/**
 * <p>
 * This annotation is intended to be used on methods to receive events defined
 * by <code>OnPreferenceClickListener#onPreferenceClick(Preference)</code> when
 * the <code>Preference</code> has been clicked by the user.
 * </p>
 * <p>
 * This annotation only can be used inside
 * {@link org.androidannotations.annotations.EActivity EActivity} or
 * {@link org.androidannotations.annotations.EFragment EFragment} annotated
 * class, which is a subclass of {@link android.preference.PreferenceActivity
 * PreferenceActivity} or <code>PreferenceFragment(Compat)</code>, respectively.
 * </p>
 * <p>
 * The annotation value should be one or several of R.string.* fields. If not
 * set, the method name will be used as the R.string.* field name.
 * </p>
 * <p>
 * The method MAY have one parameter:
 * </p>
 * <ul>
 * <li>A {@link android.preference.Preference Preference} (or a subclass) or
 * <code>android.support.v7.preference.Preference</code> (or a subclass)
 * parameter to know which preference has been clicked</li>
 * </ul>
 * <blockquote>
 * 
 * Example :
 * 
 * <pre>
 * @PreferenceClick(<b>R.string.myPref</b>)
 * void clickOnMyPref() {
 * 	// Something Here
 * }
 * 
 * @PreferenceClick
 * void <b>myPref</b>PreferenceClicked(Preference preference) {
 * 	// Something Here
 * }
 * 
 * @PreferenceClick
 * void <b>myPref</b>PreferenceClicked(ListPreference preference) {
 * 	// Something Here
 * }
