Why Doesn't This Argument Of The Lineargradient Constructor Seem To Work?

I want to set a custom drawable with a linear gradient as the background drawable of the bar in my SeekBar. I am creating the LinearGradient in the second statement in the followin

Solution 1:

use

ShapeDrawable#setShaderFactory(ShapeDrawable.ShaderFactory factory)

the factory has a method Shader resize(int width, int height) which is called every time your drawable bounds change and this is a place where you should return your LinearGradient shader based on width / height parameters

as you will see you can now just pass null positions and colors will be distributed evenly
