Android嵌套h5图片适配问题

      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;"
            + "}"
            + "})()");
}
