어댑터는 액티비티 클래스의 설정 데이터 세트의 환경 설정에서 드리려고 먼저 얻을 데이터 같은 것을을 좋아하고 배열 목록으로 설정 목록 -로 설정입니다 전망. listview-

@Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.songs_list); 
     list = new ArrayList<String>(); 
     lv=(ListView)findViewById(R.id.listView1); 

     sPrefs=PreferenceManager.getDefaultSharedPreferences(getApplicationContext()); 
     listArraySet=new HashSet<String>(); 
     listArraySet=sPrefs.getStringSet(name1,new HashSet<String>()); 

     list=new ArrayList<String>(listArraySet); 
     ArrayAdapter<String> ao=new ArrayAdapter<String>(this, R.layout.songs_list_item, R.id.songTitle, list); 
     lv.setAdapter(ao); 

     //-------------------------CLICK ON LIST ITEM_----------------------- 
     lv.setOnItemClickListener(new OnItemClickListener() { 

      @Override 
      public void onItemClick(AdapterView<?> parent, View view, 
        int position, long id) { 
       int index = parent.getPositionForView(view);
