【问题描述】：
当我尝试启动我的应用程序时出现无法解决的问题。我正在使用 Room 数据库和数据绑定。 我发现问题源于我的数据库类，但似乎找不到问题的解决方案
@Database(entities = [FietsItem::class, Merk::class], version = 5, exportSchema = false)
abstract class FietsDatabase : RoomDatabase() {
abstract fun fietsDao(): FietsDao
abstract fun merkDao(): MerkDao
companion object{
@Volatile
private var databaseInstance: FietsDatabase? = null
fun getDatabaseInstance(mContext: Context): FietsDatabase =
databaseInstance
?: synchronized(this){
databaseInstance
?: buildDatabaseInstance(
mContext
).also{
databaseInstance = it
}
}
private fun buildDatabaseInstance(mContext: Context) =
Room.databaseBuilder(mContext, FietsDatabase::class.java,
DB_NAME
)
.fallbackToDestructiveMigration()
.build()
}
}
const val DB_NAME = "FietsVerkoop.db"
当我评论这些行时，它起作用了：
abstract fun fietsDao(): FietsDao
abstract fun merkDao(): MerkDao
我的道课：
@Dao
interface FietsDao {
@Insert(onConflict = OnConflictStrategy.REPLACE)
fun insertFietsItem(data: FietsItem)
/*@Query("SELECT * FROM fietsen")
fun getAllRecords(): MutableLiveData<List<FietsItem>>*/
@Query("SELECT * FROM fietsen")
fun getAllRecords(): ArrayList<FietsItem>
@Delete
fun deleteFietsItem(fiets: FietsItem)
@Update
fun updateFietsItem(fiets: FietsItem)
}
@Dao
interface MerkDao {
@Insert(onConflict = OnConflictStrategy.REPLACE)
fun insertMerk(data: Merk)
/*@Query("SELECT * FROM ${Merk.TABLE_NAME}")
fun getAllRecords(): MutableLiveData<List<Merk>>*/
@Query("SELECT * FROM merken")
fun getAllRecords(): ArrayList<Merk>
@Delete
fun deleteMerk(merk: Merk)
@Update
fun updateMerk(merk: Merk)
}
我的实体类：
@Entity(tableName = Merk.TABLE_NAME)
data class Merk (
@PrimaryKey(autoGenerate = true)
@ColumnInfo(name = "merkid")
var MerkID:Int?=null,
@ColumnInfo(name = "merknaam")
var MerkNaam: String?=null
){
companion object{
const val TABLE_NAME="merken"
const val MERKID="merkid"
const val MERKNAAM="merknaam"
}
}
@Entity(tableName = FietsItem.TABLE_NAME)
data class FietsItem(
@PrimaryKey(autoGenerate = true)
@ColumnInfo(name = "fietsid")
var FietsID:Int?=null,
@ColumnInfo(name = "merk")
var Merk: Int?=null,
@ColumnInfo(name="type")
val Type: String?=null,
@ColumnInfo(name="prijs")
val Prijs: Double?=null,
@ColumnInfo(name="beschrijving")
val Beschrijving: String?=null,
@ColumnInfo(name="autonomie")
val Autonomie: Int ?= null
){
companion object{
const val TABLE_NAME="fietsen"
const val FIETSID="fietsid"
//const val MERK = "merk"
const val TYPE = "type"
const val PRIJS = "prijs"
const val BESCHRIJVING = "beschijving"
const val AUTONOMIE = "autonomie"
}
}
这是 --stacktrace 输出。

【问题讨论】：
-
尝试清理和构建项目，如果这不起作用，请尝试检查导致问题的确切日志。可能是由于 Dao 查询或函数返回类型将是原因，通常在 android studio 日志中，您将获得有关房间无法构建查询的更多信息。
-
清理和构建不起作用。整个事情的问题是我没有得到任何关于导致错误的原因以及错误来源的真实信息。
