In the resulting Create New Class dialog, name the class ToolbarFragment, change the Kind setting to Class and click on OK to create the new class. From the resulting menu, select the New -> Kotlin File/Class option. Add a class for this purpose to the project by unfolding the app -> java folder in the Project tool window and right-clicking on the package name given to the project when it was created (in this instance ).

In the resulting dialog, name the layout toolbar_fragment and change the root element to RelativeLayout before clicking on OK to create the new resource file. Once located, right-click on the layout entry and select the New -> Layout resource file menu option as illustrated in Figure 37-1: This user interface will, of course, reside in an XML layout file so begin by navigating to the layout folder located under app -> res in the Project tool window. The next step is to create the user interface for the first fragment that will be used within our activity.
