There are two options to customize screen layout. You can either use the drag-anddrop feature in Design view or manually edit the XML file in Text view. We are going to

in Listing 5-8 . This layout file acts as a container for other sub-layout files. As you can
see in Listing 5-8 , content_main is included in the activity_main.xml layout file.
