In my android app I need to create a view that user can slide up and down with finger. Not just slide up/down with swipe/fling but slide up/down when finger is held down on screen.
Like Snapchat Memories slide view.
I have tried using BottomSheetDialog but problem is, I need to keep a peekHeight in order to swipe as I require it. If I use BottomSheetDialogFragment and set peekHeight to 0 then I need to use show() on FragmentManager which just leaves me with two options; to set peekHeight or expand completely.
There is a utility class called ViewDragHelper. I saw some examples but again, all examples showed the view partially visible in order to drag it up/down.
Is there any way, I could use BottomSheetDialog or BottomSheetDialogFragment and create user swipe like snapchat memories.
If ViewDragHelper can be used could someone provide me with an example where view is completely hidden at beginning? The reference docs are quite confusing.
