android一个用SimpleAdapter适配的ListView

如题先给效果图：

 

主界面（MainActivity.java）：

package com.tody.listviewsimpledemo;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.Toast;

/**
 * 主界面
 * 
 * @author tody.yang
 * 
 */
public class MainActivity extends Activity {

	private ListView mListView;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		initView();
	}

	/**
	 * 初始化组件
	 */
	private void initView() {
		mListView = (ListView) findViewById(R.id.listView);

		String[] titleArr = { "我是第一项", "我是第二项", "我是第三项", "我是第四项", "我是第五项",
				"我是第六项", "我是第七项", "我是第八项", "我是第九项", "我是第十项", };

		int[] imageArr = { R.drawable.d0, R.drawable.d1, R.drawable.d2,
				R.drawable.d3, R.drawable.d4, R.drawable.d0, R.drawable.d1,
				R.drawable.d2, R.drawable.d3, R.drawable.d4 };

		List<HashMap<String, Object>> mList = new ArrayList<HashMap<String, Object>>();

		for (int i = 0; i < titleArr.length; i++) {
			HashMap<String, Object> mHashMap = new HashMap<String, Object>();
			mHashMap.put("title", titleArr[i]);
			mHashMap.put("imgUrl", imageArr[i]);
			mHashMap.put("content", "我就是内容");

			mList.add(mHashMap);
		}

		SimpleAdapter mSimpleAdapter = new SimpleAdapter(MainActivity.this,
				mList, R.layout.listview_item,
				// 对应HashMap的key属性
				new String[] { "title", "imgUrl", "content" },
				// 对应动态加载布局（listview_item.xml）的需要现实组件的ID
				new int[] { R.id.textView_title, R.id.imageView,
						R.id.textView_content });// 谷歌提供的适配器的一种

		mListView.setAdapter(mSimpleAdapter);// 列表设置适配器然后显示
		
		mListView.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
					long arg3) {
				// TODO Auto-generated method stub
				//这里虽然arg2和arg3都是能得到当前子项下标，但是推荐arg3，因为貌似有个方法arg2会得到空值
				Toast.makeText(MainActivity.this, "点击了第"+(arg3+1)+"项", Toast.LENGTH_SHORT).show();
			}
			
		});

	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.activity_main, menu);
		return true;
	}

}

主界面的布局文件（activity_main.xml）：

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" 
    >

     <ListView
        android:id="@+id/listView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
         >
        
    </ListView>

</LinearLayout>

动态加载的布局文件（listview_item.xml）：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal" >

        <TextView
            android:id="@+id/textView_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="我是标题" />

        <ImageView
            android:id="@+id/imageView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/d0" />
    </LinearLayout>

    <TextView
        android:id="@+id/textView_content"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="我是内容！！！" />

</LinearLayout>
