创建一个db的androiproject项目

同时创建一个MainActivity的Acitivity.java的类

新建com.gohighsoft.db包

MainActivity.java:

package com.gohighsoft.db;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import android.app.Activity;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.widget.AdapterView;

import android.widget.ListView;

import android.widget.SimpleAdapter;

public class MainActivity extends Activity {

private final static String TAG = "aa";

private PersonService personService;

private ListView listView;

// private PersonService personService;

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

personService = new PersonService(this);// 前十条数据

List< Person> persons = personService.getScrollData(0, 100);

listView = (ListView) findViewById(R.id.personList);

List< HashMap< String, String>> data = new ArrayList< HashMap< String, String>>();

HashMap< String, String> title = new HashMap< String, String>();

title.put("personid", "编号");

title.put("name", "姓名");

title.put("age", "年龄");

data.add(title);

for (Person person : persons) {

HashMap< String, String> map = new HashMap< String, String>();

map.put("personid", String.valueOf(person.getId()));

map.put("name", person.getName());

map.put("age", String.valueOf(person.getAge()));

data.add(map);

}
