How to use viewpager inside collapsible toolbar?

Question

I am using Viewpager at the top of my layout and below that there is a frame layout which contains a recycler View. I want to collapse the viewpager when i scroll my recycler view so that it can be viewed full screen.

This is how my layout file looks like:

    <RelativeLayout 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:id="@+id/main_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/white"
android:orientation="vertical"
tools:context=".MainActivity">


<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

<android.support.v4.view.ViewPager
    android:id="@+id/pager_container"
    android:layout_width="match_parent"
    android:layout_height="180dp"
    android:layout_gravity="center_horizontal"
    android:layout_marginTop="?attr/actionBarSize" />

<FrameLayout
    android:id="@+id/content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@id/seperator"
    android:layout_marginTop="20dp" />
    </RelativeLayout>

I have attached the screenshort also for the same.

Using CoordinatorLayout you can do this.

Follow this 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:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:layout_scrollFlags="scroll|enterAlways|snap" />

        <android.support.design.widget.TabLayout
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:fillViewport="false" />

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

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

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="end|bottom"
        android:layout_margin="@dimen/fab_margin"
        android:src="@drawable/ic_done" />

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

As you can see in screenshot i posted, viewpager is at the top of the screen and i want to collapse it on scroll of below recycler view. The code you have sent as answer is having viewpager but it is outside collapsabletoolbar. — Abhishek, May 05 '16 at 05:42

Put your View Pager inside an Collapsing Toolbar layout and use coordinator layout.

Have a look at the link below. Understand it and start implementing. Any doubts feel free to ask me here.

Once you are done with that also have a look at below link.

Collapsing Toolbar and Fragment

EDITED:

First you need to compile

compile 'com.android.support:design:23.3.0'

and then here is the sample

<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">

    <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">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
                app:layout_collapseMode="pin" />
          <android.support.v4.view.ViewPager
            android:id="@+id/pager_container"
            android:layout_width="match_parent"
            android:layout_height="180dp"
            android:layout_gravity="center_horizontal"
            android:layout_marginTop="?attr/actionBarSize" />

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

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

I have edited it to make as simple for you as i could, Hope it helps

But in your code viewpager is outside the collipsingtoolbar. I want to collapse the view pager only. — Abhishek, May 05 '16 at 05:31
