所以我已经处理这个问题好几天了.我有一个用于将信息发送回API的数据类.在本例中，我有x个域.在这些字段中，有三个不同类型的列表字段.
数据类
data class ApiSurveySiteUpdateBody(
@SerializedName("UserId") val userId: Int,
@SerializedName("SStatusId") val sStatusId: Int,
@SerializedName("SSId") val sSId: Int,
@SerializedName("SPONum") val sPoNum: Int,
@SerializedName("WorkPerformanceTypeId") val workPerformTypeId: Int,
@SerializedName("SSAddressId") val sSAddressId: Int,
@SerializedName("WorktoPerformDate") val workToBePerformedDate: String,
@SerializedName("CableRun") val cableRun: String,
@SerializedName("Entrance") val entranceInfo: String,
@SerializedName("DoorLockHardware") val doorLockHardware: String,
@SerializedName("HandicapOperator") val handicapOperator: String,
@SerializedName("DeviceComplete") val completedPrimaryDeviceList: List<Int>,
@SerializedName("TemplateId") val templateId: Int,
@SerializedName("NewDeviceList") val newDeviceList: List<ApiNewDeviceList> = emptyList(),
@SerializedName("UpdateDeviceList") val updateDeviceList: List<ApiUpdateDeviceList> = emptyList(),
@SerializedName("RemoveDeviceList") val removedDeviceList: List<ApiRemovedDeviceList> = emptyList()
)
转换器功能
private fun getSomeRequestBody(
dbInfo: DbFormWithEList,
apiSurveySiteMedias: List<ApiSSMediaInfo>
)
: ApiSSUpdateBody {
val updateRequestApi = ApiSSUpdateBody(
userId = dbInfo.sSDbInfo.userId,

Log.d(TAG, "newDeviceListRequestBodyAPI $newDeviceListRequestBody")
newDeviceListRequestBody
}
else if (sDeviceCheckedS == CHECKED_NO){
apiDeviceListMapperUpdateSS.sendDeviceNotExistsInNewDeviceList(dbEquipmentInfo)
}
else {
apiDeviceListMapperUpdateSS.sendEmptyNewDeviceList()
}
},
updateDeviceList = (List(dbInfo.equipmentList.size) { i ->

deviceLocation = dbEquipmentInfo.locationInfo,
deviceTechnicianNotes = dbEquipmentInfo.deviceTechnicianNotes
)
Log.d(TAG, "updateDeviceListRequestBodyAPI $updateDeviceListRequestBody")
updateDeviceListRequestBody
} else Unit.apply { } //<- the issue is here
}) as List<ApiUpdateDeviceList>,
removedDeviceList = List(dbInfo.sSDbInfo.removedDeviceList.size) { i ->
val dbRemovedMediaItem = dbInfo.sSDbInfo.removedDeviceList[i]
Log.d(TAG, "RemovedListDB $dbRemovedMediaItem")
if (dbRemovedMediaItem.removedDeviceEquipmentId == null && dbRemovedMediaItem.removedMediaName.isNullOrEmpty()){
val removeDevice = apiDeviceListMapperUpdateSiteSurvey.removeDevice(dbRemovedMediaItem)
Log.d(TAG, "removeDevice $removeDevice")
removeDevice
}else{
val removeMediaForExistingDevice = apiDeviceListMapperUpdateSS.removeMediaForExistingDevice(dbRemovedMediaItem)
Log.d(TAG, "removeMediaForExistingDevice $removeMediaForExistingDevice")
removeMediaForExistingDevice
}
}
)
Log.d(TAG, "MainUpdateRequestAPI $updateRequestApi")
return updateRequestApi
}
其目标是突出显示Else语句，以向该updateDeviceList字段返回一个空的列表"[]".我try 了几种方法，但始终无法返回确切的空列表"[]".任何帮助都将不胜感激.谢谢.
