java.lang.IndexOutOfBoundsException:索引：0，大小：0？

所以，我正在创建一个网格视图

此活动的目的是通过使用网格视图进入将要显示的目录，该网格视图将从我的照片中显示我的照片。它应该能够正确显示我从网格视图中选择的图像

但是，当我进入活动时，它会崩溃并重新启动应用程序

java.lang.IndexOutOfBoundsException:索引：0，大小：0

您正在使用：

setImage(imgURLs.get(0), galleryImage, mAppend);

这意味着

imgURLs

有0个元素。
在使用

imgURLs.get（0）

之前，只需检查它是否有第一个元素，例如：

if (imgURLs != null && imgURLs.size()>=1) { ... }
