直接调用即可，这个工具类会返回加载的网页中所有的链接，至于对链接怎么处理就是你们自己的事了， 亲测至今我所遇到的所有视频，它都可以捕获到其链接

调用

//初始化
this.parseWebUrlHelper=ParseWebUrlHelper.getInstance().init(this.mAct,"");
//解析网页中视频
parseWebUrlHelper.setOnParseListener(new ParseWebUrlHelper.OnParseWebUrlListener() {
                    @Override
                    public void onFindUrl(String url) {
                        Log.d("webUrl",url);
                        //*****处理代码
                    }
                    @Override
                    public void onError(String errorMsg) {
                    //****出错监听
