The text-based editor

Change the graphical editor to the text editor by clicking on the Text tab.

The Toolbar is the same as that on the graphical editor. The Preview window displays the layout but it cannot be changed. To do that, you should use the Design tab instead. The components are added to the layout using their XML declarations. The properties are also configured using XML declarations. Like the graphical editor, the text editor shows just the text view element inside the root layout.
