在项目开发中经常会将比较大的js、图片、css等放到app中,而html放服务器,这样在使用时流量较少,加载也比都放服务器上快,其实方法也比较多,网上搜了很久都没结果。

一种是获取服务器返回的html内容后,直接处理返回的html,在引用js、图片的地方替换其资源为本地的“file:///android_asset/”资源,这种方式我没试。

另一种就是直接使用WebViewClient实现

 1 webView.setWebViewClient(new WebViewClient(){ 2             @Override 3             public WebResourceResponse shouldInterceptRequest(WebView view, String url) { 4                 WebResourceResponse response = null; 5  6                     response = super.shouldInterceptRequest(view,url); 7                     if (url.contains("m.css")){ 8                         try { 9                             response = new WebResourceResponse("text/css","UTF-8",getAssets().open("css/m.css"));10                         } catch (IOException e) {11                             e.printStackTrace();12                         }13                     }14                 return  response;15             }16 });

注意最好是使用if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)来区分下版本执行的代码
