RelativeLayout doesn't locate well in ConstraintLayout

I think I did everything true but the RelativeLayout in ConstraintLayout don't do what i command. When i add something under the RelativeLayout it supposed to be smaller and make room to other items but it doesn't matter what i do, it always push them out of the screen.

The left and right arrows should be below of RelativeLayout and adView should be below of arrows.

I am open the any kind of advice. Thanks.

I prefer to use whole Constraint Layout in your xml. Checkout below xml, hope the same what you want to design.
