The document contains an XML layout for a ToggleButton within a RelativeLayout, designed to display 'ON' and 'OFF' states. The accompanying Java code in MainActivity sets up the ToggleButton and includes a listener to show a Toast message indicating the button's state when toggled. This implementation is part of an Android application that demonstrates basic UI interaction with a ToggleButton.
