Android Tabs at Bottom and Raised Center

This repository contains sample of setting android TabLayout at bottom and showing Fragment embedded in ViewPager. The trick is to add 5 Fragments to the ViewPager and 5 icons to tab layout. The center tab ie 3rd tab will serve a fake Fragment, it can be empty. We've a ImageButton on top of TabLayout aligned center and the bottom. That's button which will serve as raised center button. The magic happens very simply. You need to arrange them properly to stick tabs at bottom.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">
    <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:background="@drawable/tab_background"/>
    <android.support.v4.view.ViewPager
        android:id="@+id/main_tab_content"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_alignParentTop="true"
        android:layout_above="@id/tab_layout"
        android:background="@android:color/white" />
    <!-- Center and Bottom Aligned Button Acting as Raised Center Tab Item -->
    <ImageButton
        android:layout_width="80dp"
        android:layout_height="60dp"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:background="@drawable/center_tab_indicator"
        android:onClick="openCameraActivity"
        android:src="@drawable/camera" />
</RelativeLayout>
