将 Enum 作为 Room 数据库 Library 的主键时出错
Error with making Enum as primary key at Room database Library
我正在使用枚举作为带有 TypeConvertor 的 Room 数据库的主键，它不会在 运行 时编译并抛出错误
这是我的转换器
class QuranIndexConverter {
@TypeConverter
fun toQuranIndex(index: String): QuranIndex {
return QuranIndex.valueOf(index)
}
@TypeConverter
fun toStringIndex(quranIndex: QuranIndex): String {
return quranIndex.name
}}
这里是道
@Dao
interface SuraDao {
@Query("SELECT * FROM " + Constants.TABLE_NAME)
fun getAll(): LiveData<List<Sura>>
@Insert
fun insertAll(suras: List<Sura>)
@Insert
fun insert(sura: Sura)
@Delete
fun deleteAll(suras: List<Sura>)
@Delete
fun delete(sura: Sura)}
这是模块
@Entity(tableName = Constants.TABLE_NAME)
data class Sura(
@PrimaryKey
val quranIndex: QuranIndex = QuranIndex.ABS,
@ColumnInfo(name = "sura_name")
val suraName: String = "Abasa",
@ColumnInfo(name = "download_url")
val downloadUrl: String = "www.google.com")
这里是房间数据库
@Database(
entities = arrayOf(Sura::class),
version = 1)
@TypeConverters(QuranIndexConverter::class)
abstract class Appdatabase : RoomDatabase() {
abstract fun suraDao(): SuraDao
}

我有这个错误，因为 kotlin 显然为具有默认参数值的单个 kotlin 构造函数生成多个 java 构造函数。工作代码我编辑数据 class 是这样的：
@Entity(tableName = Constants.TABLE_NAME)

@ColumnInfo(name = "sura_name")
val suraName: String ,
@ColumnInfo(name = "download_url")
