How to set DayNight theme for BottomSheetDialog

Question

I'm migrating to the new android DayNight theme.

I've replaced ThemeOverlay.AppCompat.Dark(Light).ActionBar to ThemeOverlay.AppCompat.DayNight.ActionBar

ThemeOverlay.AppCompat.Dark(Light) to ThemeOverlay.AppCompat.DayNight

Everything looks fine. Except that I cannot do the same with BottomSheetDialog. Does DayNight theme exist for BottomSheetDialog?

Answer 1

Yes, try to use Theme.MaterialComponents.DayNight.BottomSheetDialog. For some reason code completion isn't working in Android Studio for that case.

<style name="AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
    ...
    <item name="bottomSheetDialogTheme">@style/Theme.MaterialComponents.DayNight.BottomSheetDialog</item>
</style>

Answer 2

To use the Material Components library you have to use a Material Components Theme

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">

If you can't use it, you should use a Bridge theme in your app:

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar.Bridge">
