这里是我的abdominalfragment.java 更改此代码

ImageLoader imageLoader = AppController.getInstance().getImageLoader();
NetworkImageView thumbnail = (NetworkImageView)convertView.findViewById(R.id.gambar11);
// thumbnail image
thumbnail.setImageUrl(exerciseList.get(position).getGambar1(), imageLoader);

ImageLoader imageLoader = AppController.getInstance().getImageLoader();
NetworkImageView thumbnail1 = (NetworkImageView ) dialog.findViewById(R.id.gambar11);
thumbnail1.setImageUrl(exerciseList.get(position).getGambar1(), imageLoader);
