Switching Layouts in Android Studio

I have been working with a tutorial for Android Studio called Tutorial for Android: Quiz and Examples. It is straight forward and resourceful. One problem it does not explain how to change the App Layout from ConstraintLayout (the default) to RelativeLayout. Through searching, I have found the solution.

First start Android Studio. Once fully running, after updates, find Component Tree on the left halfway down the screen. Underneath that will be ConstraintLayout.

If using Windows, right-click on ConstraintLayout. Chose Convert view... out of the options displayed.

In the Convert view... window, you will; have the option of 5 Layouts. Chose RelativeLayout if that is your choice. I hope this helped.
