How to do two actions on one button?

Question

Android

There is a simple application that launches an audio track at the touch of a button. Is it possible to make it so that when the same button is pressed, the image also opens? (the sound should also start playing).
I am attaching the code:
package com.example.user.myapplication;

import android.media.MediaPlayer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;

public class Calc extends AppCompatActivity {
    MediaPlayer player;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_calc);
    }
    public void play (View v) {
        if (player == null) {
            player = MediaPlayer.create (this, R.raw.song);
        }

        player.start();
    }

}

Ps I ask for more details, because the teapot (

Answer 1

Create a method for displaying an image and add its launch to the method void play(View v);

public void play (View v) {
        if (player == null) {
            player = MediaPlayer.create (this, R.raw.song);
        }

        player.start();
        
        showImage(R.drawable.id_image);
    }
    
    public void showImage(int idImage){
        findViewById(R.id.imageView).setImageResource(idImage);
    }

Attach a method to the button click event that will call the methods for both starting the sound and showing the picture.
