I'm trying to implement a Time Duration Selection Spinner for Android TV using Leanback API. The design I'm looking for is somewhat similar to the Date/Time Selection on an Android TV.
I'm looking for a picker with four columns: month, days, hours and seconds. Basically a time duration setter for a timer app.
I understand that this Preference is not available in the current Leanback API. So, I'm looking for advice on how to customise the design. When I go through the source of a Preference such as ListPreference, I don't see any rendering code. So, I'm looking for a nudge in the right direction on how to customise a Preference in Leanback.
