|------------------------------------------------------------------------------------------------------|
| [android.view.ContextMenu](https://developer.android.com/reference/kotlin/android/view/ContextMenu#) |
Extension of[Menu](https://developer.android.com/reference/kotlin/android/view/Menu)for context menus providing functionality to modify the header of the context menu.
Context menus do not support item shortcuts and item icons.
To show a context menu on long click, most clients will want to call[Activity.registerForContextMenu](https://developer.android.com/reference/kotlin/android/app/Activity.html#registerForContextMenu(android.view.View))and override[Activity.onCreateContextMenu](https://developer.android.com/reference/kotlin/android/app/Activity.html#onCreateContextMenu(android.view.ContextMenu,%20android.view.View,%20android.view.ContextMenu.ContextMenuInfo)).

Add a group of menu items corresponding to actions that can be performed for a particular Intent. The Intent is most often configured with a null action, the data that the current activity is working with, and includes either the[Intent.CATEGORY_ALTERNATIVE](https://developer.android.com/reference/kotlin/android/content/Intent.html#CATEGORY_ALTERNATIVE:kotlin.String)or[Intent.CATEGORY_SELECTED_ALTERNATIVE](https://developer.android.com/reference/kotlin/android/content/Intent.html#CATEGORY_SELECTED_ALTERNATIVE:kotlin.String)to find activities that have said they would like to be included as optional action. You can, however, use any Intent you want. See android.content.pm.PackageManager#queryIntentActivityOptions for more \* details on the caller, specifics, and intent arguments. The list returned by that function is used to populate the resulting menu items. All of the menu items of possible options for the intent will be added with the given group and id. You can use the group to control ordering of the items in relation to other items in the menu. Normally this function will automatically remove any existing items in the menu in the same group and place a divider above and below the added items; this behavior can be modified with the flags parameter. For each of the generated items[MenuItem.setIntent](https://developer.android.com/reference/kotlin/android/view/MenuItem#setIntent(android.content.Intent))is called to associate the appropriate Intent with the item; this means the activity will automatically be started for you without having to do anything else.

Add a new sub-menu to the menu. This item displays the given title for its label. To modify other attributes on the submenu's menu item, use[SubMenu.getItem()](https://developer.android.com/reference/kotlin/android/view/SubMenu#getItem()).
| | [SubMenu](https://developer.android.com/reference/kotlin/android/view/SubMenu)! | [addSubMenu](https://developer.android.com/reference/kotlin/android/view/Menu#addSubMenu(kotlin.Int,%20kotlin.Int,%20kotlin.Int,%20kotlin.Int))`(`groupId:` `[Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)`, `itemId:` `[Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)`, `order:` `[Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)`, `titleRes:` `[Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)`)`
