3). MainActivity.java: inflate the menu file and use PopUp class

package com.androidjava.popupmenudemo;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.PopupMenu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    Button PopUpButton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        PopUpButton= (Button) findViewById(R.id.popupButton);

        PopUpButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                PopupMenu popup=new PopupMenu(MainActivity.this,PopUpButton);

                popup.getMenuInflater().inflate(R.menu.popup_menu,popup.getMenu());

                popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    @Override
                    public boolean onMenuItemClick(MenuItem item) {

                        Toast.makeText(MainActivity.this,"Click Item:"+item.getTitle(),Toast.LENGTH_LONG).show();
                        return true;
                    }
                });

                popup.show();
            }
        });


    }
