Mediaplayer overlaps when the button is pressed several times

Question

I am making an app in Android Studio using MediaPlayer to use my audio clips, when I press a button, the audio plays correctly, when I press another one, the previous one stops and the new one starts, but if I press repeatedly the same button it starts to overlap, and when I hit the "back" button, only one of the audios stops while the others are still playing.

How could I do to avoid that, when pressing a button several times, it overlaps, and instead it "restarts" without overlapping.

Thank you!

Here´s my Java Code

The problem is a lot of MediaPlayer creations without any release. Please check the below code, it may help you to identify the right way.

private MediaPlayer mediaPlayer;
public void play(int rawSoundId){
    stop();
    mediaPlayer = MediaPlayer.create(this, rawSoundId);
    mediaPlayer.start();
}

public void pause() {
    if (mediaPlayer != null) {
        mediaPlayer.pause();
    }
}

public void stop() {
    if (mediaPlayer != null) {
        if (mediaPlayer.isPlaying()) {
            mediaPlayer.stop();
        }
        mediaPlayer.release();
        mediaPlayer = null;
    }
}

Just call play(R.raw.mezquitait) from your view functions.
