遇到这么长一段html文本，图片大小不一，调webView也没什么效果，可以试试Jsoup

方法封装好了

private String getNewContent(String htmltext){Document doc=Jsoup.parse(htmltext);Elements elements=doc.getElementsByTag("img");for (Element element : elements) {element.attr("width","100%").attr("height","auto");}Log.d("VACK", doc.toString());return doc.toString();}

接下来只要调用webView.loadDataWithBaseURL(null,getNewContent(htmltext2), "text/html", "utf-8", null);

就可以让图片大小和屏幕同宽，平且高度自动缩放，而且gif也是正常的缩放

如果觉得图片大小还不好看可以继续调这里

element.attr("width","100%").attr("height","auto");

改动前的效果，屏幕都不足显示图片的一半

而改动后，大小刚好

另外如果你导入的jsoup包在1.63以上可能会出现
