Text color animation

Question

Is there a way to animate a text color change (from anycolor to white)?

The only variant I came up with, is placing two textviews (with the same text) in one place,

Answer 1

As others mention, using ObjectAnimator solves for this. However, in the existing posts - I wasn't seeing how to set duration. For me the color change would happen immediately.

The solution below shows:

1. setting the animation with some interval; thanks to post: https://plus.google.com/+CyrilMottier/posts/X4yoNHHszwq

2. a way to continuously cycle back and forth between the 2 colors

void animateTextViewColors(TextView textView, Integer colorTo) {

    final Property property = new Property(int.class, "textColor") {
        @Override
        public Integer get(TextView object) {
            return object.getCurrentTextColor();
        }

        @Override
        public void set(TextView object, Integer value) {
            object.setTextColor(value);
        }
    };

    final ObjectAnimator animator = ObjectAnimator.ofInt(textView, property, colorTo);
    animator.setDuration(8533L);
    animator.setEvaluator(new ArgbEvaluator());
    animator.setInterpolator(new DecelerateInterpolator(2));
    animator.start();
}

void oscillateDemo(final TextView textView) {

    final int whiteColor = ContextCompat.getColor(TheApp.getAppContext(), R.color.white);
    final int yellowColor = ContextCompat.getColor(TheApp.getAppContext(), R.color.yellow);

    final int counter = 100;

    Thread oscillateThread = new Thread() {
        @Override
        public void run() {

            for (int i = 0; i < counter; i++) {

                final int fadeToColor = (i % 2 == 0)
                        ? yellowColor
                        : whiteColor;

                getActivity().runOnUiThread(new Runnable() {
                    @Override
                    public void run() {

                        animateTextViewColors(textView, fadeToColor);
                    }
                });                                      

                try {
                    Thread.sleep(2450);
                }
                catch (InterruptedException iEx) {}
            }
        }
    };

    oscillateThread.start();
}
