stop playing audio when another one starts playing android studio Java

Question

I'm new to programming and android studio, and this is my first app. I used MediaPlayer in my code. And I can't make it so that when I click on one sound, the other stops and the play image changes. I want to make it so that when I click on the play button, other audio stops playing and the picture of play2 changes, etc.

You don't need to create 5 MediaPlayer to achieve your needs, try this :

public class Case1 extends AppCompatActivity {

    ImageView play, play2, play3, play4, play5;
    MediaPlayer mediaPlayer;
    private boolean isPlay, isPlay2, isPlay3, isPlay4, isPlay5;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_case1);

        mediaPlayer = new MediaPlayer();

        play = (ImageView) findViewById(R.id.play1);
        play.setOnClickListener(v -> {
            if (isPlay && mediaPlayer.isPlaying()) {
                mediaPlayer.pause();
                play.setImageResource(R.drawable.play_btn);
            } else {
                try {
                    mediaPlayer.reset();
                    mediaPlayer.setDataSource(getApplicationContext(), raw2Uri(R.raw.case1_1));
                    mediaPlayer.prepare();
                    mediaPlayer.start();
                    pauseAllPlayers();
                    play.setImageResource(R.drawable.pause_btn);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            isPlay = true;
