我的片段代码是：

public class FragmentSample extends Fragment {
    private TwitterLoginButton loginButton;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
       View rootView=inflater.inflate(R.layout.fragment_sample,container,false);
        loginButton = (TwitterLoginButton)rootView. findViewById(R.id.twitter_login_button);

        return rootView;
    }

    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);
        Fabric.with(getActivity(), new Twitter(authConfig));

        loginButton.setCallback(new Callback<TwitterSession>() {
            @Override
            public void success(Result<TwitterSession> result) {
                // The TwitterSession is also available through:
                // Twitter.getInstance().core.getSessionManager().getActiveSession()
                TwitterSession session = result.data;
                // TODO: Remove toast and use the TwitterSession's userID
                // with your app's user model
                String msg = "@" + session.getUserName() + " logged in! (#" + session.getUserId() + ")";
                Toast.makeText(getActivity(), msg, Toast.LENGTH_LONG).show();
            }

            @Override
            public void failure(TwitterException exception) {
                Log.d("TwitterKit", "Login with Twitter failure", exception);
            }
        });
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        loginButton.onActivityResult(requestCode, resultCode, data);

    }
}

Answer 1

虽然很晚才是解决之道。

片段的onActivityResult不被直接调用。它调用您的活动的onActivityResult，它调用您的片段。因此，首先在您的活动上覆盖onActivityResult，如下所示，

fragment = getSupportFragmentManager().findFragmentByTag(title);
if (fragment != null) {
fragment.onActivityResult(requestCode, resultCode, data);
}

希望能奏效:)
