The onCreate() method initially sets the layout, which was set to be a simple linear layout. This linear layout will be used as the container for the list view that is created from subsequent code. Once the linear layout has been located a node adapter and list view are created. The node adapter is added to the list view and the list view added to the linear layout.

As it is necessary to detect when a node is selected from the list displayed in the list view, a list view click listener needs to be added to listen for click events. A click event handler method is attached to the listener. This onItemClick method creates a new intent, creates a message object, and then starts the node detail activity, sending the created intent, which fundamentally contains the node selected from the list view.
