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

我在我的应用程序中使用轮播.

对于拥有Android 4.2.2且仅在横向模式下的用户,他们报告此问题：

我无法在这里找到问题所在.

解决方法

看起来您将视图存储在数组中.

旋转设备时,将重置此阵列并删除所有视图.当数组适配器尝试获取其位置时,因为该数组为空,所以它返回-1.

尝试处理旋转事件并确保重新填充数组.

我没有看到一些代码就无法回答,但它看起来像是清空或设置为null的视图数组/列表.
