Implementing RecyclerView with collapsing toolbar layout

I'm trying to implement RecyclerView with collapsing toolbar,but i'm facing the problem as RecyclerView comes upward on collapsing toolbar.What i want to acheive that it should be down and comes up with collapsing toolbar.
please help? Below is the image what i'm currently getting the result.
here 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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="sccs.android.com.userinformation.HomeScreen">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapse_toolbar"
android:layout_width="match_parent"
android:layout_height="325dp"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#mipmap/nature2"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="top"
android:minHeight="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:layout_below="#+id/appbar"
android:padding="10dp"
android:id="#+id/my_recycler_view"
android:scrollbars="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</android.support.design.widget.CoordinatorLayout>

As #shijil showed.
You need to add this attribute to the RecyclerView (or any frame you want to have as the parent in your content):
app:layout_behavior="#string/appbar_scrolling_view_behavior"
This would be your RecyclerView's code (You don't need to add anything else besides the app:layout_behavior attribute):
<android.support.v7.widget.RecyclerView
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_below="#+id/appbar"
android:padding="10dp"
android:id="#+id/my_recycler_view"
android:scrollbars="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>

try this xml:
<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="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/my_recycler_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/appbar"
android:padding="10dp"
android:scrollbars="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:layout_height="325dp">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="?colorPrimary"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#mipmap/nature2"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_flexible_space"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

The Toolbar widget should be the last child of the CollapsingToolbarLayout in order

Use this xml.

NestedScrollView in CoordinatorLayout not showing overscroll

I have NestedScrollView with some texts and because that is in
CoordinatorLayout, when i scroll it to end of the NestedScrollView does not show overscroll effect, my guess is that when i reach end and try to scroll more i don't scroll nestedScrollView but i scroll CoordinatorLayout.

That design is wrong.
See:
<include
android:id="#+id/app_bar"
layout="#layout/news_app_bar"/>
You were including the layout in the CollapsingToolbarLayout which that should be in the NestedScrollView and not that CollapsingToolbarLayout.
Just do your stuffs in the NestedScrollView like this:
<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/activity_news_main_content"

<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clipToPadding="false"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<!--Here is the contents-->
<!--<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/activity_news_subtitle"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/activity_news_description"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>-->
</android.support.v4.widget.NestedScrollView>
<android.support.design.widget.AppBarLayout
android:id="#+id/activity_news_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbarmain"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary"
app:layout_collapseMode="pin"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/activity_news_collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
app:contentScrim="#color/colorPrimary"
app:layout_collapseMode="pin"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/activity_news_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"

app:layout_collapseParallaxMultiplier="0.7"
app:layout_scrollFlags="scroll|exitUntilCollapsed" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
And read this: CollapsingToolbarLayout
CollapsingToolbarLayout is a wrapper for Toolbar which implements a
collapsing app bar.

The problem is that when collapsed, the toolbar is appearing white (default gray color) as you can see in this image.
If I add background attribute to toolbar in xml, the toolbar is appearing even when not collapsed

CollapsingToolbar with different toolbar color

I am creating an activity with collapsing toolbar layout.
My toolbar has different color and with a parralax image.
What i want is to get I have different color of toolbar and when collpased,
the toolbar color will be change to another color.
Here's my XML.
<?xml version="1.0" encoding="utf-8"?>

</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_view_reviews"/>
ATM, i only getting this result.
The white is my toolbar. And it should be white at start,
and then after collapsing it would be chnage to other color.
I want the image to be under the toolbar.
Here is the sample of what am i doing..
In the first image, its not yet collpased.
And when the user scroll, the result will be the image 2

This is what you need, check the implementation and replace your things in it:

Here is the important code inside CollapsingToolbarLayout:

android Whatsapp like profile interface

I am looking for a way to create a profile interface like whatsapp:
I used collapsing toolbar and a recyclerView with inside CardView but my interface had a lot of problems.
When I scoll the recyclerView the items inside start scrolling when the toolbar is collapsed and the space of scrolling turn in the same space where before (when the toolbar was open) there was the image.
When the toolbar is collapsed there is the shadow.
This is the code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

</android.support.design.widget.CollapsingToolbarLayout>

android:paddingTop="?attr/actionBarSize"
android:scrollbars="vertical"
android:scrollbarThumbVertical="#drawable/scrollbar_color"
/>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
This is what happen:

Recycler view must be moved outside to AppBarLayout. and Try this way
<android.support.design.widget.CoordinatorLayout

xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/main_content"

<android.support.v7.widget.Toolbar
android:id="#+id/anim_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/rv"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:cacheColorHint="#android:color/transparent"
android:clipToPadding="false"
android:fadeScrollbars="true"
android:paddingTop="?attr/actionBarSize"
android:scrollbars="vertical"
android:scrollbarThumbVertical="#drawable/scrollbar_color"
/>
</android.support.design.widget.CoordinatorLayout>

Move your RecyclerView out of the AppBarLayout.

you could use NestedScrollView with CoordinatorLayout like this
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="#dimen/profile_header_height"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleMarginEnd="16dp"
app:expandedTitleMarginStart="20dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_collapseMode="parallax">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainView"
android:layout_width="match_parent"
android:layout_height="#dimen/profile_header_height"
android:background="#color/colorPrimary"
>
<ImageView
android:id="#+id/ivAvatar"
android:layout_width="#dimen/appbar_profile_pic_height_width"
android:layout_height="#dimen/appbar_profile_pic_height_width"
android:layout_centerHorizontal="true"
android:layout_marginTop="#dimen/profile_header_margin_top"
android:layout_marginLeft="?android:attr/listPreferredItemPaddingLeft"
android:contentDescription="#string/userPictureDes"
android:src="#drawable/ic_user_circle_white" />
<TextView
android:id="#+id/text_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true"
android:text="#string/example_user_name"
android:layout_centerHorizontal="true"
android:layout_below="#+id/ivAvatar"
android:layout_marginBottom="#dimen/list_text_padding_top"
android:layout_marginTop="5dp"
android:textColor="#android:color/white"
android:textSize="#dimen/profile_name_text_size" />
</RelativeLayout>
</FrameLayout>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="top"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.v4.widget.NestedScrollView
android:id="#+id/container_scroll_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
>
<!-- your view code here -->
</android.support.v4.widget.NestedScrollView>
