第一步

<RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".MainActivity"><android.support.v4.view.ViewPagerandroid:id="@+id/viewPager"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center"><android.support.v4.view.PagerTitleStripandroid:id="@+id/PagerTitleStrip"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="top"></android.support.v4.view.PagerTitleStrip></android.support.v4.view.ViewPager></RelativeLayout>

第二步建立三个tab页，用最简单的线性布局即可。
