android - Carousel 中的 ArrayIndexOutOfBoundsException - MessageQueue 回调和 handleReceiveCallback 中的异常

Question

我在我的应用中使用轮播。

对于拥有 Android 4.2.2 且仅处于横向模式的用户，他们报告了此问题:

我找不到这里的问题。

Answer 1

看起来您正在将 Views 存储在一个数组中。

当设备旋转时，这个数组会被重置，所有的 View 都会被移除。当数组适配器试图获取其位置时，由于数组为空，它返回 -1。

尝试处理旋转事件并确保重新填充数组。

如果没有看到一些代码，我无法肯定地回答，但它确实看起来数组/ View 列表正在被清空或设置为 null。
