Image getting behind the background

I would like to place one image in front of another image. I'll explain better. I have a background and I want to put an image on the dividing line between RelativeLayout and ScrollView.

In the native android I have the option:

app:layout_anchorGravity="bottom|end"

That looks like this:

Let'ssupposethatinsteadofthaticonwouldputanimage.
