listview + imageloder多条目加载

写三个xml文件第一个放入listview控件第二个写入所需控件，第三个也同样写入所需控件

1主Activty中

package com.example.wzqtemp;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.widget.ListView;import java.util.ArrayList;public class MainActivity extends AppCompatActivity {private   ListView lv;    private ArrayList<String> list=new ArrayList<String>();    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);      lv = (ListView) findViewById(R.id.lv);        lv.setAdapter(new Mydapter(MainActivity.this,list));     for (int i=0;i<10;i++){         list.add("haha"+i);     }    }}

2.适配器+imgloder文件

package com.example.wzqtemp;import android.content.Context;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;/** * author:Created by WangZhiQiang on 2017/9/6. */public class Mydapter extends BaseAdapter {    Context context;    ArrayList<String> list;    String string ="http://image.tianjimedia.com/uploadImages/2012/067/N80N0GUA36N0.jpg";    public Mydapter(Context context, ArrayList<String> list) {        this.context = context;        this.list = list;    }    private final int type1 = 0;    private final int type2 = 1;    @Override    public int getCount() {        return list.size();    }    @Override    public Object getItem(int i) {        return list.get(i);    }    @Override    public long getItemId(int i) {        return i;    }    @Override    public int getViewTypeCount() {        return 2;    }    @Override    public int getItemViewType(int position) {        if (position%2==0){            return type1;        }else  {            return  type2;        }    }    @Override    public View getView(int i, View view, ViewGroup viewGroup) {        int type = getItemViewType(i);        switch (type) {            case type1:                Holder1 holder1 = null;                if (view == null) {                    holder1 = new Holder1();                    view = view.inflate(context, R.layout.lv_ivm, null);                    holder1.textView = (TextView) view.findViewById(R.id.textView);                    holder1.textView2 = (TextView) view.findViewById(R.id.textView2);                    view.setTag(holder1);                } else {                    holder1 = (Holder1) view.getTag();                }                holder1.textView.setText(list.get(i));                holder1.textView2.setText(list.get(i));                break;            case type2:               Holder2 holder2=null;                if (view==null){                    holder2= new Holder2();                    view= view.inflate(context, R.layout.lv_ivm2, null);                    holder2.textView3=(TextView) view.findViewById(R.id.textView3);                    holder2.textView4=(TextView) view.findViewById(R.id.textView4);                   holder2.imageView=(ImageView) view.findViewById(R.id.imageView);                    view.setTag(holder2);                }else {                    holder2=(Holder2) view.getTag();                }                holder2.textView3.setText(list.get(i));                holder2.textView4.setText(list.get(i));                ImageLoader.getInstance().displayImage(string,holder2.imageView);                        break;                }                return view;        }        class Holder1 {          TextView textView;             TextView textView2;        }        class Holder2 {           TextView textView3;             TextView textView4;            ImageView imageView;        }}

3配置imgloder类

package com.wzq.moreitemlistviewdemo;


import android.app.Application;


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


/**
 * author:Created by WangZhiQiang on 2017-09-05.
 */


public class MApp extends Application {


    @Override
    public void onCreate() {
        super.onCreate();
        ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(this).build();




        ImageLoader.getInstance().init(config);




    }
}

4在清单文件中写入配置imgloder的类加上网络连接
