I want to convert temperature value from unit to imperial in Retrofit in Android Studio

I want This Temperature Value that it give me

I have an issue in Retrofit. I want to convert Temperature value in Units To Imperial.

Mean I get data from API keys for Weather Application and when I run APP in Android it give me temperature values like this(285,200,etc). This is wrong because this temperature is not correctly. The now our Islamabad (Pakistan) city temperature is 15, and it give me 285, 200, etc, but JSON convertor give me a exact temperature of my city but Android Studio does not generate it.

I want the exact temperature of the city which API give me but android studio generate his own values which is not correct.

Solution

  • Can you try this once?

     JSONObject tempObject = arrWeatherList.getJSONObject(i).getJSONObject("temp");

 String temperature = changeTemp(tempObject.get("day").toString());

 private String changeTemp(String x) {
    Double celsius = Double.parseDouble(x) - 273.0;
    Integer i = celsius.intValue();
    return String.valueOf(i);
}
