Collapsing Toolbar Like Google Play Store

Question

I want to implement a collapsing toolbar like google Play Store. I have achieved functionality somewhat but that is only working for portrait Screen. Here is a sample of screenshot of what i was able to do.

Now what i want to do is when i change my device orientation to LandScape mode it should look Exactly Like This.

So what my main question is how to handle these orientation changes. Is there any official android component available that can do this kind of thing or I will have to Z-index my Layouts to achieve this kind of Layout behavior. Please note that I want the layout to be exactly like this with Margins on Both Sides and Z-indexing on top of picture also the scrolling behavior needs to be exactly like Google Play Store.

I am attaching my sample xml that I have written so far.

Answer 1

In this pretty similar issue: collapsing toolbar layout like google play store, you would find an answer as below:

View inside CollapsingToolbarLayout no need to set app:layout_scrollFlags. No effect. Base on my code, change app:layout_scrollFlags in CollapsingToolbarLayout to app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed" and set minHeight for it.

As your toolbar is "pin", so enterAlwaysCollapsed will call it when you scroll down.

<android.support.design.widget.CoordinatorLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusableInTouchMode="true">

<android.support.design.widget.AppBarLayout
    android:id="@+id/appBarLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fitsSystemWindows="true">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/seffafCollapsingToolbarLayout"
        android:layout_width="match_parent"
        android:layout_height="240dp"
        android:minHeight="?attr/actionBarSize"
        app:expandedTitleMarginEnd="164dp"
        app:expandedTitleMarginStart="148dp"
        app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed">

        <ImageView
            android:id="@+id/header"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/haber_icerik_resim"
            android:fitsSystemWindows="true"
            android:scaleType="centerCrop"
            app:layout_collapseMode="parallax" />

        <android.support.v7.widget.Toolbar
            android:id="@+id/haber_toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:theme="@style/ToolbarColoredBackArrow"
            app:layout_collapseMode="pin"/>

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

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


<android.support.v7.widget.RecyclerView
    android:id="@+id/newsRecyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="vertical"
    android:clickable="true"
    android:background="@color/mainBackground"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />

In the comment to that post, you would find also a hint:

add app:contentScrim="?attr/colorPrimary" to your collapsingtoolbarlayout. It is no need two toolbars to implement this effect

EDIT: Here you would find an interview with a guy responsible for Google Play Store, he's talking about how he build design in Play Store App:
