Question

How to implement collapsing toolbar layout design like Google IO 2015 using Design Library

In Open Source Code of Google IO 2015, it is not implemented using Design Library (CoordinatorLayout, CollapsingToolbarLayout etc)

Google IO 2015 Session Details Layout

Note : In this the toolbar is at the bottom in upper section. I need the toolbar to be scrolling like this attached with the textview or any other view of upper section.

The source code of the app is available at https://github.com/google/iosched — ashkhn, Apr 03 '16 at 14:50
@akash93 That i know. I already specified using Design Library and in open source it is not implemented using Design Library. — Vipul Asri, Apr 03 '16 at 16:01
Have you tried moving the Toolbar out of the CollapsingToolbarLayout, but inside AppbarLayout? — GPack, Apr 05 '16 at 13:13

The code below will do what you want to do:

<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/appbar"
    android:layout_width="match_parent"
    android:layout_height="192dp"
    android:fitsSystemWindows="true"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        app:expandedTitleGravity="bottom|center_horizontal"
        app:contentScrim="@android:color/holo_blue_dark"
        app:expandedTitleMarginBottom="32dp"
        app:expandedTitleMarginEnd="64dp"
        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="@drawable/header"
            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.design.widget.AppBarLayout>

// The rest of the content goes here...

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