Checkboxes allow the user to select one or more options from a set. To create each checkbox option, create a
Checkbox in your layout.

Responding to Click Events
However, this example uses another approach. When the user selects a checkbox, the
CheckBox object receives an on-click event.
To define the click event handler for a checkbox, add the android:onClick attribute to the CheckBox element in your XML layout.
The value for this attribute must be the name of the method you want to call in response to a click event.
The activity hosting the layout must then implement the corresponding method.
However, this example uses another approach.
