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

}
