目标：能够点击按钮，使图片发生变化并保持在该图像上。问题是我不能更改 imagebutton9 上的图片。当我点击 imagebutton9 时，它会更改 imagebutton1 上的图片。所以问题是有人知道是什么导致了这种情况的发生吗？

改变：

} else if (changer == 0 && antiChange9 == 0) {
    imageView1 = (ImageView) findViewById(R.id.imageButton1);
    imageView1.setImageResource(R.drawable.x1);
    tellerbytter();
    antiChange9++;
    break;
}

至：

} else if (changer == 0 && antiChange9 == 0) {
    imageView1 = (ImageView) findViewById(R.id.imageButton9);
    imageView1.setImageResource(R.drawable.x1);
    tellerbytter();
    antiChange9++;
    break;
}

在您case对第九个图像按钮的声明中。

此外，您的所有 etcif (v.getId() == R.id.imageButton1) {语句都不是必需的，因为您已经将它们放在执行相同操作的 switch-case 中。
