string.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="app_name">0_ListViewDemo</string>
    <string name="hello_world">Hello world!</string>
    <string name="menu_settings">Settings</string>
	<string name="name">姓名</string>
</resources>

main.xml

<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" >

    <TextView
		android:layout_width="fill_parent"
		android:layout_height="wrap_content"
		android:text="@string/name"
		/>
	<ListView
		android:layout_width="fill_parent"
		android:layout_height="wrap_content"
		android:id="@+id/listview"
		></ListView>

</RelativeLayout>

下面就是java代码了

package com.example.atestlistview;

import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.view.Menu;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class MainActivity extends Activity {

	private ListView listView;
	private String[] name = {"张三","李四","王五","刘六","张三","李四","王五","刘六"};
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		listView = (ListView) findViewById(R.id.listview);
		//创建一个ArrayAdapter
		listView.setAdapter(new ArrayAdapter<String>(this,
				android.R.layout.simple_list_item_1, name)); 
		//listView注册一个元素点击事件监听器
		listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
		@Override
		//当某个元素被点击时调用该方法
		public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
			Toast.makeText(MainActivity.this,name[arg2] ,
					Toast.LENGTH_LONG).show();
			}
		});
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.activity_main, menu);
		return true;
	}

}
