this is code

 btn.startAnimation(an);
 an.setAnimationListener(new AnimationListener() {

        @Override
        public void onAnimationStart(Animation animation) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onAnimationRepeat(Animation animation) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onAnimationEnd(Animation animation) {
            // TODO Auto-generated method stub
            iv.startAnimation(an);
            finish();
        }
    });

In your anim folder paste it as a xml

enter code here
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1500"
android:fromDegrees="360"
android:interpolator="@android:anim/linear_interpolator"
android:pivotX="50%"
android:pivotY="50%"
android:repeatCount="infinite"
android:repeatMode="restart"
android:toDegrees="0" />
