nested scrolling counts in GONE and INVISIBLE view which is not correct

[Jenna233]

In canViewScrollUp and canViewScrollHorizontally check every view of parent , including the invisible ones which is wrong. In my project, some views are invisible, they should not be considered in nested scrolling.

I think it's better for CustomSwipeLayout to implement NestedScrollingParent and NestedScrollingChild to support nested scrolling, this is the way the android system supports.
