最近2个月一直忙着做项目，一个是挑战杯的互联网专项赛事，最终获得了国家三等奖。另一个是湖南省程序设计大赛应用开发类。终于忙完了。其中需要在listview中嵌入viewpager。于是网上学习了下。主要在第一个item中加入viewpager。

这里贴出适配器的代码

package zero.com.nweq.adapter;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.ImageView;import android.widget.TextView;import java.util.List;import zero.com.nweq.R;import zero.com.nweq.beans.House;/** * 首页适配器 * Created by 邓慧 on 15/7/1. */public class HomeAdapter extends BaseAdapter {    private static final int TYPE_LISTVIEW = 0;    private static final int TYPE_VIEWPAGER = 1;    private static final int TYPE_COUNT = 2;    private Context context;    private List<House> list;    private View viewpager;    public HomeAdapter(Context c,List<House> list){        super();        this.context =c;        this.list =list;    }    /**     * 因为第一个不计算在内，估总数减1     * @return    */    @Override    public int getCount() {        return list.size()-1;    }    /**     * 判断位置返回不同对象     * @param position     * @return     */    @Override    public Object getItem(int position) {        if(position == 0){            return viewpager;        }else{            return list.get(position-1);        }    }    @Override    public long getItemId(int position) {        return position;    }    /**     * 主要方法     * @param position     * @param convertView     * @param parent     * @return     */    @Override    public View getView(int position, View convertView, ViewGroup parent) {        Holder holder = null;        House house = null;        switch (getItemViewType(position)) {            case TYPE_LISTVIEW:                house = list.get(position);                if (convertView == null) {                    holder = new Holder();                    convertView = LayoutInflater.from(context).inflate(R.layout.theme_list_view_item, null);                    holder.img = (ImageView) convertView.findViewById(R.id.theme_house_img);                    holder.name = (TextView) convertView.findViewById(R.id.theme_house_name);                    holder.place = (TextView) convertView.findViewById(R.id.theme_house_place);                    holder.time = (TextView) convertView.findViewById(R.id.theme_house_time);                    holder.theme = (TextView) convertView.findViewById(R.id.theme_house_theme);                    convertView.setTag(holder);                } else {                    holder = (Holder) convertView.getTag();                }                break;                        case TYPE_VIEWPAGER:                if (convertView == null) {                    convertView = viewpager;                }                return convertView;        }        //之所以要减一，是因为复用convertView时，要排除第一个位置        if (viewpager != null){            position--;        }        holder.img.setImageResource(house.getImageId());        holder.name.setText(house.getHouseName());        holder.place.setText(house.getHousePlace());        holder.time.setText(house.getTime());        holder.theme.setText(house.getTheme());        return convertView;    }    /**     * 提供方法从外部设置布局，这里可以设置不同的自定义Header布局，不仅仅是ViewPager     * @param view     */    public void setViewpager(View view){        viewpager = view;    }    /**     * 获取不同的布局类型     * @param position     * @return     */    @Override    public int getItemViewType(int position) {        if(viewpager != null){            return position > 0 ? TYPE_LISTVIEW : TYPE_VIEWPAGER;        }else{            return TYPE_LISTVIEW;        }    }    /**     * Item布局总样数     * @return     */    @Override    public int getViewTypeCount() {        return TYPE_COUNT;    }    public class Holder{        ImageView img;        TextView name;        TextView theme;        TextView place;        TextView time;    }}

简短精炼，也是干货。
