次のサウンドを再生する前に、メディアプレーヤーがサウンドの再生を停止するようにしようとしています。そのため、音は互いに透過しません。初めてのアプリなので、響板を作ることから始めようと思いました。

これは私が今持っているものです:

    final MediaPlayer mediaPlayer = new MediaPlayer();
    // import sound files
    final MediaPlayer sound01 = MediaPlayer.create(this, R.raw.sound01);
    final MediaPlayer sound02 = MediaPlayer.create(this, R.raw.sound02);
    final MediaPlayer sound03 = MediaPlayer.create(this, R.raw.sound03);
    final MediaPlayer sound04 = MediaPlayer.create(this, R.raw.sound04);
    final MediaPlayer sound05 = MediaPlayer.create(this, R.raw.sound05);
    final MediaPlayer sound06 = MediaPlayer.create(this, R.raw.sound06);
    final MediaPlayer sound07 = MediaPlayer.create(this, R.raw.sound07);
    final MediaPlayer sound08 = MediaPlayer.create(this, R.raw.sound08);
    final MediaPlayer sound09 = MediaPlayer.create(this, R.raw.sound09);
    final MediaPlayer sound10 = MediaPlayer.create(this, R.raw.sound10);
    final MediaPlayer sound11 = MediaPlayer.create(this, R.raw.sound11);
    final MediaPlayer sound12 = MediaPlayer.create(this, R.raw.sound12);
    final MediaPlayer sound13 = MediaPlayer.create(this, R.raw.sound13);
    final MediaPlayer sound14 = MediaPlayer.create(this, R.raw.sound14);
    final MediaPlayer sound15 = MediaPlayer.create(this, R.raw.sound15);
    final MediaPlayer sound16 = MediaPlayer.create(this, R.raw.sound16);
    final MediaPlayer sound17 = MediaPlayer.create(this, R.raw.sound17);
    final MediaPlayer sound18 = MediaPlayer.create(this, R.raw.sound18);
    final MediaPlayer sound19 = MediaPlayer.create(this, R.raw.sound19);
    final MediaPlayer sound20 = MediaPlayer.create(this, R.raw.sound20);
    final MediaPlayer sound21 = MediaPlayer.create(this, R.raw.sound21);
    final MediaPlayer sound22 = MediaPlayer.create(this, R.raw.sound22);
    final MediaPlayer sound23 = MediaPlayer.create(this, R.raw.sound23);
    final MediaPlayer sound24 = MediaPlayer.create(this, R.raw.sound24);
    final MediaPlayer sound25 = MediaPlayer.create(this, R.raw.sound25);


    // play sound files on clicks
    Button s01 = (Button) findViewById(R.id.btn1_1); 
    s01.setText(this.getString(R.string.button1_1));
    s01.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            try {
                sound01.prepare();
            } catch (IllegalStateException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            mediaPlayer.stop();
            sound01.start();                
            }

    });
    registerForContextMenu(s01);

前もって感謝します!
