本文主要介紹一下，如何在listview中加入webview，並且實現下拉重新整理，效果

廢話不多說，直接過程：

1.mainActivity布局檔案：

<span style="font-size:14px;"><RelativeLayout 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=".MainActivity" >    <com.happy.demo.xlistview.XListView        android:id="@+id/xlv_list"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:background="#f5f5f5"        android:divider="#00000000"        android:footerDividersEnabled="false"        android:headerDividersEnabled="false"        android:listSelector="#00000000" >    </com.happy.demo.xlistview.XListView></RelativeLayout></span>

2.mainActivity主介面java代碼：

<span style="font-size:14px;">package com.happy.demo;import java.util.ArrayList;import java.util.List;import android.app.Activity;import android.os.Bundle;import android.os.Handler;import com.happy.demo.adapter.MyAdapter;import com.happy.demo.xlistview.XListView;import com.happy.demo.xlistview.XListView.IXListViewListener;public class MainActivity extends Activity implements IXListViewListener {private XListView xlv_list;private List<String> lists = new ArrayList<String>();private MyAdapter adapter;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);xlv_list = (XListView) this.findViewById(R.id.xlv_list);lists.add("http://www.qq.com");adapter = new MyAdapter(lists, MainActivity.this);xlv_list.setAdapter(adapter);xlv_list.setXListViewListener(this, 0);xlv_list.setPullLoadEnable(false);xlv_list.setRefreshTime();}@Overridepublic void onRefresh(int id) {new Handler().postDelayed(new Runnable() {@Overridepublic void run() {xlv_list.setRefreshTime();xlv_list.stopRefresh();}}, 3000);}@Overridepublic void onLoadMore(int id) {// TODO Auto-generated method stub}}</span>

3.adapter適配器item布局xml代碼：

<span style="font-size:14px;"><?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <WebView        android:id="@+id/wb_webView"        android:layout_width="match_parent"        android:layout_height="match_parent" /></LinearLayout></span>

4.adapter適配器java代碼：

<span style="font-size:14px;">package com.happy.demo.adapter;import java.util.List;import com.happy.demo.R;import android.content.Context;import android.view.View;import android.view.ViewGroup;import android.webkit.WebView;import android.widget.BaseAdapter;/** * @author zhonglq * @version V1.0 * @Date 2014-10-25 下午10:53:37 */public class MyAdapter extends BaseAdapter {private List<String> lists;private Context context;public MyAdapter(List<String> lists, Context context) {this.lists = lists;this.context = context;}@Overridepublic int getCount() {return lists.size();}@Overridepublic Object getItem(int position) {return lists.get(position);}@Overridepublic long getItemId(int position) {return position;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {if (convertView == null) {convertView = View.inflate(context, R.layout.list_item, null);}WebView wb_webView = (WebView) convertView.findViewById(R.id.wb_webView);setWebView(lists.get(position), wb_webView);return convertView;}private void setWebView(String url, WebView webView) {webView.loadUrl(url);}}</span>

這樣就可以實現在listview中嵌入webView並且實現下拉重新整理的效果了，代碼並不多，並且比較好懂，就不多作解釋了。
