Question

I’m having problems implementing an asynchronous image loader to the following code. I read some posts around the web about it and I think I understand the logic behind it, but I seem to fail in implementing it.

The code bellow is what I use to simply load the images in my listview.

public class MyCustomAdapter extends ArrayAdapter<RSSItem> {
   Bitmap bm;

   public MyCustomAdapter(Context context, int textViewResourceId, List<RSSItem> list) {
      super(context, textViewResourceId, list); 
   }

   @Override
   public View getView(int position, View convertView, ViewGroup parent) {
      // TODO Auto-generated method stub
      BitmapFactory.Options bmOptions;
      bmOptions = new BitmapFactory.Options();
      bmOptions.inSampleSize = 1;
      bm = LoadImage(myRssFeed.getList().get(position).getDescription(), bmOptions);

      View row = convertView;

      if(row == null) {
         LayoutInflater inflater = getLayoutInflater();
         row = inflater.inflate(R.layout.rsslist, parent, false); 
      }

      TextView listTitle = (TextView)row.findViewById(R.id.listtitle);
      listTitle.setText(myRssFeed.getList().get(position).getTitle());
      ImageView listDescription = (ImageView)row.findViewById(R.id.listdescription);
      listDescription.setImageBitmap(bm);
      TextView listPubdate = (TextView)row.findViewById(R.id.listpubdate);
      listPubdate.setText(myRssFeed.getList().get(position).getPubdate());

      return row;
   }
}
