If you're looking for generated popup items with callbacks, used this.

Java

public static void popupMenu(final Context context, View anchor, final LinkedHashMap options){
        PopupMenu popupMenu = new PopupMenu(context, anchor);
        for(String key : options.keySet()){
            popupMenu.getMenu().add(key);
        }
        popupMenu.getMenuInflater().inflate(R.menu.popup_menu,popupMenu.getMenu());
        popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem menuItem) {

                options.get(menuItem.getTitle()).onClick();
                return true;
            }
        });

        popupMenu.show();
    }

public interface IPopupMenu{
        void onClick();
    }

XML

Example

LinkedHashMap menu_items = new LinkedHashMap<>();
menu_items.put("Item Name", new Utils.IPopupMenu() {
         @Override
         public void onClick() {
            //do your code
         }
});
menu_items.put("Clear Array", new Utils.IPopupMenu() {
         @Override
         public void onClick() {
            //clear array
         }
});

popupMenu(context,button,menu_items);
