24 * <p>
25 * A checkbox is a specific type of two-states button that can be either
26 * checked or unchecked. A example usage of a checkbox inside your activity
27 * would be the following:
28 * </p>
29 *
30 * <pre class="prettyprint">
31 * public class MyActivity extends Activity {
32 *     protected void onCreate(Bundle icicle) {
33 *         super.onCreate(icicle);
34 *
35 *         setContentView(R.layout.content_layout_id);
36 *
37 *         final CheckBox checkBox = (CheckBox) findViewById(R.id.checkbox_id);
38 *         if (checkBox.isChecked()) {
39 *             checkBox.setChecked(false);
40 *         }
41 *     }
42 * }
43 * </pre>
