I have tried using styles and android:background:"#null" / android:background:"#color/transparent" inside AppBarLayout as well as inside V7 toolbar nothing seems to workout.
Have tried these solutions too :

On your AppBarLayout you need to set
android:background="#null"
or
android:background="#android:color/transparent"
im testing it right now and it's working for me
The thing is that if you have layouts inside your toolbar like here you probably need to set their backgrounds aswell
<LinearLayout
android:id="#+id/toolbar1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginRight="15dp"
android:gravity="center">
<ImageView
android:id="#+id/toolbar_title_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/signin"
android:visibility="gone" />
<ImageView
android:id="#+id/ivLogo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:visibility="gone" />
<TextView
android:id="#+id/toolbar_title_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:gravity="center"
android:textColor="#color/blue"
android:visibility="gone" />
</RelativeLayout>
</LinearLayout>

Try This
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/transparent"
android:theme="#style/AppTheme.AppBarOverlay"
app:elevation="0dp">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#android:color/transparent"
android:theme="#style/AppTheme.PopupOverlay"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:title="#string/app_name"
app:titleTextColor="#android:color/white" />
</android.support.design.widget.AppBarLayout>

Android making ViewPager scroll with parent activity layout

I have an android app in which I am trying to create the below layout -
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

app:elevation="5dp">

android:id="#+id/tat_tab_layout"
app:tabIndicatorColor="#color/white"
app:tabSelectedTextColor="#color/white"
app:tabBackground="#color/tab_primary_background"
android:layout_height="wrap_content" />
<android.support.v4.view.ViewPager
android:id="#+id/tat_viewpager"
android:layout_width="match_parent"

</LinearLayout>
</ScrollView>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
style="#style/Widget.Design.NavigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"

app:itemTextColor="#color/black_effective"
app:menu="#menu/drawer">
<TextView
android:id="#+id/tv_app_version"
style="#style/TextStyle.Title.Sub"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:padding="5dp" />
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
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.

I don't know this is a divider or elevation.please help me.
using styles? or what?

Try to add app:elevation="0dp" in your ToolBar.
Like this :-
<android.support.v7.widget.Toolbar
android:id="#+id/main_toolbar"
style="#style/MyDrawerArrowToggle"
app:elevation="0dp"
android:layout_width="#dimen/toolbar_height"
android:layout_height="#dimen/toolbar_height"
android:layout_alignParentRight="true">
</android.support.v7.widget.Toolbar>
Or you can use:-
<android.support.design.widget.AppBarLayout
android:id="#+id/appBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:elevation="0dp">
</android.support.design.widget.AppBarLayout>

Custom View not displaying completely in activity

I'm trying to display "Spaces-Navigation-View" from here https://github.com/armcha/Space-Navigation-View
The problem I'm facing is that the view appears perfectly in simple activity but not in my main activity which contains coordinator layout.
Here is the xml for my main activity and the result is below

I would like to make OpSearchView sticky to the top of the layout.
I try to remove app:layout_scrollFlags="scroll" from OpSearchView but all childs from AppBarLayout became sticky.
If I move OpSearchView from the AppBarLayout under RecyclerView, the RecyclerView(with layout_behavior) became invisible.
How to make OpSearchView without scrolling behavior?

This is the layout that I came up with working with your layout, I took a few liberties to make things work, you should make your own changes to get it back to your original layout, like your custom SearchView and HorizontalRecyclerView.
P.S. For layout_width and layout_height, match_parent and fill_parent are the same thing, and you should only use match_parent as per Google's documentation suggests.
