ListView是开发过程中用得最多的列表组件。

package com.example.phonedemo;import com.example.phonedemo.util.Utils;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.ArrayAdapter;import android.widget.LinearLayout;import android.widget.ListView;import android.widget.Toast;public class ArrayAdapterDemo extends Activity {	private LinearLayout layout = null;	private ListView list = null;	private ArrayAdapter
    
      adapter = null;	private String[] arr = { "Beijing", "Shanghai", "Guangzhou", "Shenzhen",			"Guiyang", "Kunming", "Nanjing", "Hefei" };	@Override	protected void onCreate(Bundle savedInstanceState) {		// TODO Auto-generated method stub		super.onCreate(savedInstanceState);		this.layout = new LinearLayout(this);		this.layout.setOrientation(LinearLayout.VERTICAL);		this.list = new ListView(this);		this.adapter = new ArrayAdapter
     
      (this,				android.R.layout.simple_list_item_1, arr);		this.list.setAdapter(adapter);		this.list.setOnItemClickListener(new OnItemClickListener() {			@Override			public void onItemClick(AdapterView
       arg0, View arg1, int arg2,					long arg3) {				// TODO Auto-generated method stub				Toast.makeText(ArrayAdapterDemo.this,						ArrayAdapterDemo.this.arr[arg2], Toast.LENGTH_SHORT)						.show();			}		});		this.layout.addView(list, Utils.match);		super.addContentView(this.layout, Utils.match);	}}
