setAlphadoesn't affect instances ViewGroupin APIs 14 (ICS) -19 (KitKat), even if it was introduced in API level 11. Any ideas why?
I even tried to use the support library, but this does not work either.
Example:
LayoutInflater layoutInflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
ViewGroup view = (ViewGroup) layoutInflater.inflate(R.layout.my_layout, null);
view.setAlpha(0.5f);
It works great for API levels 21+, but not for API levels 14-19.
PS, I have not tested below API level 14.
