对应的迁移代码：
database.execsql("DROP TABLE IF EXISTS Vehicle");
database.execsql("CREATE TABLE IF NOT EXISTS Vehicle(" +
"id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL," +
"vehicleName TEXT UNIQUE NOT NULL," +
"distanceUnit TEXT NOT NULL CHECK(distanceUnit = \"KM\" or distanceUnit = \"MILES\")," +
"currencyUnit TEXT NOT NULL," +
"mainFuelTank TEXT NOT NULL," +
"secondFuelTank TEXT," +
"vehiclePic TEXT," +
"modelName TEXT," +
"licensePlate TEXT," +
"vinNumber TEXT," +
"note TEXT," +
"isActive INTEGER NOT NULL DEFAULT 1 CHECK(isActive IN (0,1))," +
"customVehicleProps TEXT," +
"buildYear INTEGER," +
"ownerId INTEGER NOT NULL," +
"brandId INTEGER NOT NULL," +
"vehicleType TEXT NOT NULL CHECK(vehicleType = \"MOTORCYCLE\" or vehicleType = \"CAR\" or vehicleType = \"TRUCK\" or vehicleType = \"BUS\")," +
"FOREIGN KEY(\"ownerId\") REFERENCES \"Driver\"(\"id\") ON DELETE SET DEFAULT,"+
"FOREIGN KEY(\"brandId\") REFERENCES \"Brand\"(\"id\") ON DELETE SET DEFAULT)");
尽你所能，我有 2-3 个检查约束不允许虚拟值。 但是如果我尝试添加一个具有正确属性的对象。 例如
Vehicle{id=0,vehicleType=CAR,vehicleName='Audi',distanceUnit=KM,currencyUnit=NAD,mainFuelTank=FuelTank{fuelType=LIQUIDS,maxFuelAmount=50.0,volumeUnit=LITER},secondFuelTank=null,vehiclePic='null',brandId=1,modelName='',buildYear=null,ownerId=1,licensePlate='',vinNumber='',note='',isActive=true,customVehicleProps={=}}
我收到一个 CONSTRAINT 错误，这对我没有任何意义，导致 distanceUnit、isActive、 VehicleType 是正确的约束，主键也是自动增量，所以我不应该担心。 问题是什么？ 我确保我拥有用于距离单位和车辆类型的 ENUMS 的每个转换器类。

我的转换器如下所示：
@TypeConverter
public static distanceUnit fromStringTodistanceUnit(String value) {
Type listType = new Typetoken<distanceUnit>() {}.getType();
return gson.fromJson(value,listType);
}
@TypeConverter
public static String fromdistanceUnitToString(distanceUnit dUnit) {
return dUnit.toString();
}
@TypeConverter
public static VehicleType fromStringToVehicleType(String value) {
Type listType = new Typetoken<VehicleType>() {}.getType();
return gson.fromJson(value,listType);
}
@TypeConverter
public static String fromVehicleTypetoString(VehicleType vt) {
return gson.toJson(vt);
}
