your layout contents exceeds viewport(screen height) of scrollview. in type of layout structure thing can set fixed height viewpager. can view viewpager content. try below code viewpager
<android.support.v4.view.viewpager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="300dp" android:layout_below="@id/tabs" />
