Android Studio repeatable Fade Animation to ImageView on Button Click

Question

I´m new to programming, started in the Lockdown last year with youtube videos and a book. I´m trying to make a button, that starts an fade out animation on an ImageView. which should be repeatable. It´s basically a dice roll and i want the dice to appear and then disappear every time within like 2 seconds after click.

Animation animation = AnimationUtils.loadAnimation(getApplicationContext(),R.anim.fade_out);
    dice.setAnimation(animation);
    animation.setStartOffset(3000);
    animation.setDuration(100);

    dice.setVisibility(View.VISIBLE);
    dice.animate().alpha(1).setDuration(500);
    btnDice.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Animation animation1 =AnimationUtils.loadAnimation(getApplicationContext(),R.anim.fade_out);
            dice.setAnimation(animation1);
        }
    });

this is the content of the fade_out animation:

<alpha
    android:duration="2000"
    android:fromAlpha="1"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toAlpha="0"
    />

and i´ve got this in the top part:

android:fillAfter="true"

this is my dice, its an array with 6 dice pictures in it:

private void changeDice() {

    Random random = new Random();
    int randomNumber = random.nextInt(6);
    dice.setBackgroundResource(dicee.getResourceId(randomNumber, 1));
}

im not sure how to connect all this to make the button appear and disappear each time. it works only once and since i put the dice image to "gone" added this:

dice.setVisibility(View.VISIBLE);
    dice.animate().alpha(1).setDuration(500);

i get some weird results, that i cant explain. first animation works, after that the dice appear, animation wont trigger again and on multiple clicks the dice sometimes disappear.

maybe someone might see what i could change to make it work.
