简单的android天气预报

package com.ctl;

public class InfoUnit {
private String cityname = "";
private String time = "";
private String temper = "";
private String weather = "";
private String wind = "";

public String getCityname() {
return cityname;
}

public void setCityname(String cityname) {
this.cityname = cityname;
}

public String getTime() {
return time;
}

public void setTime(String time) {
this.time = time;
}

public String getTemper() {
return temper;
}

public void setTemper(String temper) {
this.temper = temper;
}

public String getWeather() {
return weather;
}

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

public String getWind() {
return wind;
}

public void setWind(String wind) {
this.wind = wind;
}
}

主要通过webservice获取相关城市的json格式数据信息，再解析json
