Android自定义listview及其点击事件监听

先看一下运行结果：

首先，在布局里面添加一个ListView.  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"    tools:context="${packageName}.${activityClass}" >    <ListView        android:id="@+id/list"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:background="#E4E0DE"        android:divider="#E4E0DE"        android:dividerHeight="2px"        android:paddingBottom="2px"        android:paddingTop="2px" >    </ListView></LinearLayout>

再新建一个list_item.xml文件

<pre name="code" class="html"><?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:orientation="horizontal"    android:background="#FFFFFF"    android:paddingTop="5dp"    android:paddingBottom="5dp"    android:paddingLeft="10dp"    android:layout_marginBottom="1px" >        <ImageView            android:id="@+id/img"            android:layout_width="40dp"            android:layout_height="40dp"            android:layout_gravity="center_vertical"            />        <TextView            android:id="@+id/text"            android:layout_width="0dp"            android:layout_height="fill_parent"            android:layout_weight="1"            android:gravity="center_vertical"            android:layout_marginLeft="10dp"            android:text="描述"            android:textSize="16sp"            android:textStyle="bold"            android:textColor="#22201F" />         <ImageView            android:id="@+id/go"            android:layout_width="wrap_content"            android:layout_height="40dp"            android:paddingLeft="10dp"            android:paddingRight="10dp"            android:layout_gravity="center_vertical"            android:src="@drawable/back"/></LinearLayout>

里面包含两个Imageview和一个Textview

再新建一个类，继承自BaseAdapter

<pre name="code" class="java">package com.effall.listviewdetail;import android.content.Context;import android.graphics.drawable.Drawable;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.ImageView;import android.widget.TextView;/**   *@Description:  *@Author: Effall *@Date: 2014年11月20日  */public class ListAdapter extends BaseAdapter {private Context context;private int [] imgList;private String[] stringList;private LayoutInflater layoutInflater;public ListAdapter(Context context,int [] imgList,String [] stringList){this.context=context;this.imgList=imgList;this.stringList=stringList;layoutInflater=LayoutInflater.from(context);}public int getCount() {return stringList.length;}public String getItem(int position) {return stringList[position];}public long getItemId(int position) {return position;}public View getView(int position, View convertView, ViewGroup parent) {ViewHolder holder=null;if(convertView==null){holder=new ViewHolder();convertView=layoutInflater.inflate(R.layout.list_item, null);holder.imageView=(ImageView)convertView.findViewById(R.id.img);holder.textView=(TextView)convertView.findViewById(R.id.text);convertView.setTag(holder);}else{holder=(ViewHolder)convertView.getTag();}holder.imageView.setBackgroundResource(imgList[position]);holder.textView.setText(stringList[position]);return convertView;}private class ViewHolder{public ImageView imageView;public TextView textView;}}

MainActivity.java

<pre name="code" class="java">package com.effall.listviewdetail;import android.app.Activity;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.view.Window;import android.widget.ListView;public class MainActivity extends Activity {private ListView listView;//列表private ListAdapter adapter;//列表适配器//列表中需要填充的数据private int[] imgList={R.drawable.img1,R.drawable.img2,R.drawable.img3};private String[] stringList={"数据库","数据结构","操作系统"};    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        requestWindowFeature(Window.FEATURE_NO_TITLE);//去掉标题栏        setContentView(R.layout.activity_main);                listView=(ListView)findViewById(R.id.list);        //实例化列表适配器        adapter=new ListAdapter(getApplicationContext(), imgList, stringList);        //为列表设置适配器        listView.setAdapter(adapter);    }}
