첫 메이크업의 목록 또는 다음 노래를 통과 SDCARD에서 노래 목록의 배열을 사용하여 위치

coverFlow.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(CoverAdapterView<?> parent, View view, 
       int position, long id) { 
      // TODO Auto-generated method stub 

       playSong(list[position]); <--- 
     } 
    });
