android - 从对象ArrayList获取项目

如何在OrganizationAccess中调用access_role？

这是类

用户

class User : Serializable {
    var id = ""
    var user_organization_accesses: ArrayList<OrganizationAccess>? = null
}

组织访问

class OrganizationAccess:Serializable {

    var access_role = ""
}

我尝试过的

  mUser = intent.getSerializableExtra(ARG_PARAM) as User // receive from previous activity
  longToast("Role is " + mUser.user_organization_accesses!!.xxx)

我应该为xxx写什么？

最佳答案

我已经解决了

 longToast("Role is " + mUser.user_organization_accesses!!.component1().access_role)
