how to add gradient to my rectangle shape dynamically in android?

I have created re开发者_开发百科ctangle shapes using onDraw method, filled with single colors. Now I have a requirement to add gradient effects to those rectangles. Now I have to fill each rectangle with multiple colors(i.e gradient effect). Could some one suggest me the way to do that. Any response would be great.

thanks in advance.
