cometchat在kotlin中的实现

Question

我问了一个关于将cometchat集成到我的应用程序中的问题。我没有得到任何答复，但我会继续问安蒂，我解决了我的问题，因为我是非常新的科林。按照cometchat网站关于如何注册用户的指示，我在主要活动中添加了以下代码

val authKey = "AUTH_KEY" // Replace with your App Auth Key
    val user = User()
    user.getUid() = FirebaseAuth.getInstance().currentUser!!.uid // Replace with the UID for the user to be created
    user.getfullname() = full_name.toString() // Replace with the name of the user

    CometChat.createUser(user, authKey, object : CometChat.CallbackListener<com.cometchat.pro.models.User>() {
        override fun onSuccess(user: User) {
            Log.d("createUser", user.toString()
        }

        override fun onError(e: CometChatException) {
            Log.e("createUser", e.message)
        }
    })

不幸的是，user.getUid的下划线是红色的“变量预期”。我不知道那是什么意思。这是我的用户对象

package Model

class User {
private var stOforigin: String = ""
private  var fullname:String =""
private var bio:String =""
private var image:String =""
private var uid:String =""
private var gender:String =""
private var email:String =""

constructor()

constructor(fullname:String, bio:String, image:String, uid:String, gender:String , sos:String, 
email:String){
    this.fullname = fullname
    this.bio = bio
    this.image= image
    this.uid = uid
    this.stOforigin = sos
    this.gender =gender
    this.email = email
}

fun getfullname(s: String): String{
    return fullname
}
fun setfullname(fullname: String){
    this.fullname= fullname
}
fun getBio(): String{
    return bio
}
fun setBio(bio: String){
    this.bio= bio
}
fun getImage(): String{
    return image
}
fun setImage(image: String){
    this.image= image
}
fun getUid(uid: Any?): String{
    return this.uid
}
fun setUid(uid: String){
    this.uid= uid
}
fun getGender(): String{
    return gender
}
fun setGender(gender: String){
    this.gender= gender
}

fun getstOforigin(): String{
    return stOforigin
}
fun setstOforigin(stOforigin: String){
    this.stOforigin= stOforigin
}
fun getEmail(): String{
    return email
}
fun setEmail(email: String){
    this.email = email
}

}

不能为函数调用分配值。换句话说，无论foo() = 123做什么，foo()都是无效的语法。在您的情况下，与其调用getter样式函数(get...())，不如调用setter样式函数(set...())，将所需的值作为参数传递。

取代：

    user.getUid() = FirebaseAuth.getInstance().currentUser!!.uid // Replace with the UID for the user to be created
    user.getfullname() = full_name.toString() // Replace with the name of the user

通过以下方式：

    user.setUid(FirebaseAuth.getInstance().currentUser!!.uid) // Replace with the UID for the user to be created
    user.setfullname(full_name.toString()) // Replace with the name of the user

你可能想把这一切放在一边，先把注意力放在学习Kotlin上。如果有帮助的话，这是我关于科特林的一本免费书。。
