| * Delegate used to provide new implementation of a select few methods of {@link MenuInflater} |
| * <p/> |
| * Through the layoutlib_create tool, the original methods of MenuInflater have been |
| * replaced by calls to methods of the same name in this delegate class. |
| * <p/> |
| * The main purpose of the class is to get the view key from the menu xml parser and add it to |
| * the menu item. The view key is used by the IDE to match the individual view elements to the |
| * corresponding xml tag in the menu/layout file. |
| * <p/> |
| * For Menus, the views may be reused and the {@link MenuItem} is a better object to hold the |
| * view key than the {@link MenuView.ItemView}. At the time of computation of the rest of {@link |
| * ViewInfo}, we check the corresponding view key in the menu item for the view and add it |
