在ListView中添加item为WebView

今天在做一个demo，是要把一个WebView当做ListView的item加入到ListView中去，查找了点资料，然后自己实现了一个，发现是可以做出来的，只是在ListView中加入的这个WebView的上下滚动有点问题，好像是WebView的滚动条和ListView的滚动条冲突了，导致上下滑动不能响应WebView的滚动条，暂时还不知道怎么去解决，只是把这个效果做出来了

首先是布局文件的代码：

main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >        <ListView         android:id="@+id/listView"        android:layout_width="match_parent"        android:layout_height="wrap_content"/></LinearLayout>

web_item.xml ，这个是含有webView的的那个item的布局

<?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/webView"        android:layout_width="match_parent"        android:layout_height="300dp" /></LinearLayout>

item.xml，这个是正常的item的布局

<?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" >            <TextView         android:id="@+id/tv"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:textSize="30sp"/>    </LinearLayout>

MainActivity.java

package com.slfly.webviewtest;import java.util.ArrayList;import java.util.List;import android.app.Activity;import android.os.Bundle;import android.webkit.WebView;import android.widget.ListView;public class MainActivity extends Activity {private WebView webView;private List<String> lists;private ListView listView;private MyAdapter mAdapter;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);initDatas();listView = (ListView) findViewById(R.id.listView);mAdapter = new MyAdapter(MainActivity.this,lists);listView.setAdapter(mAdapter);}public void initDatas(){lists = new ArrayList<String>();for(int i = 0 ; i< 20;i++){String s = "item----" + i;lists.add(s);}}}

MainActivity初始化了ListView等组件，然后把ListView要显示的数据源都添加到容器中，传给adapter

然后是MyAdapter的代码

package com.slfly.webviewtest;import java.util.List;import android.content.Context;import android.view.KeyEvent;import android.view.LayoutInflater;import android.view.View;import android.view.View.OnKeyListener;import android.view.ViewGroup;import android.webkit.WebView;import android.webkit.WebViewClient;import android.widget.BaseAdapter;import android.widget.TextView;public class MyAdapter extends BaseAdapter {private Context context;private List<String> lists;public MyAdapter(Context context, List<String> lists) {this.context = context;this.lists = lists;}@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) {convertView = bindView(position, convertView, parent);return convertView;}public View bindView(int position, View convertView, ViewGroup parent) {int itemType = getItemViewType(position);switch (itemType) {case 0:convertView = convertViewToWeb(convertView, parent);break;case 1:convertView = convertViewToItem(position, convertView, parent);break;}return convertView;}public View convertViewToWeb(View convertView, ViewGroup parent) {final WebHolder webHolder;if (convertView == null) {convertView = LayoutInflater.from(context).inflate(R.layout.web_item, null);webHolder = new WebHolder();webHolder.webView = (WebView) convertView.findViewById(R.id.webView);convertView.setTag(webHolder);} else {webHolder = (WebHolder) convertView.getTag();}webHolder.webView.getSettings().setJavaScriptEnabled(true);webHolder.webView.requestFocus();webHolder.webView.loadUrl("http://sina.cn/?from=www&ref=http%3A%2F%2Fwww.sina.com%2F");/** 使webview自己处理打开网页事件，不调用系统浏览器打开*/webHolder.webView.setWebViewClient(new WebViewClient() {@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {view.loadUrl(url);return true;}});/**使webview能够响应back按键，点击back按键回退网页，不会退出整个Activity*/webHolder.webView.setOnKeyListener(new OnKeyListener() {@Overridepublic boolean onKey(View view, int keyCode, KeyEvent event) {if(keyCode == KeyEvent.KEYCODE_BACK && webHolder.webView.canGoBack()){webHolder.webView.goBack();return true;}return false;}});return convertView;}public View convertViewToItem(int position, View convertView,ViewGroup parent) {ViewHolder holder = null;if (convertView == null|| !(convertView.getTag() instanceof ViewHolder)) {convertView = LayoutInflater.from(context).inflate(R.layout.item,null);holder = new ViewHolder();holder.tv = (TextView) convertView.findViewById(R.id.tv);convertView.setTag(holder);} else if (convertView.getTag() instanceof ViewHolder) {holder = (ViewHolder) convertView.getTag();}convertView.setTag(holder);holder.tv.setText(lists.get(position) + "");return convertView;}@Overridepublic int getItemViewType(int position) {if (position == 0) {return 0;} else {return 1;}}@Overridepublic int getViewTypeCount() {return 2;}public class ViewHolder {public TextView tv;}public class WebHolder {public WebView webView;}}

上一下最后运行的效果图
