因此，我创建了动画列表并设置了按钮，但是当我单击调用动画方法的按钮时，应用程序关闭并显示“不幸的是，测试已停止工作”。

我相信问题出在动画方法上，但不知道它是什么，并尝试了几种不同的方法来解决它。

private void homeAnimate() {
    ImageView homeScreenImage = (ImageView) findViewById(R.id.imageView1);
    homeScreenImage.setImageResource(R.drawable.home_animation);
    AnimationDrawable homeAnimation = (AnimationDrawable) homeScreenImage.getDrawable();
    if(homeAnimation.isRunning()){
        homeAnimation.stop();
    }
    homeAnimation.start();
}

任何人都可以看到这种方法的问题吗？

如果它真的很简单，我也很抱歉，我没有做过太多的 Android 编程。虽然我之前做过动画，但效果很好。

谢谢
