ScrollView doesn’t scroll to the bottom

The problem is android:layout_margin=”10dp” in RelativeLayout of SrcollView

Replace

 <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="10dp">

with

<RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="10dp" >
