Android应用中使用ListView实现数据列表显示

UsingListViewActivity.java源码：

package com.sinaapp.ssun.listview;</p> <p>import java.util.ArrayList;<br /> import java.util.HashMap;<br /> import java.util.List;</p> <p>import android.app.Activity;<br /> import android.os.Bundle;<br /> import android.widget.ListView;<br /> import android.widget.SimpleAdapter;</p> <p>public class UsingListViewActivity extends Activity {<br /> private List<Person> persons = new ArrayList<Person>();<br /> private ListView listView; </p> <p> @Override<br /> public void onCreate(Bundle savedInstanceState) {<br /> super.onCreate(savedInstanceState);<br /> setContentView(R.layout.main);<br /> listView = (ListView) this.findViewById(R.id.listView);</p> <p> for(int i=0; i<10; i++){<br /> Person p = new Person("SSUN-"+i,"12340-"+i,i*100);<br /> persons.add(p);<br /> }</p> <p> show();<br /> }</p> <p> private void show() {<br /> List<HashMap<String, Object>> data = new ArrayList<HashMap<String,Object>>();</p> <p> for(Person p : persons){<br /> HashMap<String, Object> hm = new HashMap<String, Object>();<br /> hm.put("name", p.getName());<br /> hm.put("phone", p.getPhone());<br /> hm.put("amount", p.getAmount());<br /> data.add(hm);<br /> }</p> <p> SimpleAdapter adapter = new SimpleAdapter(this,data,R.layout.item,<br /> new String[]{"name","phone","amount"},<br /> new int[]{R.id.name,R.id.phone,R.id.amount});<br /> listView.setAdapter(adapter);<br /> }<br /> }</p> <p>class Person{<br /> private String name;<br /> private String phone;<br /> private Integer amount;</p> <p> public Person(String name,String phone,Integer amount){<br /> this.name = name;<br /> this.phone = phone;<br /> this.amount = amount;<br /> }</p> <p> public String getName() {<br /> return name;<br /> }</p> <p> public void setName(String name) {<br /> this.name = name;<br /> }</p> <p> public String getPhone() {<br /> return phone;<br /> }</p> <p> public void setPhone(String phone) {<br /> this.phone = phone;<br /> }</p> <p> public Integer getAmount() {<br /> return amount;<br /> }</p> <p> public void setAmount(Integer amount) {<br /> this.amount = amount;<br /> }<br /> }</p> <p>
