    WebView webview;

            webview.setWebViewClient(new WebViewClient() {

                    System.out.println("onPageStarted url->"+url);

                    System.out.println("onPage finished url->"+url);

                    /*if (url.startsWith(Constants.OAUTH2PARAMS.getRederictUri())) {
                        webview.setVisibility(View.INVISIBLE);

                        if (!handled) {
                            new ProcessToken(url,oAuth2Helper).execute();
                        }

                        webview.setVisibility(View.VISIBLE);
                    }*/
                }

            });  

            webview.loadUrl(REQUEST);   

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

这里我附加了屏幕截图！[网页不可用]
