[移动开发]kotlin中继承父属性使用构造方法

kotlin中继承父属性使用构造方法

1. 定义父类，给它两个属性：

abstract class AbstractResponseMessage {
    private var success = true
    private var reason: String? = null
    constructor() {}
    constructor(success: Boolean, reason: String?) {
        this.success = success
        this.reason = reason
    }
}

2. 子类继承该父类，其中 success和reason为父类属性：

class ChatResponseMessage : AbstractResponseMessage {
    var from: String = ""
    var content: String = ""
    constructor(from: String, content: String)
    constructor(success: Boolean, reason: String, from: String, content: String) : super(success, reason){
        this.from = from
        this.content = content
    }
}
