Adding Blinking Property to my Custom TextView Class

Hi every one,
i have a Class TextView which draw a simple text on canvas which is extending UiComponent, now i have a requirement to add Text Blink ability to my text view.... We also have Animation Package..
I want to ask what i should do for adding Blinking property to my TextView,
  • I create a new independent class,, and use it in TextView(which is has a relation)
  • My Blink class extend Animation class(because some time i feel Blinking is also a type of Animation)
  • I just add a blink method in my TextView class
please give me any suggestion
