Я искал StackOverflow, но не нашел ответа. Мне нужно имя и фамилия профиля из Facebook после входа в систему. Профиль всегда нулевой после входа в систему. Как решить эту проблему?
Вот мой код:
private CallbackManager callbackManager;
private TextView textView;
private AccessTokenTracker accessTokenTracker;
private ProfileTracker mProfileTracker;
private FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
mProfileTracker = new ProfileTracker() {
@Override
protected void onCurrentProfileChanged(Profile profile, Profile profile2) {
Log.v("facebook - profile", profile2.getFirstName());
mProfileTracker.stopTracking();
}
};
mProfileTracker.startTracking();
AccessToken accessToken = loginResult.getAccessToken();
Profile profile = Profile.getCurrentProfile();
displayMessage(profile);
register(profile);
}
@Override
public void onCancel() {
}
@Override
public void onError(FacebookException e) {
}
};
public FBLoginFragment() {
}
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
callbackManager = CallbackManager.Factory.create();
accessTokenTracker= new AccessTokenTracker() {
@Override
protected void onCurrentAccessTokenChanged(AccessToken oldToken, AccessToken newToken) {
}
};
mProfileTracker = new ProfileTracker() {
@Override
protected void onCurrentProfileChanged(Profile oldProfile, Profile newProfile) {
displayMessage(newProfile);
}
};
accessTokenTracker.startTracking();
mProfileTracker.startTracking();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_main, container, false);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button);
textView = (TextView) view.findViewById(R.id.textView);
loginButton.setReadPermissions(Arrays.asList("public_profile", "user_friends"));
loginButton.setFragment(this);
loginButton.registerCallback(callbackManager, callback);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (callbackManager.onActivityResult(requestCode, resultCode, data))
return;
}
private void displayMessage(Profile profile){
if(profile != null){
textView.setText(profile.getName());
}
}
private void register(Profile profile){
new Register().execute(profile.getFirstName(), profile.getLastName());
}
@Override
public void onStop() {
super.onStop();
accessTokenTracker.stopTracking();
mProfileTracker.stopTracking();
}
@Override
public void onResume() {
super.onResume();
Profile profile = Profile.getCurrentProfile();
displayMessage(profile);
}
}
