现在我想使用网页浏览而不是浏览器登录(为什么因为有时候twitter没有重定向到我的应用程序).对于这个要求,我看到谷歌和SO的几乎所有建议,但我没有实现这一点.所以,请帮我用WebVIEw登录

解决方法 第1步：

在loginToTwitter()中这样做：

if (!isLoggedIn) {        final ConfigurationBuilder builder = new ConfigurationBuilder();        builder.setoAuthConsumerKey(consumerKey);        builder.setoAuthConsumerSecret(consumerSecret);        final Configuration configuration = builder.build();        final TwitterFactory factory = new TwitterFactory(configuration);        twitter = factory.getInstance();        try {            requestToken = twitter.getoAuthRequestToken(callbackUrl);            final Intent intent = new Intent(getActivity(),WebVIEwActivity.class);            intent.putExtra(WebVIEwActivity.EXTRA_URL,requestToken.getAuthenticationURL());            startActivityForResult(intent,WEBVIEW_REQUEST_CODE);        } catch (TwitterException e) {            e.printstacktrace();        }    }

第2步：

并通过在WebVIEwActivity中扩展WebVIEwClIEnt(如here)来创建webvIEwclIEnt

第3步：

并在主要活动中实现’onActivityResult’,例如：

if (requestCode == WEBVIEW_REQUEST_CODE) {        try {            String verifIEr = data.getExtras().getString(oAuthVerifIEr);            Accesstoken accesstoken = twitter.getoAuthAccesstoken(requestToken,verifIEr);            long userID = accesstoken.getUserID();            final User user = twitter.showUser(userID);            String username = user.getname();            saveTwitterInfo(accesstoken);            String ID = mSharedPreferences.getString(WSKeys.TwitterClass.PREF_USER_ID,"");            String name = mSharedPreferences.getString(WSKeys.TwitterClass.PREF_USER_name,"");            wscallSocialSignIn("",ID,accesstoken.toString(),name,image,"Twitter");        } catch (Exception exception) {        }    }
