        </LinearLayout>

        <ScrollView

            android:visibility="visible"
            android:layout_above="@+id/footer_layout"
            android:layout_below="@+id/search_layout">


        </ScrollView>

    </RelativeLayout>
</LinearLayout>

Using the scroll view layout to addView() the final layout in the UI is rendered and when setting the scroolview visibility to gone then only text field renders on ui and focus change is not happening.
