Android/Kotlin:错误:“期望顶级声明"任务:app:buildInfoGeneratorDebug“ [英] Android/Kotlin: Error: "Expecting a top level declaration > Task :app:buildInfoGeneratorDebug"

问题描述

我尝试编写一个类来管理SQLite数据库，但出现错误消息期待顶级声明> Task:app:buildInfoGeneratorDebug".

I try to write a class to manage a SQLite DB, but I have the error message "Expecting a top level declaration > Task :app:buildInfoGeneratorDebug".

   package com.xexxxwxxxxs.GMP

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

    class DBHandler(context: Context, name: String?, factory: SQLiteDatabase.CursorFactory?, version: Int) : SQLiteOpenHelper(context, DATABASE_NAME, factory, DATABASE_VERSION)
    {
        override fun onCreate(db: SQLiteDatabase)
        {

        }

        override fun onUpgrade(db: SQLiteDatabase, oldVersion: Int, newVersion: Int)
        {

        }

        companion object
        {
            private val DATABASE_VERSION = 1
            private val DATABASE_NAME = "GMP.db"
        }
    } 

你有什么主意吗?

预先感谢

推荐答案

我只是删除最后一个花括号，然后再写一次.它正在工作:)

I just delete last curly brace and write it again. It's working :)
