實例代碼：

ArrayAdapter與ListView

package com.example.androidbasicdemo1;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ArrayAdapter;
import android.widget.ListView;

/**
 * ArrayList<類型>(context,int itemLayout, data)
 * context:上下文環境
 * itemLayout：自定義的每一項要顯示的Layout
 * data：要顯示的數據
 * 
 * 例子：
 * ArrayAdapter adapter = new ArrayAdapter(ArrayAdapterListViewActivity.this, android.R.layout.simple_list_item_1, data);
   android.R.layout.simple_list_item_1  --- 使用Android自帶的 每一項Listview顯示布局   -- 實際應用中常常自定義此item布局

public class ArrayAdapterListViewActivity extends Activity {

	private ListView listView;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_array_adapter_list_view);

		//從xml布局文件中獲得ListView對象
		listView = (ListView) findViewById(R.id.arrayadapterlistView1);
		
		//定義要顯示的數據
		String[] data = getResources().getStringArray(R.array.items_country);
		//定義適配器
		ArrayAdapter adapter = new ArrayAdapter(ArrayAdapterListViewActivity.this, android.R.layout.simple_list_item_1, data);
		
		//為ListView添加適配器
		listView.setAdapter(adapter);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		getMenuInflater().inflate(R.menu.array_adapter_list_view, menu);
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		int id = item.getItemId();

SimpleAdapter與ListView

package com.example.androidbasicdemo1;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.SimpleAdapter;

public class SimpleAdapterListViewActivity extends Activity {

	private List> data;
	
	private ListView listView;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_simple_adapter_list_view);
		
		
		listView = (ListView) findViewById(R.id.simpleadapterlistView1);
		
		SimpleAdapter adapter = new SimpleAdapter(SimpleAdapterListViewActivity.this, prepareData(), R.layout.slef_list_item1,new String[]{"姓名","性別"}, new int[]{R.id.selflistview1textView1,R.id.selflistview1textView2});
		
		listView.setAdapter(adapter);
	
		
		OnItemClickListener listener = new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView parent, View view, int position,
					long id) {
				setTitle(parent.getItemAtPosition(position).toString());
			}
		};
		
		listView.setOnItemClickListener(listener);

	}

	
	private List> prepareData(){
		data = new ArrayList>();
		Map item;
		item = new HashMap();
		item.put("姓名", "吳歡小盆友");
		item.put("性別", "女");
		data.add(item);
		item = new HashMap();
		item.put("姓名", "馮榮小朋友");
		item.put("性別", "女");
		data.add(item);
		item = new HashMap();
		item.put("姓名", "夏明");
		item.put("性別", "男");
		data.add(item);
		item = new HashMap();
		item.put("姓名", "小華");
		item.put("性別", "男");
		data.add(item);
		return data;
	}
	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		getMenuInflater().inflate(R.menu.simple_adapter_list_view, menu);
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		int id = item.getItemId();
		if (id == R.id.action_settings) {
			return true;
		}
		return super.onOptionsItemSelected(item);
	}
