Android Studio – Button not visible during scroll view

I have a scroll view wrapping a LinearLayout , i have a button at the end of the layout , the entire layout is visible and scrollable but the button at the end is not visible , it becomes visible if i put it at first or make space for the button without the scroll view.

                android:textColor="@color/white" />

        </LinearLayout>
    </ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>

I have tried changing to androidx.appcompat.widget.AppCompatButton , use image button but still no avail,
I tried to give hard coded height and width still it’s not visible.

After some playing around i just found out that my last child is not visible be it button, text or any other

Any help is appreciated
