    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical"> 
    <android.support.v4.view.ViewPager  xmlns:android=
    "http://schemas.android.com/apk/res/android" 
        android:id="@+id/pager" 
        android:layout_width="match_parent" 
        android:layout_height="match_parent" /> 
 
    </LinearLayout>

    class MainActivity : BaseActivity(...
