我使用Facebook Login的简单应用程序遇到了一些问题。我已经检查了官方教程和其他一些材料,但我仍然无法得到结果。问题是调用onActivityResult
方法,但不调用回调方法。对我来说一切都很好看,所以我想我必须要错过一些东西。这是我的片段代码:
public class MainActivityFragment extends Fragment {
private CallbackManager callbackManager;
public MainActivityFragment() {
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
callbackManager = CallbackManager.Factory.create();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_main, container, false);
final LoginButton loginButton = (LoginButton)view.findViewById(R.id.login_button);
loginButton.setReadPermissions("public_profile");
loginButton.setFragment(this);
loginButton.registerCallback(callbackManager, facebookCallback);
return view;
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(resultCode, requestCode, data);
}
private FacebookCallback<LoginResult> facebookCallback = new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
AccessToken accessToken = loginResult.getAccessToken();
Profile profile = Profile.getCurrentProfile();
if(profile != null) {
Log.d("TAG","Welcome: " + profile.getName());
} else {
Log.d("TAG","Null?");
}
}
@Override
public void onCancel() {
Log.d("TAG", "Cancel");
}
@Override
public void onError(FacebookException e) {
Log.d("TAG", "Error: " + e);
}
};
}
在我的主要活动中,我只有Android Studio生成的代码,并且在Manifest中我拥有Facebook SDK所需的一切。散列码和包名称看起来是正确的。
答案 0 :(得分:1)
这是你的问题:
callbackManager.onActivityResult(resultCode, requestCode, data);
应该是:
callbackManager.onActivityResult(requestCode, resultCode, data);
