Android collapsing Action bar with swipeable tabs

I'm trying to achieve a page as shown in the link. Can anyone please help me how to get it.

https://github.com/kaedea/Andriod-Seamless-ViewPager-Header
I Referred This example its working fine for me.please try this one surely u ll got.

Try this library ,Seamless viewpager
https://github.com/kaedea/Andriod-Seamless-ViewPager-Header

For expanding and collapsing toolbars (doesn't matter if it has tabs or not):
<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:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.CoordinatorLayout>

Try this XML: and in view pager you can get swipes as per tab of tablayout selection.

Testing it on my device i get this
The ViewPager Fragment overlays the TabLayout if it has content and displays the TabLayout on top of the ImageView when there is no content.
What am i doing wrong, i am still somewhat of an Android noob.

CollapsingToolbarLayout needs a minHeight. This tells the parent AppBarLayout how much it can collapse. I assume you want the Toolbar and the TabLayout to stay at the top of the screen (because you are using the exitUntilCollapsed scroll flag). I would make both of those have android:layout_height="?attr/actionBarSize" and use double that value as the minHeight of the CollapsingToolbarLayout.
ViewPager needs app:layout_behavior="#string/appbar_scrolling_view_behavior".
