* A checkbox is a specific type of two-states button that can be either * checked or unchecked. A example usage of a checkbox inside your activity * would be the following: *

* *
 * public class MyActivity extends Activity {
 *     protected void onCreate(Bundle icicle) {
 *         super.onCreate(icicle);
 *
 *         setContentView(R.layout.content_layout_id);
 *
 *         final CheckBox checkBox = (CheckBox) findViewById(R.id.checkbox_id);
 *         if (checkBox.isChecked()) {
 *             checkBox.setChecked(false);
 *         }
 *     }
 * }
 *
