Custom layout in Toolbar with TabLayout below

Right now, I have a normal looking Toolbar. What I want to do is add a custom layout between the Toolbar and the TabLayout, as shown in the picture below:
On the left is what my Toolbar looks like now, and on the right is what I want it to look like.
As you can see, I want to add an ImageView and two TextViews to the layout.
How can I achieve this?
Here is my current layout:
<?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:id="#+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/AppTheme.PopupOverlay" />
<android.support.design.widget.TabLayout
android:id="#+id/tablayout"
android:layout_width="match_parent"
android:layout_height="48dp"
app:layout_scrollFlags="scroll|enterAlways" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>

AppBarLayout extends LinearLayout, so you can add any number of views to your AppBarLayout: there's no reason to add the views specifically to your Toolbar.
You'll want to make sure you use the same layout_scrollFlags as your Toolbar if you want them to scroll the same.

Toolbar is just a ViewGroup, you can customize is as much as you want.
Try this :
<android.support.v7.widget.Toolbar
style="#style/ToolBarStyle"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="#dimen/abc_action_bar_default_height_material">
<ImageView
android:layout_width="wrap_content"
android:contentDescription="#string/logo"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="#drawable/ic_launcher"/>
This should bring your imageView in center of toolbar.

Glide + CollapsingToolbarLayout strange behavior

I'm facing a strange behavior when using CollapsingToolbarLayout, Toolbar and an ImageView embedded.
Here is my code :
<android.support.design.widget.AppBarLayout
android:id="#+id/bla"
android:layout_width="match_parent"
android:layout_height="256dp">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/md_white_1000"
android:minHeight="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Dark"
app:theme="#style/ThemeOverlay.AppCompat.Light" />
<ImageView
android:id="#+id/fragment_kids_profile_pic"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
And the Glide builder:
Glide.with(getActivity())
.load(file)
.fitCenter()
.into(profilePicture);
Before setting the image via Glide, the Toolbar behavior works exact as it should, in my case "pinned". After setting the image, the Toolbar layout goes missing and the image takes place (after scrolling up).
Some pics to clarify:
Before setting the picture:
Any help would be appreciated !

That happens because CollapsingToolbarLayout extends FrameLayout.
In FrameLayout the last view in the view hierarchy is the one on the top (if you haven't changed it in code), so it's normal that your ImageView covers the Toolbar. To solve this "issue" you have just to change the order:
<android.support.design.widget.AppBarLayout
android:id="#+id/bla"
android:layout_height="256dp"
android:layout_width="match_parent">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/fragment_kids_profile_pic"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:scaleType="centerCrop" />
<android.support.v7.widget.Toolbar
android:background="#color/md_white_1000"
android:id="#+id/toolbar"
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Dark"
app:theme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
Before you set the image via Glide the ImageView's background was transparent, this is why you could see the Toolbar.

Rotation issue with CoordinatorLayout and DrawerLayout

I have set up a DrawerLayout and a CoordinatorLayout in order to use a modern layout with a NavigationView and collapsing toolbar.
It works just fine until the device is rotated. Then the main_content is moved to a new permanent location. If I remove the appbar_scrolling_view_behavior from the main_content FrameLayout rotation works, but the content is no longer aware of the Toolbar.
Any advice?
activity_main.xml
<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_width="match_parent"
android:layout_height="match_parent"
android:background="#00ff00">
<!-- ACTIONBAR START -->
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"

<!-- MAIN CONTENT END -->
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView ...>
<!-- NavigationView code omitted ... -->
</android.support.v4.widget.DrawerLayout>
fragment_main.xml (loaded into main_content)
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".fragments.MainFragment">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Hello World!"/>
</FrameLayout>

A few points that should collectively resolve your problem:
The height of the AppBarLayout determins the expanded size of the collapsing toolbar, whilst the Toolbar determins the collapsed size. As such, you should set the AppBarLayout height to something more than the Toolbar (i.e. 280dp) to see the collapsing behaviour.
Immediately inside the AppBarLayout should be a CollapsingToolbarLayout, which contains the Toolbar and, optionally, other views too (normally an ImageView with a parallax collapse mode)
For the toolbar to collapse and expand correctly, it relies on a ViewGroup that supports nested scrolling (RecyclerView or NestedScrollView. As such, in your example you should try either changing main_content from a FrameLayout to a NestedScrollView, or conversely change the FrameLayout that forms the root layout of Fragment into a NestedScrollView.
Here is an example:
<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"
android:layout_width="match_parent"
android:id="#+id/coordinator_layout">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="240dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" >
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/collapsing_toolbar_layout"
app:contentScrim="#color/primary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/header_image"
android:src="#drawable/header_image"
android:scaleType="centerCrop"
android:contentDescription="#string/header_image"
app:layout_collapseMode="parallax"/>
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:id="#+id/toolbar"
app:layout_collapseMode="pin"
app:theme="#style/ThemeOverlay.AppCompat.Dark"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>

Design Support Library, Toolbar buttons cropped ripple

I'm trying to utilize the CoordinatorLayout, AppBarLayout, CollapsingToolbarLayout, Toolbar and a parallax'ed ImageView. It looks like the ripple effect of the toolbar menu items is cropped. The following image displays the ripple effect of the back button in expanded and in partially collapsed mode. In complete collapsed mode the ripple effect is not shown at all. I think this is caused by the parallax'ed ImageView that is positioned there.
Layout:
<?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_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.view.ViewPager
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
</android.support.v4.view.ViewPager>
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="224dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:weightSum="1.0">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="56dp"
android:layout_weight="1.0"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="48dp"
android:scaleType="centerInside"
app:layout_collapseMode="parallax"
app:layout_collapseParallaxMultiplier="0.4"/>
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="#color/transparent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:tabGravity="fill"
app:tabMode="fixed"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
The ImageView displays a 9-patch'ed Image. Is there something wrong with the layout or is it a bug/inability in the design support library to draw the ripple ontop of the ImageView?

I think your solution is here.
You can try to add this line:
<item name="actionBarItemBackground">?attr/selectableItemBackground</item>
in the theme/style of your Toolbar.
If it doesn't work, add this in your Toolbar attributes:
android:background="#android:color/transparent"

Overlaying content AppBarLayout using new Material Design

i want to achieve something like that. (not the FAB or the Snackbar). How can i create a layout, overlaying the AppBarLayout? Like this! V
Like the Play Store! V
My AppBarLayout with CoordinatorLayout and NestedScrollView with RelativeLayout as content looks like this! V

It would be awesome if someone could help me out. I can not find ANYthing on the internet..
Thank you in advance!

not difficult, some pseudo XML for you
<FrameLayout>
// this is the background part
<LinearLayout>
<Top part "blue">
<Bottom part "white">
<LinearLayout/>
// here is your main content that overlay the background
<MainContent margingTop="toolbar_height + something more"/>
// here is the toolbar with no background
<ToolBar background=#null height="toolbar_height"/>
<FrameLayout/>
