Pass your view and the value of rotation to this method. Hope this will solve your issue.

public void rotateView(final View v, final int rotation) {

    v.animate().setDuration(250).rotation(rotation).setListener(new AnimatorListenerAdapter() {
        @Override
        public void onAnimationStart(Animator animation) {
            super.onAnimationStart(animation);
        }

        @Override
        public void onAnimationCancel(Animator animation) {
            super.onAnimationCancel(animation);
        }

        @Override
        public void onAnimationEnd(Animator animation) {
            super.onAnimationEnd(animation);
        }
    });
}

RotateAnimation rotate = new RotateAnimation(0, 360,
        Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,
        0.5f);

rotate.setDuration(4000);
rotate.setRepeatCount(-1); // here you can set repeatcoount
yourView.setAnimation(rotate)

Hope it will help you.

Cheers!

Oh,I just clear the Rotation Animation that was already applied before applying the new rotation animation.

view.clearAnimation();
