this code generate compile time error unless you've closed ScrollView Tag also ScrollView can always get a one ViewGroup Like LinearLayout and ReleativeLayout as a child. — Arash GM, Feb 22 '15 at 11:25

Scroll view tag can have only one child element Put your content of scroll view in linear layout.

<ScrollView>
<LinearLayout>
.......
.......
.....

</LinearLayout>
</ScrollView>
