Question

How can I parse this json objects with Gson this url: http://apis.skplanetx.com/weather/forecast/3hours?appKey=4ce0462a-3884-30ab-ab13-93efb1bc171f&version=1&lon=127.925

Answer 1

Use the Json scheme for the Gson parsing and it will give you the class like

package com.ledge.bean;

import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

import java.util.List;

public class WeatherParsing {

    @SerializedName("alertYn")
    @Expose
    private String alertYn;
    @SerializedName("stormYn")
    @Expose
    private String stormYn;

    public String getAlertYn() {
        return alertYn;
    }

    public void setAlertYn(String alertYn) {
        this.alertYn = alertYn;
    }

    public String getStormYn() {
        return stormYn;
    }

    public void setStormYn(String stormYn) {
        this.stormYn = stormYn;
    }


    public class Example {

        @SerializedName("weather")
        @Expose
        private WeatherParsing weather;
        @SerializedName("common")
        @Expose
        private WeatherParsing common;
        @SerializedName("result")
        @Expose
        private Result result;

        public WeatherParsing getWeather() {
            return weather;
        }

        public void setWeather(WeatherParsing weather) {
            this.weather = weather;
        }

        public WeatherParsing getCommon() {
            return common;
        }

        public void setCommon(WeatherParsing common) {
            this.common = common;
        }

        public Result getResult() {
            return result;
        }

        public void setResult(Result result) {
            this.result = result;
        }

    }
