Custom header layout with AppBarLayout and Toolbar

How to develop my custom header with Toolbar and AppBarLayout ?I want to add my own custom xml using this.
<android.support.design.widget.AppBarLayout
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="?android:attr/actionBarSize"
android:supportsRtl="false"
app:popupTheme="#style/AppTheme.PopupOverlay">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>

try something like this:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:id="#+id/toolbar"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/AppTheme">
<android.support.constraint.ConstraintLayout
android:id="#+id/ConstraintContainer"
android:layout_width="match_parent"
android:orientation="vertical"
android:background="#android:color/black"
android:gravity="center"
android:layout_height="wrap_content">
<!--Whatever textview/imageview you want to insert-->
</android.support.constraint.ConstraintLayout>
</android.support.v7.widget.Toolbar>

NestedScrollView not showing last cardView with CoordinatorLayout & CollapsingToolbarLayout

I set up a CoordinatorLayout with a AppBarLayout and a CollapsingToolbarLayout, everything works fine, in this part. Under the AppBarLayout I put a NestedScrollView but when I scroll to the end I can see only half of the last cardview.

In my activity :
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
What is wrong with my layout ? I looked at some examples but everything look good to me.

you need to get rid of nestedscrollview layout gravity. It worked for me.

This is the output i got
toolbar appears only in prelollipop device but not working in lollipop.

Toolbar needs the collapse_mode flag.
app:layout_collapseMode="pin"
Pin will say that the toolbar has to be pinned at the top

CollapsingToolbarLayout with tablayout & image as collapsing with sticky toolbar
