<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" android:layout_width="fill_parent"
	android:layout_height="fill_parent">

row.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

	<TextView android:id="@ id/text1" android:layout_width="fill_parent"
		android:layout_height="90px" />
</LinearLayout>

后端代码：

package com.test;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.BaseAdapter;

public class MainActivity extends Activity {

	String[] strs;

	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		strs = new String[] { "1111111", "22222222", "333333", "4444444",
				"55555555", "666666666", "77777777", "888888888", "9999999",
				"10000000" };
		android.widget.ListView listView = (android.widget.ListView) this
				.findViewById(R.id.list1);
		listView.setAdapter(new MyAdapter(this));

		// context.getSystemService(context.LAYOUT_INFLATER_SERVICE);

		listView
				.setOnItemClickListener(new android.widget.AdapterView.OnItemClickListener() {

					public void onItemClick(AdapterView<?> arg0, View arg1,
							int arg2, long arg3) {
						android.widget.ListView list = (android.widget.ListView) arg0;
						System.out.println(list.getAdapter().getItem(arg2));
						android.widget.TextView text = (android.widget.TextView) arg1;
						text.setText("click");
						System.out.println(arg3);
						System.out
								.println("***********************************************");
					}
				});
	}

	class MyAdapter extends BaseAdapter {

		Activity context;

		MyAdapter(Activity context) {
			this.context = context;
		}

		public int getCount() {
			return strs.length;
		}

		public Object getItem(int position) {
			return strs[position];
		}

		public long getItemId(int position) {
			return position   1;
		}

		public View getView(int position, View convertView, ViewGroup parent) {
			android.view.View view = convertView;
			VewWarpper wrapper = null;
			if (view == null) {
				view = (android.widget.LinearLayout) context
						.getLayoutInflater().inflate(R.layout.row, null);
				wrapper = new VewWarpper(view);
				view.setTag(wrapper);
			} else {
				wrapper = (VewWarpper) view.getTag();
			}
			android.widget.TextView textView = wrapper.getText();
			textView.setText(strs[position]);
			android.widget.ImageView imageView = wrapper.getImage();
			if ((position & 1) == 1) {
				imageView.setImageResource(android.R.drawable.ic_delete);
			} else {
				imageView.setImageResource(android.R.drawable.ic_menu_help);

			return view;
