How to implement a custom Shader in Android

Question

I would like to draw a circle filled with blended color with gradient. However, the existing android.graphics.Shader subclasses cannot meet my need. In short, I would like to control the color of each pixel in the circle myself. Is it possible to implement a custom Shadar object by extending android.graphics.Shader?

I am not sure about subclassing android.graphics.Shader

But if you are using OpenGl ES 2.0 you can write your own Shader using GLSL which gives you very high flexibilty.

Maybe have a look at this question.
