package com.javatpoint.popupmenu;

So finally I found solution. When you want to anchor popupmenu to ActionItem in ActionBar you need to find view that renders ActionItem. Simple find view with findViewById() where id is same as id of your menu item in xml.

DISPLAYING POPUP:

public boolean onOptionsItemSelected(MenuItem item) {
        // ...
    
        View menuItemView = findViewById(R.id.menu_overflow); // SAME ID AS MENU ID
        PopupMenu popupMenu = new PopupMenu(this, menuItemView); 
        popupMenu.inflate(R.menu.counters_overflow);
        // ...
        popupMenu.show();
        // ...
        return true;
    }

<?xml version="1.0" encoding="utf-8"?>
    <menu xmlns:android="http://schemas.android.com/apk/res/android" >
    
         ....
    
         <item
        android:id="@+id/menu_overflow"
        android:icon="@drawable/ic_overflow"
        android:showAsAction="ifRoom"
        android:title="@string/menu_overflow"/>
    
         ....
    
    </menu>
