/**
 * <p>
 * This annotation is intended to be used on methods to receive events defined
 * by
 * {@link android.widget.CompoundButton.OnCheckedChangeListener#onCheckedChanged(android.widget.CompoundButton, boolean)}
 * after the checked state is changed on the targeted CompoundButton or subclass
 * of CompoundButton.
 * </p>
 * <p>
 * The annotation value should be one or several R.id.* fields that refers to
 * CompoundButton or subclasses of CompoundButton. If not set, the method name
 * will be used as the R.id.* field name.
 * </p>
 * <p>
 * The method MAY have multiple parameter:
 * </p>
 * <ul>
 * <li>A {@link android.widget.CompoundButton} (or a subclass) parameter to know
 * which view has targeted this event</li>
 * <li>An {@link boolean} to know the new state of the view.</li>
 * </ul>
 * <blockquote>
 * 
 * Example :
 * 
 * <pre>
 * @CheckedChange(<b>R.id.myButton</b>)
 * void checkedChangedOnMyButton(boolean isChecked, CompoundButton button) {
 * 	// Something Here
 * }
 * 
 * @CheckedChange
 * void <b>myButton</b>CheckedChanged(CompoundButton button) {
 * 	// Something Here
 * }
 * 
 * @CheckedChange
 * void <b>myButton</b>CheckedChanged(CheckBox button) {
 * 	// Something Here
 * }
 * 
 * @CheckedChange(<b>{R.id.myButton, R.id.myButton1}</b>)
 * void checkedChangedOnSomeButtons(CompoundButton button, boolean isChecked) {
 * 	// Something Here
 * }
 * 
 * @CheckedChange(<b>R.id.myButton</b>)
 * void checkedChangedOnMyButton() {
 * 	// Something Here
 * }
