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. I.e., 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

Bugged title
Hey, as you can see in this picture, I am trying to use the CollpasingToolbarLayout but the title is not being drawn correctly. In the expanded state I set the title to fade out like this:
val collapsingToolbarLayout = layout.findViewById<CollapsingToolbarLayout>(R.id.collapsing_toolbar)
collapsingToolbarLayout.setExpandedTitleColor(android.R.color.transparent)
so the expanded state isn't really important. My xml looks like this:
<android.support.design.widget.CoordinatorLayout

Whan can I try? I am thinking this is a bug but I wouldn't know. Thanks
android:fitsSystemWindows="true" typically adds the appropriate padding in some cases to make sure that views are not layered under the status bar/nav bar. In your case, I think that is the cause of pushing your text downwards.
You may need to play around with this, but try removing it for your AppBarLayout and its children and perhaps try some different combinations.
It may also help to show us the view boundaries so we can see where the views actually are. This can be done either in the Android Studio preview or via developer options
I have a linnear layout at the top of recyclerview. I used nestedscrollview to drag it from bottom. When linear lyout reaches the top scroll behaviour of recyclerview should activated. Top linear should act as toolbar. I want bottom sheet similar to google maps navigation screens bottomsheet.
Thanks in advance
Instead of that you can go with CollapsingToolbarLayout. This will fulfill your requirement.

I have issue and i don't how to solve it.
So, how to make ImageView in CollapsingToolbar overscrollable?
For example,
CoordinatorLayout
-- AppBarLayout
-- CollapsingToolbarLayout
----30% Non visible part----
----40% Visible part, center of image----
----30% Non visible part----
--NestedScrollView <-- Here content
How to make when user fling down by image, make image visible part of image bigger? I tried to wrap imageview into scrollview and make overscroll, but image is cropped.
Any ideas?

I'm seeing an issue with my app when using the Android design support library in that the CollapsingToolbarLayout appears to have a theme-coloured background bar at the top, even when there is enough space (and therefore it should be 'transparent').
Any ideas what I'm doing wrong?

I'm having very similar layout in my app and it's working well for me. Comparing mine layout to yours, my guess is you should remove background attribute from your Toolbar. Furthermore, I use one of the default themes for Toolbar (#style/ThemeOverlay.AppCompat.Dark). I see you're using your own theme, which might be causing problem as well. (I set StatusBar color to transparent in Java code, if you're interested in that too).
The behavior of CollapsibleToolbarLayout with regards to the RecyclerView seems broken. When setting a value for
app:layout_scrollFlags
If you do not use "scroll|enterAlways", the Collabsible layout will never expand. It will always contract, but when you pull down, it does not expand anymore, so it just gets locked to the top.
If you use "scroll|enterAlways", it works as expected, meaning it instantly expands the header to its full height whenever you scroll down.
Without knowing anymore, it seems as if the Collapsible layout cannot properly determine when the RecyclerView is at the top of the list, as that is the criteria for when it should expand to full height in the other cases.
Here is the layout that I am testing with. The java code isn't really important, it is just populating the recyclerview with dummy data and using a LinearLayoutManager.
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />

android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:toolbarId="#id/toolbar_id"
app:contentScrim="#color/white"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_id"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_collapseMode="pin"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
Try with scroll|enterAlways|enterAlwaysCollapsed. This way the toolbar should always enter in the collapsed mode, and then expand when you reach the top of the sibling view.
If you want to show a list with RecyclerView under the AppBarLayout you should place the RecyclerView XML under
