 3     android:orientation="horizontal"
 4     android:layout_width="fill_parent" 
 5     android:layout_height="wrap_content"
 6     android:padding="5dp">
 7     <TextView
 8         android:layout_width="wrap_content"
 9         android:layout_height="wrap_content"
10         android:text="Country" />
11     <AutoCompleteTextView android:id="@+id/autocomplete"
