to RippleDrawable. It will:
1. return the original non-null CSL, unmodified. If null, it will return
a transparent CSL
2. log a warning if the original CSL has a non-transparent pressed color
and a transparent default color for API levels 22-27 (this will cause
ripples to end early).

This will make RippleDrawable work with a single-value ColorStateList as previously it getConstantState().newDrawable() would recreate a MaterialShapeDrawable, losing the logic in RippleDrawableCompat.
