How to find the class of a checkbox that was clicked

I have a 'ChecklistItem' class that has the following properties:

private CheckBox checkBox;
private ImageButton noteButton;
private TextView vitalField;

I have an onClick Listener for my checkbox. Now the problem is, when I click on that checkbox and the OnClick() method gets called, how can I figure out what ChecklistItem that checkbox is a part of?

Whenever I click on a checkbox, I want to add the ChecklistItem that the checkbox is a part of to an array, but the OnClick() only knows about the checkbox that called it.

How can I get around this?
