Android原生中获取当前应用中有多少WebView

Android原生中获取当前界面或者该应用中有多少WebView的方法，最简单的方式如下：

                ArrayList<IWebview> weblist = SDK.obtainAllIWebview();
                for (int i = 0; i < weblist.size(); i++) {
                    String whichUrl = weblist.get(i).getOriginalUrl();//目标URL./specialCrowdGridvisit/searchspecial.html?zdrylxCode=05
                    if (weblist.get(i).getOriginalUrl().contains(loadUrl)) {
                        Log.d("autoDebug", (weblist.get(i)).toString());
                        IWebview iWebview = weblist.get(i);
                        currentIwebView = iWebview;
                        //iWebview.evalJS("(getDataFromNatives("+result+"))();");
//                        iWebview.evalJS("(function(){alert('识别的数据为：" + result + "');" +
//                                "conditionsInput.value='" + result + "';})();");
                    }
                }
