How to animate text within a button

Question

I would like to have text within a button blink/pulsate on and off. I know I can use AlphaAnimation to achieve this effect, but from what I know this acts on the entire button view. Is there a way to implement this type of animation on just the text within the button?

Answer 1

You could animate the text color from your standard color to transparent and back again

ObjectAnimator colorAnim = ObjectAnimator.ofInt(myButton, "textColor", Color.RED, Color.TRANSPARENT); 
colorAnim.setDuration(1000); 
colorAnim.setEvaluator(new ArgbEvaluator());     
colorAnim.setRepeatCount(ValueAnimator.INFINITE); 
colorAnim.setRepeatMode(ValueAnimator.REVERSE); 
colorAnim.start();
