I've been looking everywhere for this w/ no luck. The Android Support Design library seems to be designed for doing parallax only on an image, but I want a header that's more like a framelayout or linearlayout with a bunch of elements including an image w/ overlaid text and gradients on top of it. Ie, a more complicated header that shrinks w/ text that parallaxes into the status bar title w/ a different font size.
Does anyone know how to do this? I tried nesting a NestedScrollLayout but that's not what I want to do either :-(
You can use the CollapsingToolbarLayout
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="match_parent"
android:background="@android:color/white"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout

android:layout_width="match_parent"
android:layout_height="@dimen/detail_backdrop_height"

android:fitsSystemWindows="true">
