android - "too many arguments for public constructor string() defined "Kotlin问题

Question

我有点迷茫，创建一个数据库，用户必须在其中保存研究结果，他将从各种小部件(例如微调器或 RG)中选择数据。如何编码 Int 或 String 类型的变量对我来说不是问题，但在 Spinner 数字选择器和 RG 的情况下。有人可以纠正我吗？

主要 Activity

    var listaWynikow = ArrayList<FIrebaseVal>()

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_historia_pomiarow)
        setSupportActionBar(toolbar)

        //Wczytujemy baze danych
        LoadQuery("%")

        supportActionBar?.setDisplayHomeAsUpEnabled(true)
    }
    override fun onResume() {
        super.onResume()
        LoadQuery("%")
    }

    private fun LoadQuery(title:String){
        val dbManager = DbMenager(this)
        val projections = arrayOf("Id", "Stezenie", "Zegar","Data","Posilek","Stres","Samopoczucie","Hiperglikemia","Insulina")
        val cursor =
            dbManager.Query(projections, "Title like?", selectionArgs   , "Title")
        listaWynikow.clear()
        if (cursor.moveToFirst()) {
            do {
                ***val ID = cursor.getInt(cursor.getColumnIndex("Id"))      ---> HERE i have problem 
                val Stezenie = cursor.getInt(cursor.getColumnIndex("Stezenie")) ---> NumberPicker 
                val Zegar = cursor.getString(cursor.getColumnIndex("Zegar"))
                val Data =cursor.getString(cursor.getColumnIndex("Data"))
                val Posilek = cursor.getString(cursor.getColumnIndex("Posilek")) -----> RB
                val Stres = cursor.getString(cursor.getColumnIndex("Stres"))
                val Samopoczucie = cursor.getString(cursor.getColumnIndex("Samopoczucie"))   --->SPINNER
                val Hiperglikemia = cursor.getString(cursor.getColumnIndex("Hiperglikemia"))--->SPINNER
                val Insulina = cursor.getInt(cursor.getColumnIndex("Insulina"))       --->SPINNER
                **listaWynikow.add(Note(ID, Stezenie, Zegar,Data,Posilek,Stres,Samopoczucie,Hiperglikemia,Insulina))
            } while (cursor.moveToNext())*****
        }
    }

}

“---> Spinner、Numberpicker、RG”等不是代码

import android.content.Context
import android.database.Cursor
import android.database.sqlite.SQLiteDatabase
import android.database.sqlite.SQLiteOpenHelper

节点类

NODE CLASS 

    package com.example.apkadlapacjenta

import android.provider.MediaStore
import android.widget.NumberPicker
import android.widget.RadioGroup
import android.widget.Spinner

class FIrebaseVal(nodeID: Int, nodeNumberPicker:NumberPicker,nodezegar:String,nodedata:String,nodeposilek:RadioGroup,nodehiperglikemia:Spinner,nodestres:Spinner,nodesamopoczucie:Spinner,nodeinsulina:Int) {
    var nodeID: Int?= nodeID
    var nodeNumberPicker:NumberPicker?= nodeNumberPicker
    var nodezegar:String?=nodezegar
    var nodedata:String?=nodedata
    var nodeposilek:RadioGroup?=nodeposilek
    var nodehiperglikemia:Spinner?=nodehiperglikemia
    var nodestres:Spinner?=nodestres
    var nodesamopoczucie:Spinner?=nodesamopoczucie
    var nodeinsulina:Int?=nodeinsulina
}

剩下的代码我知道怎么做，即适配器和各种功能，如 SearchView等，在 Numberpicker、Spinner 和 RG 编码方面需要帮助，因为在行中:

listaWynikow.add(Note(ID, Stezenie, Zegar,Data,Posilek,Stres,Samopoczucie,Hiperglikemia,Insulina))
            } while (cursor.moveToNext())

我收到一个错误
“定义的公共(public)构造函数 string() 的参数太多”。

Answer 1

节点类的问题在这里你已经声明了总共 9 个参数:

class FIrebaseVal(nodeID: Int, nodeNumberPicker:NumberPicker,nodezegar:String,nodedata:String,nodeposilek:RadioGroup,nodehiperglikemia:Spinner,nodestres:Spinner,nodesamopoczucie:Spinner,nodeinsulina:Int)

但在这里您传递的 10 个参数请确认参数值。我无法理解变量名。

listaWynikow.add(Note(ID, Stezenie, Zegar,Data,Posilek,Stres,Samopoczucie,Hiperglikemia,Insulina))
