how to implement play store Collapsing Toolbar Layout?

问题

* It's not a duplicate of collapsing toolbar layout like google play store

I want to scroll collapsingToolbarLayout down when recyclerView scrolled down and vice versa like below .gif image.

Any help will be appreciated.

I used different layout_scroll flag but it does not work at all.

and there is xml layout :

Change

app:layout_scrollFlags="scroll|enterAlways"

to

app:layout_scrollFlags="scroll|enterAlways|snap"

Use this

<RelativeLayout 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.design.widget.AppBarLayout
        android:id="@+id/id_toolbar_container"
        android:layout_width="match_parent"

        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:layout_collapseMode="pin"
            app:layout_scrollFlags="scroll|exitUntilCollapsed" />
    </android.support.design.widget.AppBarLayout>

    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/main_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/id_toolbar_container">

        <android.support.design.widget.AppBarLayout
            android:id="@+id/app_bar"
            android:layout_width="match_parent"

                android:layout_height="wrap_content"
                app:layout_scrollFlags="scroll|enterAlways">

                <android.support.design.widget.TabLayout
