Scroll views in framelayout over z-axis

Question

I am trying to create a view I found on "developer.android.com", namely the top left one on the following image (I am not allowed to post images):

Layout from developer.android.com

It looks like one can choose between different 'cards' which are layered on top of each other.

I found that a FrameLayout will layer multiple child views, so I created the view in following way:

    <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" 
    >

    <LinearLayout
        android:layout_width="190dp"
        android:layout_height="230dp"
        android:layout_marginLeft="110dp"
        android:layout_marginTop="100dp"
        android:background="#FF0000"
        android:orientation="horizontal" >
    </LinearLayout>

    <LinearLayout
        android:layout_width="190dp"
        android:layout_height="230dp"
        android:layout_marginLeft="70dp"
        android:layout_marginTop="140dp"
        android:background="#00FF00"
        android:orientation="horizontal" >
    </LinearLayout>

    <LinearLayout
        android:layout_width="190dp"
        android:layout_height="230dp"
        android:layout_marginLeft="30dp"
        android:layout_marginTop="180dp"
        android:background="#0000FF"
        android:orientation="horizontal" >
    </LinearLayout>
</FrameLayout>

This will give the image of multiple views layered, but I don't know how to cycle through the different views. I tried looking for scrolling over the z-axis in a FrameLayout, but this did not give me any helpful results.

So my question is: How can I create a layout which allows scrolling through the child views over the z-axis by swiping the screen? Thank you in advance.

It looks like one can choose between different 'cards' which are layered on top of each other.

Android has a StackView widget that offers this UI. You tend to see it more in app widgets, as typical Android app widgets like Photo Gallery and YouTube employ a StackView.

Here is a sample project demonstrating the use of a StackView in a traditional UI, not in an app widget.
