MultiViewPager

The MultiViewPager is an extension of the support-v4 library's ViewPager that allows the pages to be wider or narrower than the ViewPager itself. It takes care of aligning the pages next to each other, and always keeping the selected page centered.

Sample

Simply add the MultiViewPager into your layout:

<com.pixplicity.multiviewpager.MultiViewPager
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:matchChildWidth="@+id/child_view_to_match" />

Be sure to declare the app namespace:
xmlns:app="http://schemas.android.com/apk/res-auto"

Take note of the custom attribute matchChildWidth. This attribute should match an ID in the ViewPager's first child view. In the sample project, the layout of the pages is:

<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:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="${relativePackage}.${activityClass}" >

    <FrameLayout
        android:id="@+id/vg_cover"
        android:layout_width="200dp"
        android:layout_height="match_parent"
        android:layout_centerInParent="true" >

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:padding="16dp"
            android:background="@drawable/bg_page"
            android:scaleType="centerInside"
            android:src="@drawable/im_pixplicity"
            tools:ignore="ContentDescription" />
            
    </FrameLayout>

</RelativeLayout>

The child view with ID @id/vg_cover will determine the width of the page. In this example, the width would be 200dp. In order to get this hooked up, we provide MultiViewPager with the reference to the child, @id/vg_cover:

<com.pixplicity.multiviewpager.MultiViewPager
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:matchChildWidth="@+id/vg_cover" />

In this way, it knows to size the pages according to the dimension of that View or ViewGroup.
