73.2 Adding a Picture-in-Picture Button
As currently designed, the layout for the VideoPlayer activity consists solely of a VideoView instance. A button will now be added to the layout for the purpose of switching into PiP mode. Load the activity_main.xml file into the layout editor and drag a Button object from the palette onto the layout so that it is positioned as shown in Figure 73-1:
Change the text on the button so that it reads “Enter PiP Mode” and extract the string to a resource named enter_pip_mode. Before moving on to the next step, change the ID of the button to pipButton and configure the button to call a method named enterPipMode.
