错误:错误: fragment 应该是静态的，这样它们才能被系统重新实例化，而匿名类不是静态的[ValidFragment]

private boolean checkFreeSpace(String path, long size) {
    long freeSpace = StorageUtil.getAvailableSpaceInBytes(path);
    if (freeSpace <= size) {

问题来了>>> new DialogFragment() {

如文档所述(Fragment Documentation):

Every fragment must have an empty constructor, so it can be instantiated when restoring its activity's state. It is strongly recommended that subclasses do not have other constructors with parameters, since these constructors will not be called when the fragment is re-instantiated; instead, arguments can be supplied by the caller with setArguments(Bundle) and later retrieved by the Fragment with getArguments().

所以我猜你正在扩展/实现一个 fragment 类并用参数重载一个构造函数。

您可以使用上面解释的 setArguments(Bundle) 方法修复它。
