Update Attributes during Rotation Animation

Question

I\'m working on a rotation animation in Kotlin and I after each Animation I want to set a net rotationStart and rotationEnd where the rotationStart value initially should be set

Answer 1

Well, the only way I found until now is this here (just in case nobody will answer to this thread, here is my solution)

    val angles = arrayOf(9,6,9,4)

    var rotStart = 0f
    var imageSpinner = findViewById<ImageView>(R.id.img_spinner)

        val ra1 = RotateAnimation(rotStart,-angles[0].toFloat() * 39, Animation.RELATIVE_TO_SELF, 0.5f,
                Animation.RELATIVE_TO_SELF, 0.5f)
    ra1.duration = 3200

    val ra2 = RotateAnimation(rotStart, -angles[1].toFloat() * 39, Animation.RELATIVE_TO_SELF, 0.5f,
            Animation.RELATIVE_TO_SELF, 0.5f)
    ra2.duration = 1900
       val ra3 = RotateAnimation(rotStart, -angles[2].toFloat() * 39, Animation.RELATIVE_TO_SELF, 0.5f,
            Animation.RELATIVE_TO_SELF, 0.5f)
    ra3.duration = 5400
    val ra4 = RotateAnimation(rotStart, -angles[3].toFloat() * 39, Animation.RELATIVE_TO_SELF, 0.5f,
            Animation.RELATIVE_TO_SELF, 0.5f)
    ra4.duration = 5400

after this you have to set on each onAnimationEnd: imageview.startAnimation(ra#NUMBER#). It's a workaround and not a clean solution :-)
