1 实验目的。

输入要查询的城市名称，点击查询按钮后，依次出现七天的天气情况。

2 实验过程。

1、首先搞定天气预报数据来源的问题，提高天气预报服务的有很多网站，这些网站一般都会提供比较详细的 API 接口供应用程序调用。

3 代码部分。

Weather.java

package com.example.weather.moder;public class Weather {private String dayOfWeek;//星期几private String date;//日期private String temperature;//温度private String weather;//天气public Weather(){}public Weather(String dayOfWeek, String date, String temperature,String weather) {super();this.dayOfWeek = dayOfWeek;this.date = date;this.temperature = temperature;this.weather = weather;}public String getDayOfWeek() {return dayOfWeek;}public void setDayOfWeek(String dayOfWeek) {this.dayOfWeek = dayOfWeek;}public String getDate() {return date;}public void setDate(String date) {this.date = date;}public String getTemperature() {return temperature;}public void setTemperature(String temperature) {this.temperature = temperature;}public String getWeather() {return weather;}public void setWeather(String weather) {this.weather = weather;}@Overridepublic String toString() {return "Weather [dayOfWeek=" + dayOfWeek + ", date=" + date+ ", temperature=" + temperature + ", weather=" + weather + "]";}}

4 实验注意事项：在进行查询输入城市名时一定要先改编码格式列如

<span style="font-size:18px;">cityName = URLEncoder.encode("滨州", "utf-8");</span>
