(iv) Android Webview in depth (bottom)

This article mainly introduces, how to add WebView in the ListView, and implement the drop-down refresh, the effect

Nonsense not much to say, the direct process:

1.mainActivity Layout file:

<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 Main Interface Java code:

<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> ();p rivate 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 Adapter Item layout XML code:

<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:o rientation= "vertical" >    <webview        android:id= "@+id/wb_webview" android:layout_width= "Match_        Parent "        android:layout_height=" Match_parent "/></linearlayout></span>

4.adapter Adapter Java code:

<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 pm 10:53:37 */public class Myadapter ex Tends 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 = Vi Ew.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>

This can be implemented in the ListView embedded WebView and implement the effect of the drop-down refresh, the code is not much, and compare understood, not much to explain.
