- Add a ProgressiveDisclosureMixin that contains all logic for collapse preference list when it's too long - Refactored PreferenceController's updateState to take a preference instead of PreferenceScreen, because with progressive disclosure the preference can either be in screen or the mixin. DashboardFragment is responsible finding the preference before passing it to controller. Bug: 32255863 Test: RunSettingsRoboTests Change-Id: I6713abd61c954ce12732902e5b3ca4d4c0b1563e
