I'm making a watch face for my android wear watch and in the config activity I want a switch. The switch looks like a usual android switch (picture 1) but I want it to look like the new switchs in android wear 2.0 (picture 2). How did google do them?
The switch in picture 2 is a SwitchPreference which is (at least currently) only supported in a PreferenceFragment.
In the latest update we added a RoundSwitch style which should do exactly what you need.
