Android WebView 图片宽度自适应屏幕
实现方法如下
WebSettings settings = mWebView.getSettings();
settings.setJavaScriptEnabled(true);//支持JS
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>";
mWebView.loadData(html+js,"text/html; charset=UTF-8", null);
注：js一定要跟在html内容后
