| * view was added directly to the window manager) and needs to show |
| * context menus, it will use this class. |
| * <p> |

| * and optionally populate it with any of your custom items. Finally, |
| * call {@link #showDialog(View, IBinder)} which will populate the menu |
| * with a view's context menu items and show the context menu. |
