如何在ListView中嵌入ViewPager

最近2個月一直忙着做項目，一個是挑戰杯的互聯網專項賽事，最終獲得了國家三等獎。另一個是湖南省程序設計大賽應用開發類。終於忙完了。其中需要在listview中嵌入viewpager。於是網上學習了下。主要在第一個item中加入viewpager。

這裏貼出適配器的代碼

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;

簡短精煉，也是乾貨。
