mapped data from json in kotlin shows wrong value-CodePudding

I need to show this data in my sample kotlin app.

I have created all appropriate models using moshi. Which can be found here.

But the values are showing wrong. Even non null values are showing as null.

Example json, value in 0 index:

      "main": {
        "temp": 25.78,
        "feels_like": 25.95,
        "temp_min": 23.35,
        "temp_max": 25.78,
        "pressure": 1014,
        "sea_level": 1014,
        "grnd_level": 1012,
        "humidity": 59,
        "temp_kf": 2.43
      },

The model responsible:

@Parcelize
@JsonClass(generateAdapter = true)
data class Main(

    @Json(name = "temp")
    val temp: Double?,
    @Json(name = "feels_like")
    val feelsLike: Double?,
    @Json(name = "temp_min")
    val tempMin: Double?,
    @Json(name = "temp_max")
    val tempMax: Double?,
    @Json(name = "pressure")
    val pressure: Double?,
    @Json(name = "sea_level")
    val seaLevel: Double?,
    @Json(name = "grnd_level")
    val grndLevel: Double?,
    @Json(name = "humidity")
    val humidity: Double?,
    @Json(name = "temp_kf")
    val tempKf: Double?,

) : Parcelable {

    fun getTempString(): String {
        return temp.toString().substringBefore(".")   "°"
    }

    fun getHumidityString(): String {
        return humidity.toString()   "°"
    }

    fun getTempMinString(): String {
        return tempMin.toString().substringBefore(".")   "°"
    }

    fun getTempMaxString(): String {
        return tempMax.toString().substringBefore(".")   "°"
    }
}

But when I print the main in 0 index shows:

Main(temp=298.26, feelsLike=null, tempMin=null, tempMax=null, pressure=1014.0, seaLevel=null, grndLevel=null, humidity=62.0, tempKf=null)

As a result the views are not working either.

CodePudding user response：

See discussion here, it might be that the following anotation @field:Json(name = "temp_min") instead of @Json(name = "temp_min"), and the same for the other members, could fix it. Alternatively, you can try to use a different version of Moshi. Also, see related discussion Moshi @Json annotation not working for com.github.kittinunf.fuel.moshi.moshiDeserializerOf?
