Getting no response for Retrofit GET request-CodePudding

I am beginner at Android development. Currently I am trying to implement simple API call with Open Weather API using Retrofit. Here is the code that doesn't go through:

var apiInterface:ApiInterface = getClient()!!.create(ApiInterface::class.java)
var call: Call<Example?>? = apiInterface.getWeatherData(tempName)

//after the call?.enqueue it shows me error down below

call?.enqueue(object : Callback<Example?> {
    override fun onResponse(call: Call<Example?>?, response: Response<Example?>) {
        try {
            Log.i("TAG", response.body()!!.main.toString())
            tempTemp = response.body()!!.main.temperature.toString()
            cityText.text = tempName
            currentTemperatureText.text = tempTemp
            descriptionText.text = response.body()!!.weather.description
            tempIcon = response.body()!!.weather.icon
            setIcon()

        } catch (e: Exception) {
            e.printStackTrace()
        }
    }

    override fun onFailure(call: Call<Example?>?, t: Throwable?) {}
})

I searched everywhere but couldn't find the solution. Thank you

CodePudding user response：

Create Empty class :

public class RetrofitResponse {

}

and use:

call?.enqueue(object : Callback<RetrofitResponse ?> {
override fun onResponse(call: Call<RetrofitResponse ?>?, response: Response<RetrofitResponse ?>) {
    try {
        Log.i("TAG", response.body()!!.main.toString())
        tempTemp = response.body()!!.main.temperature.toString()
        cityText.text = tempName
        currentTemperatureText.text = tempTemp
        descriptionText.text = response.body()!!.weather.description
        tempIcon = response.body()!!.weather.icon
        setIcon()

    } catch (e: Exception) {
        e.printStackTrace()
    }
}

override fun onFailure(call: Call<RetrofitResponse ?>?, t: Throwable?) {}

})

That problem from retrofit lib
