You should add app:layout_scrollFlags="scroll|enterAlways" in child(in your case <android.support.v7.widget.Toolbar>) of <android.support.design.widget.AppBarLayout> to achieve on scroll down hide app bar and on scroll top show app bar.

Use below format code this will work for you what you want.

How to put a custom view/layout pinned in CollapsingToolbarLayout ?

Background
The support/design library allows to have a nice resize-as-you-scroll effect, using AppBarLayout and CollapsingToolbarLayout :
http://material-design.storage.googleapis.com/publish/material_v_3/material_ext_publish/0B0NGgBg38lWWcFhaV1hiSlB4aFU/patterns-scrollingtech-scrolling-070801_Flexible_Space_xhdpi_003.webm
The problem
All examples I've seen are of Toolbar being the one pinned as you scroll.
What I'm trying to achieve is that a custom view will be pinned, in a size of a toolbar, while the content above it (some other views) will shrink as you scroll.
Something like that:
Thing is, no matter what I try, something doesn't work this way. Sometimes the content of the toolbar-replacement gets truncated, sometimes it doesn't get pinned, etc...
What I've tried
Since for some reason the Toolbar is the only thing that seems to work well with the app:layout_collapseMode="pin" attribute, I tried to either put views in it, or put views with it.
Here's the current XML layout of what I've tried:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

android:theme="#style/AppTheme.AppBarOverlay">
<android.support.design.widget.CollapsingToolbarLayout

android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"

app:contentScrim="#eeeeee"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:title="">
</android.support.v7.widget.Toolbar>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="bottom"
android:layout_marginBottom="0px"
android:background="#33ff0000"
android:gravity="center"
android:orientation="horizontal">
<TextView
android:id="#+id/titleTextView"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom"
android:background="#33ffff00"
android:gravity="center"
android:text="someText"
android:textColor="#000"/>
</LinearLayout>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_scrolling"/>
</android.support.design.widget.CoordinatorLayout>
Sadly, even though the layout editor shows that it looks ok, what I actually see is this truncated text for the toolbar-replacement view:
I also tried using layout_anchor, as shown on a sample of how to use it (here), but even then, the view that is supposed to replace the toolbar seems to overlap the content that's supposed to be below it and the one above it, and even the view that's above it have some space below it that isn't supposed to be there:
And here's the XML layout of this try:

The questions
How can I put custom views so that the toolbar content will stay between the bottom and upper areas, not overlapping any of them, and have the area above the toolbar to shrink as you scroll ?

For now, I'm using a workaround for this issue, by using padding that will prevent the overlapping of the views. I still don't get why the views overlap, but this helps against it.
The problem with this, is that now the toolbar doesn't have a shadow when I scroll enough so that it's the only thing that appears at the top.
Here's a sample XML layout, in case anyone wants to try:

Scroll problems - CoordinatorLayout + AppBarLayout + ViewPager with Fragments containing RecyclerViews

I have the following layout:
<CoordinatorLayout layout_height="match_parent">
<AppBarLayout layout_height="match_parent">
<CollapsingToolbarLayout layout_height="match_parent">
<ImageView> //Fullscreen picture
<LinearLayout> //Some text and icons
<Toolbar layout_height="?attr/actionBarSize"> //No title
<TabLayout layout_height="?attr/actionBarSize"> //Drawn on top of the invisible Toolbar
</CollapsingToolbarLayout>
</AppBarLayout>
<ViewPager layout_height="wrap_content"/>
<FloatingActionButton/>
</CoordinatorLayout>
Now, the ViewPager has 3 fragments, each with a RecyclerView inside it. I believe this should be a regular design pattern. The ViewPager sits below the AppBarLayout, which starts full screen, so you have to scroll down to see the ViewPager content.
The problem is when I fling on the AppBarLayout, the fling event prevents any further scroll until it stops flinging (until velocityY = 0). But this takes up to 2 or 3 seconds sometimes, so in the meanwhile, the touchpad remains unresponsive.
What is worse, if I try to scroll on one of the children RecyclerViews, the screen will flicker so badly and the RecyclerView will suddenly appear at the scrolled position once the AppBarLayout fling has ended. This is horrible!
I've already tested this smooth AppBarLayout library and while it fixes some issues, it introduces some other bad ones (the ViewPager is drawn on top of everything, and not below the TabLayout).

FrameLayout doesn't fill CoordinatorLayout after GONE a view

Here is my main layout :

android:layout_height="match_parent"
android:background="#color/green"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
After event onClick on TextView (id/close), I set visibility for RelativeLayout (id/top_con) to GONE. But FrameLayout (contain a recycler view) still keep their height, and there's a white space (white is background color of CoordinatorLayout ) at bottom of sreen.
What is problem and how can fix it?
Thank you!
