PlayListAdapter.java

public class PlayListAdapter extends ArrayAdapter<Song> { 

    Context context; 
    int layoutResourceId; 
    Song[] data = null; 
    SongHolder holder = null; 
    ConnectionWrapper connectionWrapper; 

    public PlayListAdapter(Context context, int layoutResourceId, Song[] data) { 
     super(context, layoutResourceId, data); 
     this.context = context; 
     this.layoutResourceId = layoutResourceId;   
     this.data = data; 
    } 

    @Override

     View row = convertView;  

     if(row == null) 
     { 
      LayoutInflater inflater = LayoutInflater.from(context); 
      row = inflater.inflate(layoutResourceId, parent, false); 

      holder = new SongHolder(); 
      holder.songName = (TextView)row.findViewById(R.id.songName_text); 
      holder.score = (TextView)row.findViewById(R.id.score_text); 
      holder.likeButton = (ImageButton)row.findViewById(R.id.button_like); 
      holder.likeButton.setOnClickListener(new View.OnClickListener(){ 
       @Override 
       public void onClick(View v){ 
        Runnable r = new Runnable() { 
         public void run() { 
          try { 
           //get the SongHolder#songName of the item to which belongs the clicked button 
          } catch (IOException e) { 
           e.printStackTrace(); 
          } 
         } 
        }; 
        new Thread(r).start(); 
       } 
      }); 

      row.setTag(holder); 
     } 
     else 
     { 
      holder = (SongHolder)row.getTag(); 
     } 

     Song song = data[position]; 
     holder.songName.setText(String.valueOf(song.getSongName())); 
     holder.score.setText(String.valueOf(song.getScore())); 

     return row; 
    } 

    class SongHolder{ 
     TextView songName; 
     TextView score; 
     ImageButton likeButton; 

    } 
}

无需使用线程内ClickListener
只需使用 -

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    View row = convertView;  

    if(row == null) 
    { 
     LayoutInflater inflater = LayoutInflater.from(context); 
     row = inflater.inflate(layoutResourceId, parent, false); 

     holder = new SongHolder(); 
     holder.songName = (TextView)row.findViewById(R.id.songName_text); 
     holder.score = (TextView)row.findViewById(R.id.score_text); 
     holder.likeButton = (ImageButton)row.findViewById(R.id.button_like); 

     row.setTag(holder); 
    } 
    else 
    { 
     holder = (SongHolder)row.getTag(); 
    } 

    Song song = data[position]; 
    holder.songName.setText(String.valueOf(song.getSongName())); 
    holder.score.setText(String.valueOf(song.getScore())); 

    holder.likeButton.setOnClickListener(new View.OnClickListener(){ 
      @Override 
      public void onClick(View v){ 
       // TextView 
       TextView tvSongName = holder.songName; 
       // if you want to get song name 
       String songName = String.valueOf(song.getSongName()); 
       Log.v("SongName", "" +songName); 
      } 
     }); 

    return row; 
}
