How do I correctly implement toolbars inside fragments in viewpager?

I have a collapsing toolbar in my TimelineFragment which I recently added. And there is an already existing collapsing toolbar which previously worked fine in my ProfileFragment until when I added the similar toolbar to the TimelineFragment. Both of these fragments are contained in a view pager.
I have the ff layout for the ProfileFragment

For visuals on what my issue is
** This image is from the ProfileFragment
The extra space which I marked red has not existed before, when I still haven't added the AppBarLayout (containing the toolbar) on the TimelineFragment.
I have tried removing the whole AppBarLayout on the TimelineFragment, and it does fix the weird extra space on the ProfileFragment. Why is it that there is a relation between these fragments when they do not share anything besides being in the same ViewPager?
How do I remove the space that I marked red on the image? It might be related to the toolbar since it is same in color. The AppBarLayout uses a lighter color than the toolbar.

I have already fixed it. Apparently, the Activity that was holding all these fragments is using coordinator layout. So I removed that, and that space was gone. I believe that using a toolbar inside these fragments made the activity holding them create a toolbar on its own.

CollapsingToolbarLayout pushes toolbar text outside the screen.

Hi I'm trying to use Collapsing Toolbar but when the collapsing toolbar collapses the title of the toolbar moves outside the screen. I'm using right alignment for the text as i'm trying to build an app in Urdu language. I have searched on this and not no solution. Need help!

Thanks in Advance :)

I could not find a better answer or solution to this problem. Now i have added a TextView at the right of the toolbar title. Which basically consume some space so the title comes at the required place. And i know its not the best practice. If someone has a better solution Please share.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/toolbar"
app:title="#string/Quran"
android:gravity="right"
app:popupTheme="#style/ThemeOverlay.AppCompat.Dark"
app:layout_collapseMode="pin" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="10dp"
android:layout_gravity="right" />
</android.support.v7.widget.Toolbar>

in your CollapsingToolbarLayout try to add this app:layout_scrollFlags="scroll|exitUntilCollapsed"
like this
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="350dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleTextAppearance="#android:color/transparent"
android:fitsSystemWindows="true"
app:layout_scrollFlags="scroll|exitUntilCollapsed">

So inside the collapsing toolbar layout i have a toolbar and its stuck at the top.There should be a toolbar below which there is a view pager .
I am not able to figure out why. If its a silly mistake forgive me. I am new to android.

I am replacing the frame layout with fragment. The toolbar in my activity is getting replaced by the fragment toolbar once the fragment is back pressed. I hope this helps explain my problem more clearly.

android:fitsSystemWindows="true" add this line in your root view.

Put you toolbar inside "NestedScrollView"

Maybe this will help? https://github.com/ksoichiro/Android-ObservableScrollView
You can just observe the scrolled area and show/hide the toolbar when necessary.

Use this code for Toolbar:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"/>
Explanation :
The scroll flag used within the attribute app:layout_scrollFlags must be enabled for any scroll effects to take into effect.
For more information and different scrolling effects check Handling-Scrolls-with-CoordinatorLayout

If you want to achieve that without using any libraries, you have to put Toolbar inside the CollapsingToolbarLayout. Here is the working layout.

When I re-expanding layout, top part (toolbar, tab etc) is not working in ICS and jelly bean. I have tested, It was working above all versions. I think top part height is fixed after collapsing (it takes toolbar's height) in lower OS. Let me suggest any solution.
Thanks in advance.
