21.3 Summary
The Android Studio Layout Editor tool provides a visually intuitive method for designing user interfaces. Using a drag and drop paradigm combined with a set of property editors, the tool provides considerable productivity benefits to the application developer.
User interface designs may also be implemented by manually writing the XML layout resource files, the format of which is well structured and easily understood.
The fact that the Layout Editor tool generates XML resource files means that these two approaches to interface design can be combined to provide a “best of both worlds” approach to user interface development.
