When viewing the Android TV preferences and the built in apps such as YouTube, they appear to use a standard layout as shown here:
I cannot find any examples of implementing preferences on Android TV and can not find the above layouts referenced in any of the LeanBack etc libraries.
Is this a "standard" that I can reuse (like the normal Android PreferenceFragment) or do I have to design my own preference system?
The first image could be duplicated with the LeanBack "BrowseFragment" but the lower one cannot be implemented using anything that I have so far found.
UPDATE
The new support libraries have just been released. All hail GuidedStepFragment
! It should be exactly what you were looking for.
No, unfortunately that view is not provided as a standalone widget in the Leanback library. If you want to take a look for yourself, see here.
It can be implemented quite easily, but alas, you're on your own.
