package="com.itheima28.simpleadapterdemo"
android:versionCode="1"
android:versionName="1.0">

3 activity_main.xml的文件内容

< RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
< ListView
android:id="@+id/listview"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

< /RelativeLayout>

4 listview_item.xml的文件内容

< ?xml version="1.0"encoding="utf-8"?>
< LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"

< /LinearLayout>

5 MainActivity的内容例如以下：

package com.itheima28.simpleadapterdemo;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.widget.ListView;
import android.widget.SimpleAdapter;

public class MainActivity extends ActionBarActivity {

@Override
protected void onCreate(BundlesavedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

ListView mListView = (ListView)findViewById(R.id.listview);

List< Map< String, Object> > data = https://www.songbingjia.com/android/new ArrayList< Map< String,Object> > ();

Map< String, Object> map = newHashMap< String,Object> ();
map.put("name", "张三1");
map.put("icon", R.drawable.f007);
data.add(map);

map = new HashMap< String,Object> ();
map.put("name", "张三2");
map.put("icon", R.drawable.f007);
data.add(map);

map = new HashMap< String,Object> ();
map.put("name", "张三3");
map.put("icon", R.drawable.f007);
data.add(map);

map = new HashMap< String,Object> ();
map.put("name", "张三4");
map.put("icon", R.drawable.f007);
data.add(map);

map = new HashMap< String,Object> ();
map.put("name", "张三5");
map.put("icon", R.drawable.f007);
data.add(map);

SimpleAdapter adapter = new SimpleAdapter(
this, //上下文
data, //listView绑定的数据
R.layout.listview_item, //listview的子条目的布局的id
new String[]{"name","icon"}, //data数据中的map集合里的key
new int[]{R.id.tv_name,R.id.iv_icon}); //resource中的id

mListView.setAdapter(adapter);
}
}
