First, you need to create a layout file 

Activity_main.xml

<?xml version="1.0" encoding="utf-8"?>

<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">



    <android.support.v4.view.ViewPager

        android:layout_above="@id/tab_layout"

        android:id="@+id/view_pager"

        android:layout_width="match_parent"

        android:layout_height="match_parent"

        app:layout_behavior="@string/appbar_scrolling_view_behavior" />





    <android.support.design.widget.TabLayout

        app:tabTextAppearance="@style/MineCustomTabText"

        android:id="@+id/tab_layout"

        android:layout_alignParentBottom="true"

        android:layout_width="match_parent"

        android:layout_height="50dp"

        android:background="@color/colorPrimary"

        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>



</RelativeLayout>
