自定义后造成 java.lang.NullPointerException: Attempt to invoke virtual method 'int com.luck.picture.lib.entity.LocalMediaFolder.getFolderTotalNum()

[10433yx]

Will this problem occur in demo?

Demo能否复现这问题？

能
您好，我这个是以fragment形式把图片选择页放在viewpager中的其中一个fragment，然后头部是全自己写的，有图片选择、草稿箱、本地，一点击图片item预览，再返回图片选择页就是报这个错误，请问这个异常可以在哪里加个setCurrentLocalMediaFolder好避免这个问题吗？我不知道加在哪里比较好，非常感谢，我有点无从下手
