android webview修改header X-Requested-With

webview请求url的时候会在header里面增加了X-Requested-With，怎么修改这个值

HashMap headers = new HashMap();

headers.put("Referer", p.url);

headers.put("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.2.6) Gecko/20100625

Firefox/3.6.6 Greatwqs");

headers.put("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");

headers.put("Accept-Language","zh-cn,zh;q=0.5");

headers.put("Host","www.yourdomain.com");

headers.put("Accept-Charset","ISO-8859-1,utf-8;q=0.7,*;q=0.7");

headers.put("Referer", "http://www.yourdomian.com/xxxAction.html");

HttpRequestBase httpget = ......

httpget.setHeaders(headers);

给你一个思路：重写 shouldOverrideUrlLoading 方法，自己可以去构造请求，当然也能自定义header，然后通过请求结果，构造给出 response。
