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);

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{
