how can i parse json weather response - json

Question

this is my response from weather map api
{
"message": "accurate",
"cod": "200",
"count": 3,
"list": [
{
"id": 2641549,
"name": "Newtonhill",
"coord": {
"lat": 57.0333,
"lon": -2.15
},
"main": {
"temp": 275.15,
"pressure": 1010,
"humidity": 93,
"temp_min": 275.15,
"temp_max": 275.15
},
"dt": 1521204600,
"wind": {
"speed": 9.3,
"deg": 120,
"gust": 18
},
"sys": {
"country": ""
},
"rain": null,
"snow": null,
"clouds": {
"all": 75
},
"weather": [
{
"id": 311,
"main": "Drizzle",
"description": "rain and drizzle",
"icon": "09d"
}
]
}
how can i get the description i did get the temperature using a retrofit by seriazable object but i could'nt get the weather description
i did that to get temperature and the country
class WeatherResponse {
#SerializedName("sys")
var sys: Sys? = null
#SerializedName("main")
var main: Main? = null
#SerializedName("weather")
var weather: Weather? = null
}
class Main {
#SerializedName("temp")
var temp: Float = 0.0f
}
and i my main class im using a callback
fun getCurrentData() {
val retrofit = Retrofit.Builder()
.baseUrl(BaseUrl)
.addConverterFactory(GsonConverterFactory.create())
.build()
val service = retrofit.create(WeatherService::class.java)
val call = service.getCurrentWeatherData(lat, lon, AppId)
call.enqueue(object : Callback<WeatherResponse> {
override fun onResponse(call: Call<WeatherResponse>, response: Response<WeatherResponse>) {
if (response.code() == 200) {
val weatherResponse = response.body()!!
var temp = (weatherResponse.main!!.temp - 273).toString().substring(0,3) + " ºC"
tmp.text=temp
}
}
override fun onFailure(call: Call<WeatherResponse>, t: Throwable) {
}
})
}

Here is POJO class for your JSON. It now can be parsed easily.
WeatherResponse.kt
data class WeatherResponse(
#SerializedName("cod")
val cod: String? = null,
#SerializedName("count")
val count: Int? = null,
#SerializedName("list")
val list: List<X?>? = null,
#SerializedName("message")
val message: String? = null
) {
data class X(
#SerializedName("clouds")
val clouds: Clouds? = null,
#SerializedName("coord")
val coord: Coord? = null,
#SerializedName("dt")
val dt: Int? = null,
#SerializedName("id")
val id: Int? = null,
#SerializedName("main")
val main: Main? = null,
#SerializedName("name")
val name: String? = null,
#SerializedName("rain")
val rain: Any? = null,
#SerializedName("snow")
val snow: Any? = null,
#SerializedName("sys")
val sys: Sys? = null,
#SerializedName("weather")
val weather: List<Weather?>? = null,
#SerializedName("wind")
val wind: Wind? = null
)
data class Clouds(
#SerializedName("all")
val all: Int?
)
data class Coord(
#SerializedName("lat")
val lat: Double? = null,
#SerializedName("lon")
val lon: Double? = null
)
data class Main(
#SerializedName("humidity")
val humidity: Int? = null,
#SerializedName("pressure")
val pressure: Int? = null,
#SerializedName("temp")
val temp: Double? = null,
#SerializedName("temp_max")
val tempMax: Double? = null,
#SerializedName("temp_min")
val tempMin: Double? = null
)
data class Sys(
#SerializedName("country")
val country: String?
)
data class Weather(
#SerializedName("description")
val description: String? = null,
#SerializedName("icon")
val icon: String? = null,
#SerializedName("id")
val id: Int? = null,
#SerializedName("main")
val main: String? = null
)
data class Wind(
#SerializedName("deg")
val deg: Int? = null,
#SerializedName("gust")
val gust: Int? = null,
#SerializedName("speed")
val speed: Double? = null
)
}
You can get Weather description by using
var description = weatherResponse.list?.get(0)?.weather?.get(0)?.description
