Android 图文混排通过webview实现并实现点击图片

在一个开源项目看到是用的webview 实现的
1. 这是在asset中的一个模板html

<html>

    <head>

        <title>News Detail</title>

                <meta name="viewport" content="width=device-width, minimum-scale=0.5, initial-scale=1.2, maximum-scale=2.0, user-scalable=1" />

        <link rel="stylesheet" type="text/css" href="css.css" />  

    </head>

    <body>

        <div id="header">

            <h3>

                        #title#

                        </h3>

            <div class="date">#time#</div>

        </div>

        <div id="content">

                #content#

        </div>

    </body>

</html>

2.模板的css

body {

    font-family: Helvetica, "Microsoft Yahei", Verdana, Helvetica, SimSun,

        Arial, "Arial Unicode MS", MingLiu, PMingLiu, "MS Gothic", sans-serief;

    margin: ;

    padding:  8px;

    background-color: #efeff0;

    color: #;

    word-wrap: break-word;

}  

p {

    margin-top: ;

    margin-bottom: 5pt;

    line-height: .6em;

}  

#header {

    text-align: center;

    background: transparent url('webBgLine.png') repeat-x scroll center

        bottom;

    padding-top: 6pt;

    margin-bottom: 5pt;

    -webkit-background-size: 320px 2px;

}  

#header h3 {

    margin-bottom: 0px;

    margin-top: 5px;

    font-size: 16pt;

    padding:  5pt;

    color: #;

    line-height: .3em;

}  

.date {

    color: #8e8e8e;

    font-size: 12pt;

    padding: 8pt ;

}  

#content {

    font-size: 14pt;

    line-height: 1.8;

}  

img {

    max-width: 310px;

    height: auto;

}  

div.bimg {

    text-align: center;

    padding: ;

}  

.photo_title {

    font-weight: bold;

    font-size: 16pt;

    margin-top: 15px;

}  

.langs_cn {

    color: #;

}  

audio {

    width: %

}  

* {

    -webkit-touch-callout: none;

    /* prevent callout to copy image, etc when tap to hold */

    /*-webkit-text-size-adjust: none;*/

    /* prevent webkit from resizing text to fit */

    -webkit-tap-highlight-color: rgba(, , , 0.15);

    /* make transparent link selection, adjust last value opacity 0 to 1.0 */

    /*-webkit-user-select: none; /* prevent copy paste, to allow, change 'none' to 'text' */

}  

@media screen and (-webkit-device-pixel-ratio: ) {

    #header {

        background-image: transparent url('webBgLine@2x.png') repeat-x scroll

            center bottom;

        -webkit-background-size: 320px 1px;

    }

}

3.测试的一个html文件将来会在网络中获取

主要的代码：

package com.su.imagetextview;  

import java.io.IOException;

import java.io.InputStream;  

import android.app.Activity;

import android.content.res.AssetManager;

import android.os.Bundle;

import android.util.Log;

import android.view.GestureDetector.OnGestureListener;

import android.view.MotionEvent;

import android.view.View;

import android.view.View.OnLongClickListener;

import android.view.View.OnTouchListener;

import android.webkit.WebSettings;

import android.webkit.WebView;

import android.webkit.WebView.HitTestResult;

import android.widget.Toast;  

public class WebViewActitivy extends Activity {

    private String TAG = "WebViewActitivy";

    private WebView webView;  

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        setContentView(R.layout.webview);

        super.onCreate(savedInstanceState);

        webView = (WebView) findViewById(R.id.news_body_webview_content);

        webView.getSettings().setDefaultTextEncodingName("utf-8");// 避免中文乱码

        webView.addJavascriptInterface(this, "javatojs");

        webView.setScrollBarStyle();

        WebSettings webSetting = webView.getSettings();

        webSetting.setJavaScriptEnabled(true);

        webSetting.setNeedInitialFocus(false);

        webSetting.setSupportZoom(true);

        webSetting.setCacheMode(WebSettings.LOAD_DEFAULT

                | WebSettings.LOAD_CACHE_ELSE_NETWORK);  

        try {

            // 读取来自assets的信息 实际操作 _newsContent 来自网络

            String _newsContent = getStringFromAssets("test.html");

            // 这是本地的html模板

            String htmlContent = getStringFromAssets("NewsDetail.html");  

            // 替换文本

            String newsInfo = "发表时间:" + "" + " 查看:" + "";

            String newsTitle = "测试Html图文混排";

            String LOCAL_PATH = "file:///android_asset/";// 本地html

            // 替换信息加载到html模板中

            webView.loadDataWithBaseURL(

                    LOCAL_PATH,

                    htmlContent.replace("#title#", newsTitle)

                            .replace("#time#", newsInfo)

                            .replace("#content#", _newsContent), "text/html",

                    "utf-8", null);

            webView.setOnTouchListener(touchlistener);

            /**

             * 长按获取图片地址可以进行放大保存等操作

             */

            webView.setOnLongClickListener(new OnLongClickListener() {

                    }

                    return true;

        } catch (Exception e) {

        }
