    The attributes android:textOn and android:textOff specify the text for the button when the button has been toggled on or off. The default values are "ON" and "OFF".

    When you specify this kind of method, which is used in your layout file with the {@code +android:onClick} +attribute, the method must be public, have a void return value, and +accept a single {@code android.view.View} parameter. When the system calls this method, it +passes the {@code android.view.View} that was clicked.

    In this example, the callback method checks the new state of the button, then shows a {@link android.widget.Toast} message that indicates the current state.
