You can create an extension in Kotlin :

fun ImageView.rotate(){
val rotateAnimation = RotateAnimation(
    0f, 359f,
    Animation.RELATIVE_TO_SELF, 0.5f,
    Animation.RELATIVE_TO_SELF, 0.5f

)
rotateAnimation.duration = 300
rotateAnimation.setAnimationListener(object : Animation.AnimationListener {
    override fun onAnimationStart(animation: Animation?) {}
    override fun onAnimationRepeat(animation: Animation?) {}
    override fun onAnimationEnd(animation: Animation?) {}
})
this.startAnimation(rotateAnimation)

}
