プレイリストにアーティストを追加しようとしていますが、アダプターをカスタマイズできません

Question

ボタンを追加して情報を表示して共有しようとしていますが、その操作方法はわかりません。

これはMainActivityのコードです：

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    lv = (ListView) findViewById(R.id.lvPlaylist); 
    final ArrayList<File> mySongs = findSongs(Environment.getExternalStorageDirectory()); 
    items = new String[mySongs.size()]; 
    for (int i = 0; i < mySongs.size(); i++) { 
     items[i] = mySongs.get(i).getName().toString().replace(".mp3", "").replace(".wav", ""); 
    } 
    final ArrayAdapter<String> adp = new ArrayAdapter<String>(getApplicationContext(), R.layout.song_layout, R.id.textView, items); 

    lv.setAdapter(adp); 

    lv.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) { 
      startActivity(new Intent(getApplicationContext(), Player.class).putExtra("pos", position).putExtra("songlist", mySongs));    
     } 
    }); 
} 
public ArrayList<File> findSongs(File root) { 
    ArrayList<File> al = new ArrayList<File>(); 
    File[] files = root.listFiles(); 

    for (File singleFile : files) { 
     if (singleFile.isDirectory() && !singleFile.isHidden()) { 
      al.addAll(findSongs(singleFile)); 
     } else { 
      if (singleFile.getName().endsWith(".mp3") || singleFile.getName().endsWith(".wav")) {    
       al.add(singleFile); 
      } 
     } 
    } 
    return al; 
}
