Final answer:
To view the layout in the graphical editor in Android Studio, click the 'Design' tab. This tab provides a visual design interface for constructing your app's UI, with options for drag-and-drop, previewing different screen sizes, API versions, and orientations.
Step-by-step explanation:
In Android Studio, to view the layout in the graphical editor, click the Design tab. This tab allows you to visually construct the layout for your app's user interface (UI) without writing XML code by hand. It provides a drag-and-drop interface where you can add different UI components from the palette and rearrange them in your layout.
Additionally, the Design tab has various features like viewing different screens sizes, changing API versions for preview, and seeing the layout on different orientations (portrait or landscape).
Android Studio also offers a Split mode option where you can see both the graphical layout editor and the XML code side by side. This is useful for learning how UI elements correspond to their XML definitions and for fine-tuning the layout more precisely.
To understand and work effectively on your projects, getting familiar with these tools and their functionalities within Android Studio is crucial.
