Android drawBitmap能否将ArrayIndex抛出BoundsException？

我的代码的错误部分：

        System.out.println(frame + ", " + ((frame / 10) % 2) + ", " + dyingBoxRelated[1] + ", "
                + (bad[dyingBoxRelated[1]][0] - radBad) + ", "
                + (bad[dyingBoxRelated[1]][1] - radBad) + ", " + radBad + ", "
                + littleBad[(frame / 10) % 2]);
        try {
            canvas.drawBitmap(littleBad[(frame / 10) % 2], bad[dyingBoxRelated[1]][0] - radBad,
                    bad[dyingBoxRelated[1]][1] - radBad, null);
        } catch (Exception e) {
            System.out.println(e);
        }

我真的不明白这里发生了什么。 我在try-catch上面添加了一个System.out来监视变量的所有值，这就是我得到的：

一切都很顺利，直到某个时候我开始得到ArrayIndexOutOfBoundsException错误。。。 发生什么事？为什么应用程序在尝试显示值时没有在System.out崩溃？ 那里唯一长度为2的变量是littleBad[]。。。

---

它是drawBitmap方法的内部内容吗？

最重要的是，它是用于数组的无效索引

littleBad

或

bad

或

dyingBoxRelated

。将赋值提取到单独的变量中，您将了解更多。也不是做

System.out.println（e）

do

Log.e（TAG，e）

no，put访问数组可以。没有无效的。。。我正在显示变量的所有值。。。
