上面的空指针错误不适用于我的代码，必须是 facebook 活动中的某些内容。 这是我的片段中的代码：

class LoginFragment : BaseFragment() {
    lateinit var callbackManager : CallbackManager
    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        return inflater.inflate(R.layout.fragment_login_initial, container, false)
    }
    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        toolbarSetup()
        setHasOptionsMenu(true)
        setOnClickListeners()

        callbackManager = CallbackManager.Factory.create()

        login_facebook.setOnClickListener {
            login_real_facebook.performClick()
        }
        login_real_facebook.setReadPermissions("email", "public_profile")
        login_real_facebook.registerCallback(callbackManager, object :
            FacebookCallback<LoginResult> {
            override fun onSuccess(loginResult: LoginResult) {
                Log.d("fb", "facebook:onSuccess:$loginResult")
                handleFacebookAccessToken(loginResult.accessToken)
            }

            override fun onCancel() {
                Log.d("fb", "facebook:onCancel")
                // ...
            }

            override fun onError(error: FacebookException) {
                Log.d("fb", "facebook:onError", error)
                // ...
            }
        })
    }
    private fun handleFacebookAccessToken(token: AccessToken) {
        Log.d("fb", "handleFacebookAccessToken:$token")

        val credential = FacebookAuthProvider.getCredential(token.token)
        firebaseAuth.signInWithCredential(credential)
            .addOnCompleteListener(requireActivity()) { task ->
                if (task.isSuccessful) {
                    // Sign in success, update UI with the signed-in user's information
                    Log.d("fb", "signInWithCredential:success")
                    findNavController().navigateUp()

                } else {
                    // If sign in fails, display a message to the user.
                    Log.w("fb", "signInWithCredential:failure", task.exception)
                    Toast.makeText(
                        requireContext(), "Authentication failed.",
                        Toast.LENGTH_SHORT
                    ).show()

                }


            }
    }


    private fun setOnClickListeners() {
        login_create.setOnClickListener {
            findNavController().navigate(R.id.action_loginFragment_to_registerFragment)
        }
        login_swibbid.setOnClickListener {
            findNavController().navigate(R.id.action_loginFragment_to_loginSwibbidFragment)
        }
    }

    private fun toolbarSetup() {
        toolbarService.nothingVisible()
        myToolbar.navigationIcon = null

    }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        callbackManager.onActivityResult(requestCode, resultCode, data)
    }

}

我已经设置了哈希值，所以不能，这是我使用的依赖项：

implementation 'com.facebook.android:facebook-login:8.0.0'

我也试过使用旧的，但它没有区别仍然是相同的错误。

Answer 1

堆栈跟踪表示某些内容为null ，因此请检查 toobarService 是否不为null或您更改可见性的任何其他元素

Answer 2

这修复了它...

login_real_facebook.fragment = this

真的很烦人，根本没有迹象表明这是问题！！！
