1.编写my_listitem.xml配置文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:layout_width="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" 
    android:layout_height="wrap_content"
    android:id="@+id/myListItem" 
    android:paddingBottom="3dip"
    android:paddingLeft="10dip">
    <TextView android:layout_height="wrap_content"
        android:layout_width="fill_parent" 
        android:id="@+id/userId"
        android:textSize="20dp">
    </TextView>
    <TextView android:layout_height="wrap_content"
        android:layout_width="fill_parent" 
        android:textColor="#F00F11"
        android:id="@+id/userName">
        
    </TextView>
</LinearLayout>



2.编写DBActivity extends  ListActivity的java类

package com.yun.activity;
 
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
 
import com.example.yunsheng.R;
import com.yun.dao.UserDAO;
import com.yun.model.User;
 
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.SimpleAdapter;
 
public class DBActivity extends ListActivity {
 
  @Override
  public void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  // setContentView(R.layout.activity_dbactivity);
 
  UserDAO userDao = new UserDAO(this);
  List<User> list = new ArrayList<User>();
  list = userDao.getAllUser();
 
  ArrayList<HashMap<String, String>> mylist;
  mylist = new ArrayList<HashMap<String, String>>();
 
  for (int i = 0; i < list.size(); i++) {
    HashMap<String, String> map = new HashMap<String, String>();
    map.put("userId", String.valueOf(list.get(i).getUserId()));
    map.put("userName", list.get(i).getUserName());
    mylist.add(map);
  }
 
  SimpleAdapter adapter = new SimpleAdapter(this, mylist,
    R.layout.my_listitem, new String[] { "userId", "userName" },
    new int[] { R.id.userId, R.id.userName });
  setListAdapter(adapter);
 
  }
 
}


3.执行结果（项目中 的数据获取类来自上篇文章）


安卓学习：（7）安卓ListView的使用_android
