        @Override

        ViewHolder vh;
        Log.i("ee", position+" "+arg1);
        if(arg1==null)
        {
            arg1= mInflater.inflate(R.layout.newfile, null);
            vh=new ViewHolder();
            vh.Image=(ImageView) arg1.findViewById(R.id.imagelistIVimage);
            vh.Image.setLayoutParams(new LinearLayout.LayoutParams(200, 200));
            arg1.setTag(vh);
        }
        else
           vh=(ViewHolder)arg1.getTag();
        
        vh.Image.setImageResource(img[position]);
        return arg1;
        }
    }
   public class ViewHolder {
       ImageView Image;
     }
}
为什么我用logcat看arg1的内容
不管怎么拖动都是null?
