接下来是Adapter类

其中轮播图适配器BannerAdapter省略

NewsAdapter，多列表，判断是否有Banner数据，有的话，集合数量+1。

package com.xxx.zkb2.adapter;

import android.os.Handler;
import android.os.Message;
import android.support.v4.view.ViewPager;

    BannerViewHolder bh;
    public NewsAdapter(MainActivity mainActivity) {
        this.mainActivity = mainActivity;
        newslist=new ArrayList<>();
        bannerlist=new ArrayList<>();
    }
    /**

    public void setNewsData(ArrayList<News.ResultBean> resultBeans) {
        newslist.clear();
        newslist.addAll(resultBeans);
        notifyDataSetChanged();
    }

    public void setbannerData(List<Banner.DataBean> dataBeans) {
        newslist.clear();
        bannerlist.addAll(dataBeans);
        notifyDataSetChanged();
    }
    private boolean hasBanner() {

        return bannerlist.size() > 0;
    }
    @Override
    public int getItemViewType(int position) {
        //有banner 且 position == 0 则是Banner数据
        //0代表banner,1代表新闻列表

        return hasBanner()&&position==0?0:1;
    }

    @Override
    public int getViewTypeCount() {
        return super.getViewTypeCount()+1;
    }

    @Override
    public int getCount() {
        //如果有Banner，则需要展示Banner数据，因此+1
        return newslist.size()+(hasBanner()?1:0);
    }

    @Override
    public Object getItem(int position) {
        if(hasBanner() && position == 0) {
            return null;
        }
        //如果有banner，第一条是Banner数据。因此真正的数据从position -1开始
        return newslist.get(hasBanner()?position-1:position);
    }

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
      if(getItemViewType(position)==0){//banner

       if(convertView==null){
           bh = new BannerViewHolder();
           convertView=View.inflate(mainActivity, R.layout.banner,null);
           bh.viewPager=convertView.findViewById(R.id.viewpager);
           convertView.setTag(bh);
       } else {
           bh= (BannerViewHolder) convertView.getTag();
       }
       bh.viewPager.setAdapter(new BannerAdapter(mainActivity,bannerlist));
       //清除之前handler发送的消息
       handler.removeCallbacksAndMessages(null);
       //发送请求
       handler.sendEmptyMessageDelayed(0,2000);
      } else {//news
          ListViewHolder lh = new ListViewHolder();
          if (convertView == null) {
              convertView=View.inflate(mainActivity,R.layout.lv_item,null);
              lh.title = convertView.findViewById(R.id.title);
              lh.summary = convertView.findViewById(R.id.summary);
              lh.icon = convertView.findViewById(R.id.icon);
              convertView.setTag(lh);
          } else {
              lh = (ListViewHolder) convertView.getTag();
          }

         News.ResultBean data= (News.ResultBean) getItem(position);
          lh.title.setText(data.getName());
          lh.summary.setText(data.getSummary());
          ImageLoader.getInstance().displayImage(data.getImageUrl(),lh.icon);
      }
        return convertView;
    }


  Handler handler=new Handler(){
      @Override
      public void handleMessage(Message msg) {
          super.handleMessage(msg);
          switch (msg.what){
              case 0:
                  int positon=bh.viewPager.getCurrentItem();
                  positon++;
                  bh.viewPager.setCurrentItem(positon);
                  handler.sendEmptyMessageDelayed(0,2000);
                  break;
          }
      }
  };
    class BannerViewHolder {
        private ViewPager viewPager;
    }
    class ListViewHolder {
        private ImageView icon;
        private TextView title;
        private TextView summary;
    }
}

轮播图和新闻的Bean类省略

ImageLoader，加载图片

package com.xxx.zkb2;

import android.app.Application;
import android.graphics.Bitmap;

import com.nostra13.universalimageloader.core.DisplayImageOptions;
import com.nostra13.universalimageloader.core.ImageLoader;
import com.nostra13.universalimageloader.core.ImageLoaderConfiguration;

public class App extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        ImageLoader.getInstance().init(
                new ImageLoaderConfiguration.Builder(this)
                        .memoryCacheSizePercentage(10)
                        .diskCacheSize(50*1024*1024)
                        .defaultDisplayImageOptions(new DisplayImageOptions.Builder()
                                .cacheOnDisk(true)
                                .cacheInMemory(true)
                                .bitmapConfig(Bitmap.Config.ARGB_4444)
                        .build()
                        )
                        .build()
        );

    }
}

效果图如下
