/**
 * <p>
 * This annotation is intended to be used on methods to receive events defined
 * by
 * {@link android.widget.TextView.OnEditorActionListener#onEditorAction(android.widget.TextView, int, android.view.KeyEvent)}
 * when an action is performed on the editor.
 * </p>
 * <p>
 * The annotation value should be one or several R.id.* fields that refers to
 * TextView or subclasses of TextView. 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.TextView} parameter to know which view has
 * targeted this event</li>
 * <li>An int parameter to get the actionId</li>
 * <li>A {@link android.view.KeyEvent} parameter</li>
 * </ul>
 * <p>
 * The return type of the method can be either <b>void</b> or <b>boolean</b>. In
 * case of <b>boolean</b>, the value returned from the annotated method will be
 * returned in the generated listener method (indicating event consumption). If
 * the annotated method is <b>void</b>, always <b>true</b> will be returned in
 * the listener method (so the event is consumed).
 * </p>
 * <blockquote>
 *
 * Examples :
 *
 * <pre>
 * &#064;EditorAction(<b>R.id.helloTextView</b>)
 * void onEditorActionsOnHelloTextView(TextView hello, int actionId, KeyEvent keyEvent) {
 * 	// Something Here
 * }
 * 
 * &#064;EditorAction
 * void <b>helloTextView</b>EditorAction(TextView hello) {
 * 	// Something Here
 * }
 * 
 * &#064;EditorAction(<b>{R.id.editText, R.id.helloTextView}</b>)
 * void onEditorActionsOnSomeTextViews(TextView tv, int actionId) {
 * 	// Something Here
 * }
 * 
 * &#064;EditorAction(<b>R.id.helloTextView</b>)
 * void onEditorActionsOnHelloTextView() {
 * 	// Something Here
 * }
 * 
 * &#064;EditorAction(R.id.helloTextView)
 * <b>boolean</b> onEditorActionsOnHelloTextView() {
 * 	// Something Here
 * 	<b>return false;</b>
 * }
 * </pre>
