Android嵌套h5图片适配问题

来源：互联网发布：java使用postmethod 编辑：程序博客网时间：2024/06/07 09:21

最近维护一个新闻相关APP,新闻详情是h5写的,后台新闻编辑的工具就是一个简单的编辑器,所有的图片操作居中之类的都需要客户自己操作,唉,不智能啊,苦了我们前端开发.

言归正传,问题就是客户上传的图片小,这边不处理的话就居右显示,特丑,,,,处理的方法如下所示,完美解决..

 webView.setWebViewClient(new WebViewClient() {                public boolean shouldOverrideUrlLoading(WebView view, String url) { //  重写此方法表明点击网页里面的链接还是在当前的webview里跳转，不跳到浏览器那边                    view.loadUrl(url);                    return true;                }                @Override                public void onPageFinished(WebView view, String url) {                    view.getSettings().setJavaScriptEnabled(true);                    super.onPageFinished(view, url);                    addImageClickListner(view);                    Tools.dismissWaitDialog();                }                @Override                public void onPageStarted(WebView view, String url, Bitmap favicon) {                    view.getSettings().setJavaScriptEnabled(true);                    super.onPageStarted(view, url, favicon);                }                @Override                public void onReceivedError(WebView view, int errorCode,                                            String description, String failingUrl) {                    Tools.dismissWaitDialog();                    super.onReceivedError(view, errorCode, description, failingUrl);                }                @Override                public WebResourceResponse shouldInterceptRequest(WebView view, String url) {                    WebResourceResponse response = super.shouldInterceptRequest(view, url);                    if (url != null && url.contains(INJECTION_TOKEN)) {                        String assetPath = url.substring(url.indexOf(INJECTION_TOKEN) + INJECTION_TOKEN.length(), url.length());                        try {                            response = new WebResourceResponse(                                    "application/javascript",                                    "UTF8",                                    webView.getContext().getAssets().open(assetPath)                            );                        } catch (IOException e) {                            e.printStackTrace(); // Failed to load asset file                        }                    }                    return response;                }            });        }    });}// 注入js函数监听private static void addImageClickListner(WebView webView) {    // 这段js函数的功能就是，遍历所有的img几点，并添加onclick函数，在还是执行的时候调用本地接口传递url过去    webView.loadUrl("javascript:(function(){"            + "var objs = document.getElementsByTagName(\"img\");"            + "for(var i=0;i<objs.length;i++)  "            + "{"            + "var img = objs[i]; "            + "winWidth = window.innerWidth;"            + "img.style.width = winWidth;"            + "}"            + "})()");}
