put the android:layout_height for the RelativeLayout android:id="@+id/relativeLayout1" as wrap_content instead of fill_parent

I don't know the exact reason and solution. but on trial and error it has worked.
I placed the "@+id/statusUpdateLayout" & "@+id/softKeysLayout" in one more relative layout like <relativelayout>
<linearlayout/>
<linearlayout/>
</relativelayout>

and removed the first linearlayout. I made scrollview as root element (just removing the first linear layout will make scrollview as root element) now its working fine.
