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:

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);
