Answer 1

After reading your descriptions about your question, I thought styles of Google Photos matches your requirement.

OK, there are just some tips for your question. After my test, it works.

• If you want to show content behind status bar, you need add true into your style when Android version level is larger than 19(namely KitKat)
• If you want to show content behind navigation bar, you need add true into your style when Android version level is larger than 19(namely KitKat)
• If you want to hide Toolbar smoothly when content is scrolled up and to show Toolbar smoothly when content is scrolled down, you need to add app:layout_collapseMode="parallax" into your Toolbar's attributes based on your current codes.Of course, you need coordinate Toolbar with CollapsingToolbarLayout CoordinatorLayout and AppBarLayout.
