Answer 1

In this pretty similar issue: collapsing toolbar layout like google play store, you would find an answer as below:

View inside CollapsingToolbarLayout no need to set app:layout_scrollFlags. No effect. Base on my code, change app:layout_scrollFlags in CollapsingToolbarLayout to app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed" and set minHeight for it.

As your toolbar is "pin", so enterAlwaysCollapsed will call it when you scroll down.

In the comment to that post, you would find also a hint:

add app:contentScrim="?attr/colorPrimary" to your collapsingtoolbarlayout. It is no need two toolbars to implement this effect

EDIT: Here you would find an interview with a guy responsible for Google Play Store, he's talking about how he build design in Play Store App:
