I was trying to make a lower navigation bar and because the views where a lot I needed to use a scroll view but the problem is that the last element in the scroll view doesn't appear because of the navigation bar.
so what can I do to make last element appear??
my xml code is :

```
<?xml version="1.0" encoding="utf-8"?>

                android:textSize="14sp" />

        </LinearLayout>

</RelativeLayout>

```

so how can I make the last element in the scroll view because the navigaion bar is blocking it (it's in the front of it so the last element doesn't show.
