity should implement to be able to process preference items that wish to display a dialog.
`PreferenceFragmentCompat.OnPreferenceStartFragmentCallback`	Interface that the fragment's containing activity should implement to be able to process preference items that wish to switch to a specified fragment.
`PreferenceFragmentCompat.OnPreferenceStartScreenCallback`	Interface that the fragment's containing activity should implement to be able to process preference items that wish to switch to a new screen of preferences.
`PreferenceGroup.PreferencePositionCallback`	Interface for PreferenceGroup adapters to implement so that `scrollToPreference` and `scrollToPreference` can determine the correct scroll position to request.
`PreferenceManager.OnDisplayPreferenceDialogListener`	Interface definition for a class that will be called when a `Preference` requests to display a dialog.
`PreferenceManager.OnNavigateToScreenListener`	Interface definition for a class that will be called when a `PreferenceScreen` requests navigation.
`PreferenceManager.OnPreferenceTreeClickListener`	Interface definition for a callback to be invoked when a `Preference` in the hierarchy rooted at this `PreferenceScreen` is clicked.
