Swipe/drag Android view from the bottom of the scr

Question

I want to do in my app a View that I can swipe from the bottom of the window (Images below explain it better).

I want the view to stop at certain point. The view must allow to swipe/drag it to the bottom again. Any idea or tip of how can I do that?

Answer 1

You can use the new material design pattern called Bottom Sheets. They do the exact thing that you want. They also support custom layouts for the view.
