title: Random sound play on button touch
body: <p>I want my button to play a different sound each time it is being touched.
  For now the button plays one sound when it is touched.</p>
  
  <p>I used the <code>onClickListener</code>,  and inside it I used the <code>MediaPlayer</code> to play the mp3 sound, the code is the following: </p>
  
  <pre><code>pressMe.setOnClickListener (new View.onClickListener (){
  
  @Override
  
  public void onClick (View v){
  
  sound = MediaPlayer.create (MainActivity.this,R.raw.popup);
  sound.start ();
  
  }
  });
  </code></pre>
  
  <p>What code should I use inside the <code>onClickListener</code>, so that if I placed 3 different sounds inside it, a different sound is randomly played each time the button is touched.</p>
  
  <p>Thank you in advance.</p>
