WebKit 上的JS直接使用Java Bean

引用：http://www.oschina.net/code/snippet_97818_4400

[代码] java bean代码

01 public class Bean{
02     private String title;
03  
04     public void setTitle(String title){
05         this.title = title;
06     }
07  
08     public String getTitle(){
09         return this.title;
10     }
11 }

[代码] android端

01 package com.xu81.tw4a;
02  
03 import java.util.List;
04  
05 import android.app.Activity;
06 import android.webkit.WebChromeClient;
07 import android.webkit.WebSettings;
08 import android.webkit.WebView;
09  
10 public class TiddlyWiki4Android extends Activity {
11  
12     private WebView mainWebView;
13  
14     /** Called when the activity is first created. */
15     @Override
16     public void onCreate(Bundle savedInstanceState) {
17         super.onCreate(savedInstanceState);
18         setContentView(R.layout.main);
19                  
20                 //webview对象
21         mainWebView = (WebView) findViewById(R.id.mainWebView);
22  
23         WebSettings setting = mainWebView.getSettings();
24         setting.setJavaScriptEnabled(true);//允许javascript
25         mainWebView.setWebChromeClient(new WebChromeClient());//初始化WebChromeClient对象
26                 Bean b = new Bean();
27                 b.setTitle("title");
28         mainWebView.addJavascriptInterface(b, "bean");//添加javascript对象
29         mainWebView.loadUrl("file:///android_asset/test.html");//加载本地html页面
30     }
31 }

[代码] javascript端调用方式

1 function getDefault(){
2     var bean = window.bean;
3     var title = bean.getTitle();
4         alert(title);
5 }
