listView.setOnItemClickListener(listener)   --- 将监听器注册到ListView中

实例代码：

ArrayAdapter与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<类型>(context,int itemLayout, data)
 * context:上下文环境
 * itemLayout：自定义的每一项要显示的Layout
 * data：要显示的数据
 * 
 * 例子：
 * ArrayAdapter<String> adapter = new ArrayAdapter<String>(ArrayAdapterListViewActivity.this, android.R.layout.simple_list_item_1, data);
   android.R.layout.simple_list_item_1  --- 使用Android自带的 每一项Listview显示布局   -- 实际应用中常常自定义此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);

		//从xml布局文件中获得ListView对象
		listView = (ListView) findViewById(R.id.arrayadapterlistView1);
		
		//定义要显示的数据
		String[] data = getResources().getStringArray(R.array.items_country);
		//定义适配器
		ArrayAdapter<String> adapter = new ArrayAdapter<String>(ArrayAdapterListViewActivity.this, android.R.layout.simple_list_item_1, data);
		
		//为ListView添加适配器
		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与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<Map<String, Object>> 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","性别"}, 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<Map<String, Object>> prepareData(){
		data = new ArrayList<Map<String, Object>>();
		Map<String, Object> item;
		item = new HashMap<String, Object>();
		item.put("姓名", "吴欢小盆友");
		item.put("性别", "女");
		data.add(item);
		item = new HashMap<String, Object>();
		item.put("姓名", "冯荣小朋友");
		item.put("性别", "女");
		data.add(item);
		item = new HashMap<String, Object>();
		item.put("姓名", "夏明");
		item.put("性别", "男");
		data.add(item);
		item = new HashMap<String, Object>();
		item.put("姓名", "小华");
		item.put("性别", "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);
	}
