XListView上拉加载，下拉刷新

1.MainActivity页面

public class MainActivity extends AppCompatActivity {

private XListView xListView;
private int page;
private NewsAdapter adapter;
private String path = "http://www.xieast.com/api/news/news.php?page=%d";
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    page = 1;
    //获取资源ID
    xListView = findViewById(R.id.listview);
    //实例化适配器
    adapter = new NewsAdapter(this);
    xListView.setAdapter(adapter);
    //设置可以刷新加载
    xListView.setPullLoadEnable(true);
    xListView.setPullRefreshEnable(true);
    //设置监听
    xListView.setXListViewListener(new XListView.IXListViewListener() {
        @Override
        public void onRefresh() {
            page = 1;
            initData();
        }

        @Override
        public void onLoadMore() {
            initData();
        }
    });
    initData();
}
//得到数据并添加适配器
public void initData(){
    NetUtil.getJson(String.format(path, page), NewsBean.class, new NetUtil.CallBack<NewsBean>() {
        @Override
        public void sucess(NewsBean o) {
            if(page == 1){
                adapter.setdata(o.getData());
            }else{
                adapter.adddata(o.getData());
            }
            page++;
            //停止刷新加载
            xListView.stopRefresh();
            xListView.stopLoadMore();

        }
    });
}
}

2.多条目适配器

public class NewsAdapter extends BaseAdapter {
    private Context context;
    private List<NewsBean.DataBean> list;

public NewsAdapter(Context context) {
    this.context = context;
    list = new ArrayList<>();
}

public void setdata(List<NewsBean.DataBean> lists){
    list.clear();
    list.addAll(lists);
    notifyDataSetChanged();
}

public void adddata(List<NewsBean.DataBean> lists){
    list.addAll(lists);
    notifyDataSetChanged();
}


@Override
public int getCount() {
    return list.size();
}

@Override
public NewsBean.DataBean getItem(int position) {
    return list.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

private final int TYPE_COUNT = 2;
private final int TYPE_ONE = 0;
private final int TYPE_TWO =1;
@Override
public int getViewTypeCount() {
    return TYPE_COUNT;
}

@Override
public int getItemViewType(int position) {
    if(list.get(position).getThumbnail_pic_s02() == null){
        return TYPE_ONE;
    }else{
        return TYPE_TWO;
    }

}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    if(getItemViewType(position) == TYPE_ONE){
        ViewHolder holder;
        if(convertView == null){
            convertView = LayoutInflater.from(context).inflate(R.layout.item,parent,false);
            holder = new ViewHolder();
            holder.textView = convertView.findViewById(R.id.textView);
            holder.imageView = convertView.findViewById(R.id.imageView);
            convertView.setTag(holder);
        }else{
            holder = (ViewHolder) convertView.getTag();
        }
        holder.textView.setText(getItem(position).getTitle());
        ImageLoader.getInstance().displayImage(getItem(position).getThumbnail_pic_s(),holder.imageView);
    }else{
        NewsHolder holder;
        if(convertView == null){
            convertView = LayoutInflater.from(context).inflate(R.layout.items,parent,false);
            holder = new NewsHolder();
            holder.textView = convertView.findViewById(R.id.textView2);
            holder.imageView = convertView.findViewById(R.id.imageView2);
            holder.imageView2 = convertView.findViewById(R.id.imageView3);
            holder.imageView3 = convertView.findViewById(R.id.imageView4);
            convertView.setTag(holder);
        }else{
            holder = (NewsHolder) convertView.getTag();
        }
        holder.textView.setText(getItem(position).getTitle());
        ImageLoader.getInstance().displayImage(getItem(position).getThumbnail_pic_s(),holder.imageView);
        ImageLoader.getInstance().displayImage(getItem(position).getThumbnail_pic_s02(),holder.imageView2);
        ImageLoader.getInstance().displayImage(getItem(position).getThumbnail_pic_s03(),holder.imageView3);
    }
    return convertView;
}

class ViewHolder{
    TextView textView;
    ImageView imageView;
}
class NewsHolder{
    TextView textView;
    ImageView imageView,imageView2,imageView3;
}
}

使用XListview记得导入依赖！
