Android change text color follow time

We have a TextView and want it change color follow time.

Copy this line of code below.

TexView text = (TextView) findViewById(R.id.textview);

int RED = 0xffFF0000;

int BLUE = 0xff0000FF;

ValueAnimator colorAnim = ObjectAnimator.ofInt(tv, "textColor", RED, BLUE);

colorAnim.setDuration(1000);

colorAnim.setEvaluator(new ArgbEvaluator());

colorAnim.setRepeatCount(ValueAnimator.INFINITE);

colorAnim.setRepeatMode(ValueAnimator.REVERSE);

colorAnim.start();

Press Ctrl+Shift +O to import libraries.

Text color phases will look like this.

To change color faster, reduce value in the line colorAnim.setDuration(1000);

To make it blinking when changing color, edit the line int BLUE to

int BLUE = 0x0000FF;

You can do this for TextView and Button.
