我将不胜感激任何帮助

ItemDetails.java

package com.devleb.expandablelistdemo3;

public class ItemDetails {

    String stad_name;
    String team1;
    String team2;
    String match_date;
    byte[] flags1;
    byte[] flags2;
    String group;

    public String getStad_name() {
        return stad_name;
    }

    public void setStad_name(String stad_name) {
        this.stad_name = stad_name;
    }

    public String getTeam1() {
        return team1;
    }

    public void setFlags1(byte[] flags1) {
        this.flags1 = flags1;
    }

    public void setFlags2(byte[] flags2) {
        this.flags2 = flags2;
    }

    public void setTeam1(String team1) {
        this.team1 = team1;
    }

    public String getTeam2() {
        return team2;
    }

    public void setTeam2(String team2) {
        this.team2 = team2;
    }

    public String getMatch_date() {
        return match_date;
    }

    public void setMatch_date(String match_date) {
        this.match_date = match_date;
    }

    public String getGroup() {
        return group;
    }

    public void setGroup(String group) {
        this.group = group;
    }

    String Name;
    int image;

    public String getName() {
        return Name;
    }

    public void setName(String name) {
        Name = name;
    }

    public int getImage() {
        return image;
    }

    public void setImage(int image) {
        this.image = image;
    }

}

这就是我现在写的如何从这里继续获取图片???

            this.context = context;
            itemdetailsList = list;
        }




    @Override

        if (convertView == null) {
            LayoutInflater inflater = (LayoutInflater) context

            convertView = inflater.inflate(R.layout.row_list_match_schedule, null);
        }

        TextView txtStadName = (TextView)convertView.findViewById(R.id.textLocation);
        txtStadName.setText(itemdetail.getStad_name());

        //flag1
        ImageView imgflag1 = (ImageView)convertView.findViewById(R.id.imageView1);
        imgflag1.







        return null;
    }
