Click on the theme selector in the preview window ("MaterialTheme") and select an AppCompat one (or make your theme have that as parent).

The support components won't get rendered unless you select an AppCompat theme. I guess the MaterialTheme is your custom one, so just make sure it uses the appropriate theme as parent.
