Setting an item to appear next to a recycler view keeps appearing on top

Question

I have this recyclerview in which I have an arrow at the end of it but the thing is, even though I have setup the constraints for the arrow to appear After the recyclerview, it keeps appearing on top of it. How can I fix this?

This is the layout:
