Recycler view with CollapsingToolbarLayout dosent work properly

Im using a CollapsingToolbar Layout and a recycler below it, what i want is that when i start scrolling in the recylcer view the toolbar changes itself along with it . if i scroll up the toolbar gets small and if i scroll down the toolbar comes down with it , but right now . whats happening is the recycler view and the toolbar are both acting independently of each other . the recycler view scrolls but nothing happens to the toolbar . i have to drag the toolbar up and down myself.
Here is my xml file.
<?xml version="1.0" encoding="utf-8"?>

app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior"

</android.support.design.widget.CoordinatorLayout>
</layout>
As you can see, the scrollbar still dosent go up by itself i have to drag it up manually even if the recycler view is at its bottom.

Replace this :
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="260dp"
app:layout_anchorGravity="bottom"
android:layout_marginTop="10dp"
android:layout_marginBottom="8dp"
android:fadeScrollbars="false"
android:scrollbars="vertical"
app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior"
>
</android.support.v7.widget.RecyclerView>
With this:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="260dp"
app:layout_anchorGravity="bottom"
android:layout_marginTop="10dp"
android:layout_marginBottom="8dp"
android:fadeScrollbars="false"
android:scrollbars="vertical">
</android.support.v7.widget.RecyclerView>
</RelativeLayout>

Change your AppBarLayout as below
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:expandedTitleTextAppearance="#style/TextAppearance.AppCompat.Title">
<ImageView
android:layout_width="match_parent"
android:layout_height="256dp"
app:layout_collapseMode="parallax"/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
app:layout_collapseMode="pin"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ToolBarStyle" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
and add app:layout_behavior="#string/appbar_scrolling_view_behavior" to your RecyclerView

Try this
<?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="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="180dp"
android:fitsSystemWindows="true"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/toolbar_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:toolbarId="#+id/toolbar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
Then dont forget to set your default toolbar
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Hope it helps.

collapsing toolbar not hide all

I would like to be able to do this I know it is a CollapsingToolbarLayout but I do not know how to make some idea stop at a distance, thanks for the help
the result I want to get

A simple example of implementing a collapsing toolbar.

Replace the image inside the ImageView as per your requirement which will be visible when the toolbar is expanded.
Rest of the view can be implemented in the NestedScrollView as per your requirement.

Don't forget to give below property to your FloatingActionButton
app:layout_anchor="#id/appBar"
app:layout_anchorGravity="bottom|end"
Try something like this: almost similar to your requirements

Thank you so much.

You use margin to set center your title.But using margin you can not set center.Please check below code. i think your title will be center.

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"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
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"

android:fitsSystemWindows="true"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" />
<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.v7.widget.RecyclerView
android:id="#+id/rv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:cacheColorHint="#android:color/transparent"

android:fadeScrollbars="true"
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

android:paddingTop="?attr/actionBarSize"

</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:layout_width="match_parent"
android:layout_height="#dimen/profile_header_height"

android:layout_width="match_parent"

app:expandedTitleMarginEnd="16dp"
app:expandedTitleMarginStart="20dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
