ViewBinding with Card“View 对话框未正确显示宽度

问：

我必须迁移到 Android 应用程序中的 ViewBinding，以符合最新的目标版本。我真的很难让使用 CardView 创建的对话框正确显示。

下面是我修改以使用 ViewBinding 后的脚本。

override fun addUserDialog() {
    Handler(Looper.getMainLooper()).post(Runnable {
        LoggerUtils.logMessage("PMN Calling MFA User Dialog")
        var dialog = Dialog(this)
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
        dialog.setContentView(bindingMFA.root)
        dialog.setCancelable(false)
        bindingMFA.mBtnCancel.setOnClickListener {
            dialog.dismiss()
        }
        bindingMFA.mBtnConfirm.setOnClickListener {
            mMFACode = bindingMFA.mSMSMFA.text.toString()
            mLoginViewPresenter.confirmLogin(mMFACode)

            dialog.dismiss()
        }

        dialog.show()
        })

}

这出现在文件“loginActivity.kt”中，我在其中设置了 onCreate 中的绑定：

private lateinit var binding: ActivityLoginBinding
private lateinit var bindingMFA: DialogMfaBinding

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    binding = ActivityLoginBinding.inflate(layoutInflater)
    val view = binding.root
    setContentView(view)
    bindingMFA = DialogMfaBinding.inflate(layoutInflater)

如果我将行改回它，则显示对话框绝对没问题。dialog.setContentView(R.layout.dialog_mfa)

这是dialog_mfa.xml文件：

如果有人能够指出我做错了什么，将不胜感激！
