내 앱에서 버튼처럼 간단하게 만들려고합니다. 필자는 이미 작동하는 공유 버튼을 만들었고 나는 포스트와 같은 것을 만들고 싶습니다. 이 코드를 작성하는 트링facebook SDK를 사용하여 Android 앱을 만드는 방법
메신저 :
{Response: responseCode: 200, graphObject: null, error: {HttpStatus: -1, errorCode: -1, errorType: null, errorMessage: java.lang.NullPointerException}, isFromCache:false}
일부는 내가 그것을 고칠 수있는 방법을 알고 :
public class MainFragment extends Fragment {
private UiLifecycleHelper uiHelper;
TextView tv1;
TextView tv2;
Button btn;
Button btnLike;
ProfilePictureView profilePictureView ;
String like="";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
uiHelper = new UiLifecycleHelper(getActivity(), callback);
uiHelper.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_main, container, false);
tv1=(TextView) view.findViewById(R.id.textView1);
tv2=(TextView) view.findViewById(R.id.textView2);
btn=(Button) view.findViewById(R.id.button1);
btnLike=(Button) view.findViewById(R.id.button2);
btn.setOnClickListener(shareListener);
btnLike.setOnClickListener(likeListener);
profilePictureView =(ProfilePictureView) view.findViewById(R.id.selection_profile_pic);
profilePictureView.setCropped(true);
LoginButton authButton = (LoginButton) view.findViewById(R.id.authButton);
authButton.setReadPermissions(Arrays.asList("user_likes", "user_status","public_profile"));
//authButton.setPublishPermissions(Arrays.asList("publish_action"));
authButton.setFragment(this);
return view;
}

아무것도하지만 내가 로그 캣에서이 오류가 .. happends 내 앱과 같은 버튼을 만드시겠습니까?
당신은 무엇을 의미합니까? 나는 "좋아"에 게시 ID를 넣어 ... 그 밖에 내가 뭘해야합니까? –
글쎄, 내 질문에, 당신이 제공 한 코드에 표시되지 않았기 때문에. – Tobi
죄송합니다 .... 왜 그 오류가 발생하는지 알 수 있습니까? –
