79.4 Designing the VideoPlayer Layout
The user interface for the main activity will consist solely of an instance of the VideoView class. Use the Project tool window to locate the app -> res -> layout -> activity_main.xml file, double-click on it, switch the Layout Editor tool to Design mode and delete the default TextView widget.
From the Widgets category of the Palette panel, drag and drop a VideoView instance onto the layout so that it fills the available canvas area as shown in Figure 79-1. Using the Attributes panel, change the layout_width and layout_height attributes to match_constraint and wrap_content respectively. Also, remove the constraint connecting the bottom of the VideoView to the bottom of the parent ConstraintLayout. Finally, change the ID of the component to videoView1.
