登录Facebook后重定向到新活动（Facebook SDK 3.5.2）

Question

我有两个用于Facebook登录的课程，它有效。 我可以按下Loginbutton，用我的用户名/密码写下来，它会登录我，但是我会带着我的徽标图片回到Main-class（s​​tartsite）等等

我想要做的是，当您按下登录按钮并登录时，您将重定向到新的活动

这是我可以看到的2个类，但是我在哪里进行重定向？ 在StackOverflow上阅读关于“onComplete”但我无法做到的，想想因为我使用SDK 3.5.2而不是2.0。那么如何在成功登录后重定向到新的活动。

我的主要活动：

public class SocialLoginActivity extends FragmentActivity {

private SocialLoginFragment socialLoginFragment;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (savedInstanceState == null) {
        // Add the fragment on initial activity setup
        socialLoginFragment = new SocialLoginFragment();
        getSupportFragmentManager().beginTransaction()
                .add(android.R.id.content, socialLoginFragment).commit();
    } else {
        // Or set the fragment from restored state info
        socialLoginFragment = (SocialLoginFragment) getSupportFragmentManager()
                .findFragmentById(android.R.id.content);
    }
}

}

这是FragmentClass：

public class SocialLoginFragment extends Fragment {

private static final String TAG = "SocialLoginFragment";
private UiLifecycleHelper uiHelper;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.activity_social_login, container,
            false);
    LoginButton authButton = (LoginButton) view
            .findViewById(R.id.authButton);
    authButton.setFragment(this);
    // authButton.setReadPermissions(Arrays.asList("name", "user_birthday",
    // "friends_birthday"));

    return view;
}

private void onSessionStateChange(Session session, SessionState state,
        Exception exception) {
    if (state.isOpened()) {
        Log.i(TAG, "Logged in...");
    } else if (state.isClosed()) {
        Log.i(TAG, "Logged out...");
    }
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    uiHelper = new UiLifecycleHelper(getActivity(), callback);
    uiHelper.onCreate(savedInstanceState);
}

private Session.StatusCallback callback = new Session.StatusCallback() {
    @Override
    public void call(Session session, SessionState state,
            Exception exception) {
        onSessionStateChange(session, state, exception);
    }
};

@Override
public void onResume() {
    super.onResume();

    Session session = Session.getActiveSession();
    if (session != null && (session.isOpened() || session.isClosed())) {
        onSessionStateChange(session, session.getState(), null);
    }
    uiHelper.onResume();
}

@Override
public void onPause() {
    super.onPause();
    uiHelper.onPause();
}

@Override
public void onDestroy() {
    super.onDestroy();
    uiHelper.onDestroy();
}

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    uiHelper.onSaveInstanceState(outState);
}

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

}

您看到的错误是因为Fragment不是Context对象。您需要获取父活动，例如：

Intent intent = new Intent(getActivity(), MainActivity.class);
