Android making ViewPager scroll with parent activity layout

I have an android app in which I am trying to create the below layout -

So, in this layout as you can see I want to add a TabLayout and a ViewPager below some views. Now the problem I am facing is my ViewPager is restricted to the available space at the bottom of the screen so, only the viewpager is scrollable and not the full activity layout. Which leaves very little space at the bottom to see the viewpager contents.
So, I want to make the whole layout below the appbar scrollable from the top so that the fragments inside viewpager are easily and conveniently visible.
------------Update---------
I tried using the Nested Scroll View, setFillViewPort, and the collapsing layout as suggested but still getting the same result.
Updated layout xml with Collapsing ToolbarLayout -

The nested scroll views I copied from - https://github.com/TheLittleNaruto/SupportDesignExample/tree/master/app/src/main/java/com/thelittlenaruto/supportdesignexample/customview
Now, the viewpager is scrolling but my actionbar title is not visible anymore.
Can someone suggest any changes to this layout that could fix this issue ?

I have tried to refine your code and if I am not wrong you wanted it to be scrollable,you can try the following code.

I have made minor changes.
Try not to use weights when using scrollView.As they don't work so
well with each other.
I have wrapped Tab layouts in a Linear Layout
and gave it static height(can be replaced easily).
Hope it helps.

Custom Toolbar design

I'm building a custom toolbar for search activity and it's suitable in some devices and not suitable in other screens .
i tried it on my device 720*1280 and it's fine . but when i open app on genymotion device 768*1280 it appears like that .
search_toolbar.xml
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

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

Search.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_width="match_parent"

You should modify you Search.xml like this (Remember add app:layout_behavior="#string/appbar_scrolling_view_behavior" in your recyclerview):
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/search_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#drawable/search_bar_bg"
app:popupTheme="#style/AppTheme.PopupOverlay">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<ImageButton
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_marginBottom="2dp"
android:layout_weight=".1"
android:background="#fff"
android:clickable="true"
android:onClick="back"
android:src="#drawable/ic_arrow_back_black" />
<EditText
android:id="#+id/searchText"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_gravity="center_vertical"
android:layout_marginLeft="5dp"
android:layout_weight=".99"
android:hint="#string/search"
android:padding="3dp"
android:textColor="#000"
android:textColorHint="#FFCEC9C9"
android:textSize="15sp"
android:textStyle="bold" />
</LinearLayout>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/search_recycler"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="8dp"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>

Try android:theme="#style/ThemeOverlay.AppCompat.ActionBar" in AppBarLayout.

Coordinator Layout cuts off screen from bottom

Here I'm hiding and showing TabLayout using CollapsingToolbarLayout inside CoordinatorLayout but it everytime cuts mobile device screen and shows of black color at bottom as

Nested Scrollview + Recycler View

I have a layout which has a collapsable image view, along with the GridView in the layout, and many more things in the UI . But the screen is scrolling upto the image scroll, that is it scrolls up only till the header image is not visible. After that it neither scrolls.
How can I solve that ?
Here are my layouts:

for doing that remove the line android:fitsSystemWindows="true" from everywhere in code(you used 3 times).

How to put RelativeLayout inside CoordinatorLayout

I'm trying to recreate the search box as it is in Airbnb Android app.
So I'm using CoorinatorLayout with Toolbar and RecyclerView.
But when I insert something inside the Coordinator besides those two things, it doesn't show up.
Here is my code:
<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/slidingLayout"
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.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/red"
app:layout_scrollFlags="scroll|enterAlways" />
</android.support.design.widget.AppBarLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="50dp"
android:layout_marginRight="50dp"
android:layout_marginTop="20dp"
android:background="#drawable/rounded_background"
android:orientation="horizontal"
android:padding="6dp"
app:layout_scrollFlags="scroll|enterAlways">
<EditText
android:id="#+id/search"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="6"
android:background="#null"
android:fontFamily="sans-serif-light"
android:hint="Unesite grad"
android:paddingLeft="16dp"
android:paddingStart="16dp" />
<ImageView
android:id="#+id/cancelSearch"
android:layout_width="0dp"
android:layout_height="40dp"
android:layout_weight="1"
android:padding="10dp"
android:src="#drawable/ic_cancel" />
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_below="#id/appbar"
android:background="#ffffff"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
But actually if this even worked, I would have the trouble of putting the search box above the RecyclerView.
I have tried to put everything inside the RelativeLayout but that didn't work.
Here is also the picture of what I'm trying to make
EDIT:
Here is the code with RelativeLayout
<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/slidingLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
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/ThemeOverlay.AppCompat.Dark.ActionBar"
android:background="#00000000">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/red"
app:layout_scrollFlags="scroll|enterAlways"/>
</android.support.design.widget.AppBarLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="50dp"
android:layout_marginRight="50dp"
android:layout_marginTop="20dp"
android:background="#drawable/rounded_background"
android:orientation="horizontal"
android:padding="6dp"
app:layout_scrollFlags="scroll|enterAlways">
<EditText
android:id="#+id/search"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="6"
android:background="#null"
android:fontFamily="sans-serif-light"
android:hint="Unesite grad"
android:paddingLeft="16dp"
android:paddingStart="16dp" />
<ImageView
android:id="#+id/cancelSearch"
android:layout_width="0dp"
android:layout_height="40dp"
android:layout_weight="1"
android:padding="10dp"
android:src="#drawable/ic_cancel" />
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_below="#id/appbar"
android:background="#ffffff"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</RelativeLayout>

I was trying to do something a little similar, but with an ad banner at the bottom of the screen. My solution was to wrap the RelativeLayout outside the CoordinatorLayout as so:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/ad_view">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/my_list_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
<com.google.android.gms.ads.AdView
android:id="#+id/ad_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:layout_gravity="center|bottom"
app:adSize="SMART_BANNER"
app:adUnitId="#string/admob_id" />
</RelativeLayout>
The toolbar properly hides when scrolling inside the RecyclerView and everything seems to be working just fine. I would imagine if you followed a similar principle you should be good-to-go.

If you want remove status bar white colour, you must remove the next line
<item name="android:statusBarColor">#android:color/transparent</item>`
in v21/styles.xml
Thanks for example.

<LinearLayout

android:layout_marginTop="20dp"
android:background="#drawable/rounded_background"
android:orientation="horizontal"
android:padding="6dp"
app:layout_scrollFlags="scroll|enterAlways">
<EditText
android:id="#+id/search"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="6"
android:background="#null"
android:fontFamily="sans-serif-light"
android:hint="Unesite grad"
android:paddingLeft="16dp"
android:paddingStart="16dp"/>
<ImageView
android:id="#+id/cancelSearch"
android:layout_width="0dp"
android:layout_height="40dp"
android:layout_weight="1"
android:padding="10dp"
android:src="#drawable/ic_cancel" />
</LinearLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_below="#id/appbar"
android:background="#ffffff"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
Check if this works for you.
