适配器要重写两个方法

package com.example.duotiaomu;

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 com.nostra13.universalimageloader.core.ImageLoader;

import java.util.ArrayList;
import java.util.List;

public class Myadapter extends BaseAdapter {

List<Person.ResultDate> list;
Context context;
public void  addDats(List<Person.ResultDate> dates){
    if(dates !=null){
        list.addAll(dates);
        notifyDataSetChanged();
    }
}

public  void setDats(List<Person.ResultDate> dates){
    list = dates;
    notifyDataSetChanged();
}

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

public void setList(List<Person.ResultDate> list){
    this.list = list;
    notifyDataSetChanged();
}

(方法1)
@Override
public int getItemViewType(int position) {
if(position % 2 == 0){
return 0;
}else{
return 1;
}

}

(方法2)
@Override
public int getViewTypeCount() {
return 2; //这个是你要返回多少条目
}

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

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

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

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    if(getItemViewType(position) == 0){
        ViewHolde vh;
        if(convertView == null){
            convertView = LayoutInflater.from(context).inflate(R.layout.list_text1,null);
            vh = new ViewHolde(convertView);
        }else{
            vh = (ViewHolde) convertView.getTag();
        }
        Person.ResultDate data = (Person.ResultDate) getItem(position);
        vh.BindDate(data);


    }else{
        ViewHolde1 vh;
        if(convertView == null){
            convertView = LayoutInflater.from(context).inflate(R.layout.list_text2,null);
            vh = new ViewHolde1(convertView);
        }else{
            vh = (ViewHolde1) convertView.getTag();
        }
        Person.ResultDate data = (Person.ResultDate) getItem(position);
        vh.BindDate(data);
    }


    return convertView;
}
class ViewHolde{
    TextView t1;

    ImageView image;

    public ViewHolde(View view) {
        t1 = view.findViewById(R.id.t1);

        image = view.findViewById(R.id.image);
        view.setTag(this);
    }

    public void BindDate(Person.ResultDate data){
        t1.setText(data.getName());

        ImageLoader.getInstance().displayImage(data.getImageUrl(),image,ImageConfs.getpon());
    }
}
class ViewHolde1{
    TextView t1;

    ImageView image1;
    ImageView image2;

    public ViewHolde1(View view) {
        t1 = view.findViewById(R.id.t1);

        image1 = view.findViewById(R.id.image1);
        image2 = view.findViewById(R.id.image2);
        view.setTag(this);
    }

    public void BindDate(Person.ResultDate data){
        t1.setText(data.getName());
        ImageLoader.getInstance().displayImage(data.getImageUrl(),image1,ImageConfs.getpon());
        ImageLoader.getInstance().displayImage(data.getImageUrl(),image2,ImageConfs.getpon());
    }
}

}

//这是json解析数据写成一个类

package com.example.duotiaomu;

import java.util.List;

public class Person {
public List result;
public String message;
public int status;

public List<ResultDate> getResult() {
    return result;
}

public void setResult(List<ResultDate> result) {
    this.result = result;
}

public String getMessage() {
    return message;
}

public void setMessage(String message) {
    this.message = message;
}

public int getStatus() {
    return status;
}

public void setStatus(int status) {
    this.status = status;
}

public class ResultDate{
    public String name;
    public String summary;
    public String imageUrl;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getSummary() {
        return summary;
    }

    public void setSummary(String summary) {
        this.summary = summary;
    }

    public String getImageUrl() {
        return imageUrl;
    }

    public void setImageUrl(String imageUrl) {
        this.imageUrl = imageUrl;
    }
}

}

提取工具类
package com.example.duotiaomu;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class Util {
public String httpcon(String urls){
try {
URL url = new URL(urls);

        HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();

        httpURLConnection.setReadTimeout(5000);
        httpURLConnection.setConnectTimeout(5000);
        httpURLConnection.setRequestMethod("GET");

        int request = httpURLConnection.getResponseCode();
        if(request == 200){

            String str = String2(httpURLConnection.getInputStream());

            return  str;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;

}
private  String String2(InputStream inputStream) throws IOException {
    BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));

    StringBuilder stringBuilder = new StringBuilder();

    String text = null;
    while ((text = bufferedReader.readLine()) != null){
        stringBuilder.append(text);
    }
    bufferedReader.close();
    return  stringBuilder.toString();
}

}

剩下的 是布局文件

xmlns:app=“http://schemas.android.com/apk/res-auto

android:layout_width=“match_parent”
android:layout_height=“match_parent”

 <com.example.xlist.me.maxwin.view.XListView
     android:id="@+id/xlv"
     android:layout_width="match_parent"
     android:layout_height="match_parent"></com.example.xlist.me.maxwin.view.XListView>

</android.support.constraint.ConstraintLayout>

<?xml version="1.0" encoding="utf-8"?>

<TextView
    android:id="@+id/t1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="30dp"
    android:text="你好"
    />

<ImageView
    android:id="@+id/image"

    android:src="@drawable/ic_launcher_background"
    android:layout_marginLeft="40dp"
    />
<?xml version="1.0" encoding="utf-8"?>

<TextView
    android:id="@+id/t1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="发福"
    android:layout_marginTop="20dp"
    />

<ImageView

    android:layout_height="100dp"
    android:src="@drawable/ic_launcher_background"
    android:layout_marginTop="50dp"
    />

<ImageView
    android:id="@+id/image2"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:src="@drawable/ic_launcher_background"
