Android WebView显示图片适配屏幕宽度

 String js = "<script type=\"text/javascript\">"+
                    "var imgs = document.getElementsByTagName('img');" + // 找到img标签
                    "for(var i = 0; i<imgs.length; i++){" +  // 逐个改变
                    "imgs[i].style.width = '100%';" +  // 宽度改为100%
                    "imgs[i].style.height = 'auto';" +
                    "}" +
                    "</script>";

 webView.loadData((data.getProjectDescription()+js).replace("&amp;zoom=640w",""), "text/html;charset=utf-8", null);
