问题描述

我有一堆像这样的 onclicklisteners,但是这个只是出于某种原因不想工作,我敢肯定我错过了一些明显的大声笑。尝试做的所有按钮都是注销。

我知道此时不是 startActivity 不起作用,而是整个侦听器,因为我添加了当我点击注销按钮时未触发的 Toast 制作文本警报。

我还尝试了“binding = FragmentProfileBinding.inflate(layoutInflater)”和“binding!!.btnLogout.setOnClickListener”,但是当我点击注销时,onClickListener 仍然无法工作或激活生成文本警报。

但是,任何帮助将不胜感激。

这是我的 kotlin 片段代码:

package com.example.nonutsinmybasket.fragments

import android.content.Intent
import android.content.SharedPreferences
import android.view.LayoutInflater
import android.view.ViewGroup
import android.os.Bundle
import android.view.View
import android.widget.Toast
import androidx.fragment.app.Fragment
import com.example.nonutsinmybasket.R
import com.example.nonutsinmybasket.activity.Login
import com.example.nonutsinmybasket.databinding.FragmentProfileBinding
import com.google.firebase.auth.FirebaseAuth
import kotlinx.android.synthetic.main.fragment_profile.view.*

class Profile(var userId: String?, var sharedPrefs: SharedPreferences) : Fragment() {
    var binding: FragmentProfileBinding? = null
    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        super.onCreate(savedInstanceState)
        val view  = inflater.inflate(R.layout.fragment_profile, container, false)
        setupLogoutButton(view, sharedPrefs)
        return view
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        // find views by id
    }

    private fun setupLogoutButton(view: View, sharedPrefs: SharedPreferences) {
        view.btnLogout.setOnClickListener {
            Toast.makeText(activity,
                "Tap detected",
                Toast.LENGTH_LONG).show()
            sharedPrefs.edit().remove("Email").apply()
            sharedPrefs.edit().remove("UserId").apply()
            FirebaseAuth.getInstance().signOut()
            startActivity(Intent(context, Login::class.java))
            activity?.finish()
        }
    }
}

这是我关联的 XML:

</androidx.constraintlayout.widget.ConstraintLayout>

不确定这是否有帮助,但在编写 view.btnLogout 时,我必须导入“import kotlinx.android.synthetic.main.fragment_profile.view.*”,否则文本为红色。
