android - java.lang.ArrayIndexOutOfBoundsException while switch portrait and landscape (交错 GridView 库)

Question

我解析图像 url 论坛 json 数组并将它们添加到 staggeredgridview 所以布局看起来像 pinterest :)

为了将 Orientation landspace 切换为 portrait 或 portrait to landspace ı 创建两个布局文件，其中一个是 layout-port(它有 2 列)另一个是 layout-land(它有 3 列)。

当我尝试切换陆地到港口时，它是正确的，但港口到陆地返回 ArrayIndexOutOfBoundsException

错误

Answer 1

看起来像是 StaggeredGridView 中的错误onSaveInstanceState() 和 onRestoreInstanceState()。它假定列数保持不变，而布局和纵向资源的列数不同。

对你来说很好，它是开源的，你可以修复它:)

作为一种快速解决方法，您可以使两个方向的列数保持相同，或者尝试在 SGV 上调用 setSaveEnabled(false)，这样 onSaveInstanceState() 就不会接到电话。
