Gradient Radius as percentage of screen size

by

From what I´ve tested, the % does work, but not as you expected.
First of all

android:gradientRadius="50"

seems to take the value as pixels 50px

android:gradientRadius="50%"

is converted as if 50% = 0.5 px, try

android:gradientRadius="5000%"

and you will see a 50px radius.
Using %p has a similar result. Obviously this is something I hope will be changed in the future, because it does not have much use as it is. Usually XML ShapeDrawable resources adapt their size to some external container, in this case gradientRadius is setting the size regardless of the container.
