想要使用SoundPool添加落子的音效！但是不知道该怎么实现？

我这样写貌似不行！

private SoundPool sp;
private int music;

@Override
protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_main);
   wuziqiPanel = (WuzhiqiPanel) findViewById(R.id.id_wuzhiqi);
   playMusic();
}

private void playMusic() {
   sp = new SoundPool(5, AudioManager.STREAM_SYSTEM,5);
   music = sp.load(this,R.raw.yx4,1);
   wuziqiPanel.setOnClickListener(listener);
}
private View.OnClickListener listener = new View.OnClickListener() {
   @Override
   public void onClick(View v) {
       sp.play(music, 1, 1, 0, 0, 1);
   }
};
