Kotlin Android Popup Menu

Android Popup Menu is a list menu that appears vertically to the view. The popup menu appears below the view if there is room otherwise, appears above. Touching outside to popup menu makes it disappear.

Popup Menu provides actions that are related to the specific content, and it does not affect the corresponding content.

The PopupMenu.OnMenuItemClickListener interface receives the menu items click events if the items don't have their click listener.

Kotlin Android Popup Menu Example

In this example, we will add the popup menu items on a view (button). Clicking on the button shows the popup menu items on which we can perform the relevant action.

Create an android project and select the Basic Activity. This activity auto-generates codes for the menu.

  • popup_menu.xml

    Create a menu resource file named as popup_menu.xml in the menu directory. Add the item tag which creates the menu item for the popup menu.
