如果只是单纯显示文字的话，ArrayAdapter是一个不错的选择。不用像之前的BaseAdapter那样写这么多东西。不过我还是习惯用BaseAdapter啊

package com.example.mylistview;

import java.util.Random;
import java.util.Vector;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.BaseAdapter;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.TextView;

public class MainActivity extends Activity {
	private ListView lv;
	private Random rd;
	private Vector arr;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		lv = (ListView) findViewById(R.id.lv);

		rd = new Random();
		arr = new Vector();
		
		for ( int i = 0 ; i < 50 ; i ++ ) {
			arr.add(String.valueOf(rd.nextInt(5000)));
		}
		
		lv.setAdapter(new ArrayAdapter<String>(this, R.layout.list_item, R.id.item_text,arr));

	}
}
