<!-- android:elevation:
1. Needs to match the speed dial's minimal elevation,
or the speed dial can't be clicked at all
2. It is honored for API >= 21, but it does not hurt to be added here.
Use tools:ignore to suppress warnings.
Otherwise, we need a custom layout for API >= 21 that is more difficult to maintain.
