图像和文本分别在listview中显示-Android使用图像加载器

我正在尝试使用imageLoader通过url加载图像和文本时，在列表视图中填充图像和文本时，显示时在此处输入图片说明

这是我的代码

mall=getIntent().getStringArrayListExtra("text");
      mallpos=getIntent().getStringArrayListExtra("Ima");
      System.out.println("Images"+mallpos);

      System.out.println(mall.size());
      for(int i=0;i<mall.size();i++)
      {
          poss=mall.get(i);
          System.out.println("value"+poss);
          dto =new locationdto();
          dto.setMallname(poss);
          rou.add(dto);

      }
      System.out.println(mallpos.size());
      for(int i=0;i<mallpos.size();i++)
      {
          Ima=mallpos.get(i);
          System.out.println("value"+Ima);
          dto=new locationdto();
          dto.setImage(Ima);
          System.out.println("imaghe"+ dto.getImage());
          rou.add(dto);

      }

      lv=(ListView)findViewById(R.id.listm);


      System.out.println("Arraysize#############" + rou.size());
      System.out.println("Arraysize#############" + rou1.size());

      MaterialMasterAdapter adapteer =new MaterialMasterAdapter(MalllistActivity.this, rou);
      lv.setAdapter(adapteer);

这是我的适配器代码，我无法纠正错误

            child.setTag(mHolder);

        } else 
        {
            mHolder = (Holder) child.getTag();
        }

        dto=a1.get(pos);
        String url=dto.getImage();


        mHolder.txtitemid.setText(dto.getMallname());
        ImageLoader.getInstance().displayImage(url, mHolder.imageView);

        return child;
    }


    public class Holder 
    {
        TextView txtitemid,txtmat,txtqty,image;
        ImageView imageView;
    }
}

将两个arraylist合并为一个`

 if (mall.size()  != mallpos.size()) { // Too many names, or too many numbers
            // Fail
        }
        for (int i = 0; i < mall.size(); i++) { // Loop through every name/phone number combo
            array3.add(mall.get(i) + " " + mallpos.get(i)); // Concat the two, and add it
            v=mall.get(i);
            n=mallpos.get(i);
            dto =new locationdto();
              dto.setMallname(v);
              dto.setImage(n);

              rou.add(dto);

        }
