Hi, I am trying to display the list of songs using array adapters. But the problem is i couldnt display the list and only empty screen with preset background is showing up. Here's the code...All the thee are seperate classes... Plz help me...

public class SongsAdapter extends ArrayAdapter<SongsList>{
private Context context;
TextView tvTitle;
TextView tvMovie;
TextView tvSinger;
String s;


    public SongsAdapter(Context context, int resource,
            int textViewResourceId, String title) {
        super(context, resource, textViewResourceId);
        this.context=context;
    }


public View getView(int position, View convertView, ViewGroup parent) {
    final int i=position;   

    List<SongsList> listSongs = new ArrayList<SongsList>();
    String title = listSongs.get(i).gettitleName().toString();

    String album = listSongs.get(i).getmovieName().toString();
    String artist = listSongs.get(i).getsingerName().toString();
    String imgal = listSongs.get(i).gettitleName().toString();

    LayoutInflater inflater = ((Activity) context).getLayoutInflater();
    View v = inflater.inflate(R.layout.row, null); 
    tvTitle=(TextView)v.findViewById(R.id.text2);
    tvMovie=(TextView)v.findViewById(R.id.text3);
    tvSinger=(TextView)v.findViewById(R.id.text1);
    tvTitle.setText(title);
    tvMovie.setText(album);
    tvSinger.setText(artist);

    final ImageView im=(ImageView)v.findViewById(R.id.image);
        s="http://www.gorinka.com/"+imgal;
         String imgPath=s;
        AsyncImageLoaderv asyncImageLoaderv=new AsyncImageLoaderv();
        Bitmap cachedImage = asyncImageLoaderv.loadDrawable(imgPath, new AsyncImageLoaderv.ImageCallback() {
            public void imageLoaded(Bitmap imageDrawable, String imageUrl) {

                im.setImageBitmap(imageDrawable);
           }
          });
         im.setImageBitmap(cachedImage);

       return v;

}   
 public class imageloader implements Runnable{

        private String ss;
        private ImageView im;

         public imageloader(String s,  ImageView im) {
             this.ss=s;
             this.im=im;
             Thread thread = new Thread(this);
             thread.start(); 
            }
        public void run(){
             try {

                 HttpGet httpRequest = null;            
                  httpRequest = new HttpGet(ss);
                  HttpClient httpclient = new DefaultHttpClient();
                    HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);
                    HttpEntity entity = response.getEntity();
                    BufferedHttpEntity bufHttpEntity = new BufferedHttpEntity(entity);
                     InputStream is = bufHttpEntity.getContent();

                     Bitmap bm = BitmapFactory.decodeStream(is);
                     Log.d("img","img");

                     is.close();
                     im.setImageBitmap(bm);

             } catch (Exception t) {
                Log.e("bitmap url", "Exception in updateStatus()", t);

            }

     } 
 }

public class SongsList {

private String titleName;
private String movieName;
private String singerName;
private String imagePath;
private String mediaPath;

// Constructor for the SongsList class public SongsList(String titleName, String movieName, String singerName,String imagePath,String mediaPath ) { super(); this.titleName = titleName; this.movieName = movieName; this.singerName = singerName; this.imagePath = imagePath; this.mediaPath = mediaPath; }
