网页完成加载后关闭 ProgressDialog

Question

我正在将 URL 加载到 WebView 中。这是一个登录页面。当用户通过身份验证时，他会看到一个页面。我此时停止加载并开始另一个活动。

当点击登录按钮时，用户被重定向到第一个 url。我此时开始一个进度对话框。在他到达经过身份验证的页面后，我想停止进度对话框并直接显示新活动。我不希望用户看到经过身份验证的页面。

现在，“进度”对话框在经过身份验证的页面处停止。用户看到它，然后向他展示下一个活动

关于如何实现这一点的任何帮助？

这是我的代码：-

myWebView.getSettings().setJavaScriptEnabled(true);

            myWebView.loadUrl(url);

            final ProgressDialog progressBar = ProgressDialog.show(Details1.this, "Loading..", "Please wait!");

            myWebView.setWebViewClient(new WebViewClient()
            {



                @Override
                public void onPageStarted(WebView view, String url, Bitmap favicon) 
                {
                    // TODO Auto-generated method stub
                    super.onPageStarted(view, url, favicon);
                    url= view.getUrl();
                    redirected= Uri.decode(url);

                        if(redirected!=null &&redirected.contains("Visited"))
                        {
                            myprogressDialog= new Utility.ProgressDialogFragment().newInstance();
                            myprogressDialog.show(getFragmentManager(), "Wait");
                        }

                }

                @Override
                public void onPageFinished(WebView view, String url) 
                {
                    // TODO Auto-generated method stub
                    super.onPageFinished(view, url);
                    url= view.getUrl();
                    redirected= Uri.decode(url);

                        if(progressBar!=null && progressBar.isShowing())
                        {
                            progressBar.dismiss();
                        }






                 if(redirected!=null && redirected.startsWith(endpointHost+"/Authorize/index/"+device))//&& myprogressDialog!=null && myprogressDialog.isVisible())
                    {



                             myWebView.stopLoading();

                        myprogressDialog.dismiss();


                        String authorizationContentString =  myurl;
                        authorizationContentString =authorizationContentString.replace("|", "%7C");


                        new AuthenticateDevice(Details1.this,  Url).execute(authorizationContentString);




                    }



                }


                @Override
                public boolean shouldOverrideUrlLoading(WebView view, String url)
                {
                    // TODO Auto-generated method stub
                    view.loadUrl(url);


                    return true;

                }


            });

        }
        private static class ProgressDialogFragment extends DialogFragment
        {
             public static ProgressDialogFragment newInstance()
                {
                    return new ProgressDialogFragment();
                }

                @Override

                }
