LeanbackPreferenceFragment

abstract class LeanbackPreferenceFragment : BaseLeanbackPreferenceFragment
kotlin.Any
   ↳ android.app.Fragment

   ↳ androidx.leanback.preference.LeanbackPreferenceFragment

This fragment provides a fully decorated leanback-style preference fragment, including a list background and header.

The following sample code shows a simple leanback preference fragment that is populated from a resource. The resource it loads is:

{@sample frameworks/support/samples/SupportPreferenceDemos/src/main/res/xml/preferences.xml preferences}

The fragment needs only to implement onCreatePreferences(Bundle, String) to populate the list of preference objects:

{@sample frameworks/support/samples/SupportPreferenceDemos/src/main/java/com/example/androidx/preference/LeanbackPreferences.java leanback_preferences}
