Android - Unable to fix the Toolbar in a Collapsing Toolbar layout

I am currently using CollapsingToolbar Layout in the upper portion of my layout. I want to collpase a particular portion (LinearLayout only) and keep the toolbar fixed on the top. I was able to fix the Toolbar position on top in another project and keep it from collapsing. However, for some reason, I am not able to fix the position of my toolbar. Any help will be appreciated. Here is my the XML of the layout:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/profile_coordinate_layout"
>

<android.support.design.widget.AppBarLayout
    android:id="@+id/app_bar_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >
    <android.support.design.widget.CollapsingToolbarLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_scrollFlags="scroll|enterAlways"
        android:layout_gravity="fill_vertical"
        android:fitsSystemWindows="true"
        app:layout_collapseMode="pin"
        app:expandedTitleMarginStart="?actionBarSize"
        app:contentScrim="?colorPrimary"
        >

        <!--|||||||||||||||||||||||||||||||||||||||||||||||||-->
        <!--|||||||||||||||Collection Profile and about||||||-->
        <!--|||||||||||||||||||||||||||||||||||||||||||||||||-->
        <LinearLayout
            android:id="@+id/ll_header"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginTop="?actionBarSize"
            android:orientation="vertical"
            app:layout_collapseMode="pin"
            android:background="@drawable/gradient_feed_bg"
            >
            <include
                layout="@layout/item_collection_profile" />
        </LinearLayout>


        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?actionBarSize"
            android:background="@drawable/dark_primary_no_radius"
            app:layout_collapseMode="pin"
            android:elevation="@dimen/margin_4dp"
            >
            <include layout="@layout/action_bar_collection_profile"/>
        </android.support.v7.widget.Toolbar>
    </android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>


<android.support.v4.view.ViewPager
    android:id="@+id/view_pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    ></android.support.v4.view.ViewPager>
</android.support.design.widget.CoordinatorLayout>

I am loading another fragment on the ViewPager. and I am using the following code to load the toolbar.

findViewById(R.id.toolbar). setBackgroundResource(R.drawable.dark_primary_no_radius);
setSupportActionBar((android.support.v7.widget.Toolbar)findViewById(R.id.toolbar));

And here is UPDATED the result:

enter image description here

As you can see, in the second image, toolbar collapsed on the top. Any help will be highly appreciated.

Thank you.

You need to use the app:layout_collapseMode="pin" in Toolbar only. Remove this from other components like the LinearLayout and CollapsingToolbarLayout.

<android.support.design.widget.AppBarLayout
android:id="@+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<android.support.design.widget.CollapsingToolbarLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
  app:layout_scrollFlags="scroll|exitUntilCollapsed"
    android:layout_gravity="fill_vertical"
    android:fitsSystemWindows="true"
    app:expandedTitleMarginStart="?actionBarSize"
    app:contentScrim="?colorPrimary"
    >

    <!--|||||||||||||||||||||||||||||||||||||||||||||||||-->
    <!--|||||||||||||||Collection Profile and about||||||-->
    <!--|||||||||||||||||||||||||||||||||||||||||||||||||-->
    <LinearLayout
        android:id="@+id/ll_header"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="?actionBarSize"
        android:orientation="vertical"
      app:layout_collapseMode="parallax"
        android:background="@drawable/gradient_feed_bg"
        >
        <include
            layout="@layout/item_collection_profile" />
    </LinearLayout>


    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?actionBarSize"
        android:background="@drawable/dark_primary_no_radius"
        app:layout_collapseMode="pin"
        android:elevation="@dimen/margin_4dp"
        >
        <include layout="@layout/action_bar_collection_profile"/>
    </android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
