Android中ListView最简单的用法

package com.chenliang.demo;

import java.util.ArrayList;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MyListView extends Activity {

	ListView mylv;
	public void onCreate(Bundle savedInstanceState){
		super.onCreate(savedInstanceState);
		mylv = new ListView(this);
		
		mylv.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_expandable_list_item_1,getData()));
		this.setContentView(mylv);
	}
	
	//  所要添加到的listview上的数据
	private ArrayList<String> getData() {
		// TODO Auto-generated method stub		
		ArrayList<String> alist = new ArrayList<String>();
		alist.add("=======001======");
		alist.add("=======002======");
		alist.add("=======003======");
		return alist;
	}
}

此段代码显示1列3行listview数据。其中调用了android系统自带布局ID：android.R.layout.simple_expandable_list_item_1
