SimpleAdapter

1、视图

1)主视图

 <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:layout_width="match_parent"
          android:layout_height="match_parent"
          android:id="@+id/lv"
         ></ListView>

 </RelativeLayout>

2)item视图

 <?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="match_parent"
     android:orientation="horizontal">"
     <ImageView
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:id="@+id/iv"
         />
     <TextView
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:id="@+id/tv"
         />

 </LinearLayout>

2、java代码

 package com.example.simpleadapter;

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

 import android.os.Bundle;
 import android.app.Activity;
 import android.view.Menu;
 import android.widget.ListView;
 import android.widget.SimpleAdapter;

 public class MainActivity extends Activity {

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

         ListView lv = (ListView)findViewById(R.id.lv);

         List<Map<String,Object>> data = new ArrayList<Map<String,Object>>();
         Map<String,Object> map1 = new HashMap<String,Object>();
         map1.put("nametext", "我是第一个功能");
         map1.put("iconid", R.drawable.btn_minus_disable_focused);

         Map<String,Object> map2 = new HashMap<String,Object>();
         map2.put("nametext", "我是第二个功能");
         map2.put("iconid", R.drawable.btn_minus_selected);

         Map<String,Object> map3 = new HashMap<String,Object>();
         map3.put("nametext", "我是第三个功能");
         map3.put("iconid", R.drawable.btn_radio_off_selected);

         Map<String,Object> map4 = new HashMap<String,Object>();
         map4.put("nametext", "我是第四个功能");
         map4.put("iconid", R.drawable.btn_radio_on_focused_holo_dark);

         Map<String,Object> map5 = new HashMap<String,Object>();
         map5.put("nametext", "我是第五个功能");
         map5.put("iconid", R.drawable.btn_radio_on_holo_dark);

         data.add(map1);
         data.add(map2);
         data.add(map3);
         data.add(map4);
         data.add(map5);

         lv.setAdapter(new SimpleAdapter(this, data, R.layout.list_item, new String[]{"nametext","iconid"}, new int[]{R.id.tv,R.id.iv}));
     }
