Step 1. First, create an activity_main.xml contains a button named my_button

Step 2. Then take header_menu.xml under res/menu:

Step 3. Finally, in MainActivity.kt use it like:

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        my_button.setOnClickListener {
             showPopup(my_button)
          }
    }

    private fun showPopup(view: View) {
        val popup = PopupMenu(this, view)
        popup.inflate(R.menu.header_menu)

        popup.setOnMenuItemClickListener(PopupMenu.OnMenuItemClickListener { item: MenuItem? ->

            when (item!!.itemId) {
                R.id.header1 -> {
                    Toast.makeText(this@MainActivity, item.title, Toast.LENGTH_SHORT).show()
                }
                R.id.header2 -> {
                    Toast.makeText(this@MainActivity, item.title, Toast.LENGTH_SHORT).show()
                }
                R.id.header3 -> {
                    Toast.makeText(this@MainActivity, item.title, Toast.LENGTH_SHORT).show()
                }
            }

            true
        })

        popup.show()
    }
