Java code

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.PopupMenu;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
    Button button;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button = (Button) findViewById(R.id.clickBtn);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                PopupMenu popupMenu = new PopupMenu(MainActivity.this, button);
                popupMenu.getMenuInflater().inflate(R.menu.popup_menu, popupMenu.getMenu());
                popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    @Override
                    public boolean onMenuItemClick(MenuItem menuItem) {
                        Toast.makeText(MainActivity.this, "You Clicked " + menuItem.getTitle(), Toast.LENGTH_SHORT).show();
                        return true;
                    }
                });
                popupMenu.show();
            }
        });
    }
}

1. Start a New Project.
2. Open the activity main.xml file. In this step, we'll add a key on the keyboard to the characteristics suggest and name it clickBtn. Before we go any further, let's add some colour attributes to the app bar to make it more appealing. Add the following colour attributes to app > res > values > colors.xml. <resources> <color name="colorPrimary">#0F9D58</color><color name="colorPrimaryDark">#16E37F</color><color name="colorAccent">#03DAC5</color></resources>
3. Make a menu directory and a menu file. First, we'll make a menu director that will house the menu file. Go to app > res > right-click > New > Android Commodity Directory and enter a name for the directory and a resource type in the menu.
4. Used this MainActivity.java file, We will get the reference to the Button and initialise it in the MainActivity.java file. Add onClick behaviour towards the button and expand its popup menu.
5. We then refer to and initialise the button, as well as assign onClick behaviour to it.
6. The popup menu is then initialised, and the reference is set as the current context. Then, from the popup menu.xml file, inflate the popup menu.
7. The Toast notification on menu item was then selected. The popup menu is then displayed.
