How does PocketCasts perform this transition / effect?

Material updates PocketCasts has amazing transition animations for onClick list items. Is this done by adding a view / fragment to the existing coordinator scheme for this activity? Any ideas on how I can implement this?

LEFT: Shown upon clickin a list item. "Pops up" from bottom. RIGHT: Scrolling the "pop up" brings it to cover the whole screen

All user codes based on raw touch events, with OnTouchListener, GestureDetector (onScroll, onFling, etc.) and OverScroller, to help calculate the speed, should be moved.

The view itself is just a class that extends FrameLayout, which we move up and down in the code.

Flipboard has opened the original version of its bottom.

Maybe you should check this out before trying to write your own version, @rustyshelf is a genius, and it's almost impossible.;)
