Creating a separate view for FastScrollBar and moving all the relavant logic in the view. For protrait, the touch handling is delegated by the recycler view just like before. For landscape, the dcrollbar does not overlay with recyclerView and handles the touch itself Bug: 37015359 Change-Id: Ie1981326457ba739bdf0ac8063db1065f395f133
