现在我想使用 WebView 而不是浏览器登录(为什么因为有时 twitter 不会重定向到我的应用程序)。对于这个要求，我在谷歌和 SO 中看到了几乎所有的建议，但我没能实现。所以，请帮助我使用 WebView 登录

Answer 1

链条 1:

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 创建 webviewclient，如 here

第 3 步:

并在您的主要 Activity 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) {

        }
    }
