Swipe/drag Android view from the bottom of the screen

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?
