How to show/hide fragment with swipe up/down like soundcloud android app

Question

I am getting curious to know that how a view can be created like the one shown below . Is this drag and drop or some custom view with gesture detection and animations? What can be a good starting point?

Answer 1

ViewDragHelper can be used to achieve this effect. Some good tutorials and samples are: dragging-with-viewdraghelper and each-navigation-drawer-hides-a-viewdraghelper and DraggablePanel and AndroidSlidingUpPanel

Answer 2

Checkout BottomSheetDialogFragment from new Material design, here is a good tutorial on how to do it
