appbar/toolbar overlapping view in constraint layout

I've six buttons in a vertical chain using a constraint layout. In my emulator it looks fine. You can ignore the two buttons on either side. I added them for perspective.

when I put the app on the the actual corresponding device I get a very different view. The toolbar overlaps my top button and the nav bar overlaps my bottom button.

I've read were the emulator isn't always correct. Given that, how can I account for the height of the toolbar and navigation bar in my constraint layout. Below is my xml. The six buttons are named x21 to x26 in my xml below. I apologize for the length of it. Is there a way to fix this in my xml or do I need to calculate the toolbar and nav bar height in my code and update the margin of the top and bottom button. If I need to do this in my code how would I do this. Or might there be another approach I'm grateful for any advice. Thanks

At the top where the ConstraintLayout is first set up add the last line from below T:

<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"    
    app:layout_behavior="@string/appbar_scrolling_view_behavior"

You need to change app:layout_constraintTop_toTopOf="parent" to

app:layout_constraintTop_toBottomOf="@id/coordinator_layout".

When you provide constraint as parent, it takes your parent layout container, which includes the toolbar as well. Instead you want to constraint it below the toolbar.

I think u mean action bar. Try to add action bar margin to the root element of your XML.

 android:paddingTop="?android:attr/actionBarSize"
