解决webview内的iframe中的事件不可用的问题

最近做android的webview开发，使用iframe中嵌入了很多页面，嵌入的页面却不可用，最后发现是

 webview.setwebviewclient(new webviewclient() {
   @override
   public boolean shouldoverrideurlloading(webview view, string url) {
    return super.shouldoverrideurlloading(view, url);
   }

不要覆写

shouldoverrideurlloading

这个方法，覆写这个方法会拦截ifame中的事件。

补充知识：android 原生webview访问使用iframe网页问题（页面找不到了）

问题：

项目使用原生webview访问使用了iframe的网页出现的问题，列表页使用iframe跳转到淘宝客的地址，单独访问淘宝客地址是能够打开。但列表页跳转过去总是提示“页面找不到了”，尝试很多方法，最终发现是webview对第三方cookie支持的问题。

解决：

if (android.os.build.version.sdk_int >= build.version_codes.lollipop)
cookiemanager.getinstance().setacceptthirdpartycookies(mwebview, true);

完整配置：

  mwebview.setwebviewclient(new webviewclient() {
   @override
   public void onpagestarted(webview view, string url, bitmap favicon) {
    super.onpagestarted(view, url, favicon);
   }

   @override
   public void onreceivedsslerror(webview view, sslerrorhandler handler, sslerror error) {
    handler.proceed();
    super.onreceivedsslerror(view, handler, error);
   }

   @override
   public boolean shouldoverrideurlloading(webview view, string url) { return super.shouldoverrideurlloading(view, url);
   }

   @targetapi(build.version_codes.lollipop)
   @override
   public webresourceresponse shouldinterceptrequest(webview view, webresourcerequest request) {
    return super.shouldinterceptrequest(view, request);
   }

   @override
   public void onpagefinished(webview view, string url) {
    super.onpagefinished(view, url);
    if (null != title && null != view && textutils.isempty(mtitle))
     title.settext(view.gettitle());
   }
  });
  mwebview.setwebchromeclient(new webchromeclient() {
          @override
          public void onprogresschanged(webview webview, int i) {
           super.onprogresschanged(webview, i);
          }

          @override
          public boolean onjsconfirm(webview view, string url, string message, android.webkit.jsresult result) {
           return super.onjsconfirm(view, url, message, result);
          }

          @override
          public void onshowcustomview(view view, customviewcallback callback) {
           super.onshowcustomview(view, callback);
          }

          @override
          public void onhidecustomview() {
          }

          @override
          public boolean onshowfilechooser(webview webview, android.webkit.valuecallback<uri[]> filepathcallback, filechooserparams filechooserparams) {
           return super.onshowfilechooser(webview, filepathcallback, filechooserparams);
          }

          @override
          public boolean onjsalert(webview view, string url, string message, android.webkit.jsresult result) {
           return super.onjsalert(view, url, message, result);
          }

          @override
          public void onreceivedtitle(webview view, string title) {
           super.onreceivedtitle(view, title);
          }
         }
