Java android roulet：当roullet旋转和roullet自动调整大小时，内部开始图像禁用

我开发了一个应用程序，因为我有轮盘赌，轮盘赌旋转得很好，但是

问题1：轮盘赌有开始的内部图像，当我单击开始时，轮盘赌旋转：当轮盘赌旋转时，我希望我的开始图像消失，当轮盘赌停止时，我希望它再次可见

问题2：我有一张固定大小的轮盘赌图像，但当轮盘赌旋转时，它会自动调整大小，我不想这样，我不知道轮盘赌为什么会自动调整大小。我想解决这个问题

我的代码如下：

代码如下所示

这很简单，只需在动画末尾添加一个侦听器

private OnClickListener onClick = new OnClickListener(){
   @Override
   public void onClick(View v){
       v.setOnClickListener = null;
       wheel.animate().addListener(animatorListener)... the rest of your animation
   }
};

然后在动画结束时，删除侦听器并重新添加单击侦听器

private AnimatorListenerAdapter animatorListener = new AnimatorListenerAdapter(){
   @Override
   public void onAnimationEnd (Animator animation){
         animation.removeListener(this);
         button.setOnClickListener(onClick);
   }
}

你能粘贴一些代码吗？
