Well since you'll be using a ViewPager you don't have to think about the region which is swipeable since the height / width of the ViewPager determines this.
Layout example:
<?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"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- Static content -->
<LinearLayout
android:id="@+id/ll_bottom"
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_alignParentBottom="true"
android:background="@color/holo_blue_light"
android:orientation="vertical" />
<!-- ViewPager Indicator -->
<com.viewpagerindicator.LinePageIndicator
android:id="@+id/view_pager_indicator"
android:layout_width="fill_parent"
android:layout_height="20dp"
android:layout_above="@id/ll_bottom"
android:background="@color/holo_orange_light"
app:lineWidth="10dp"
app:selectedColor="#fff"
app:strokeWidth="10dp"
app:unselectedColor="#888888" />
<!-- ViewPager containing fragments with different views -->
<android.support.v4.view.ViewPager
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="@id/view_pager_indicator"
android:layout_alignParentTop="true"
android:background="@color/holo_red_light" />
</RelativeLayout>
Result:

Explanation: In the blue region you place your static content which doesn't change like the Facebook-Button in your example. The orange region is used by the ViewPagerIndicator and finally the red region is the one of the ViewPager. As previously said only this area is swipeable.
