    public String getTemperature ()
    {
        return "城市:"+"\n"+city+
                "\n今日："+weather_toady+
                "\n明天"+"\n"+weather_tomorror+
                "\n后天"+"\n"+weather_houtian+
                "\n大后天"+"\n"+weather_dahoutian+
                "\n"+
                "穿衣指数：\n"
        +cloth;
    }
    public String getWet()
    {
        return "风力指数\n"+
                wind_toady+"\n"+
                "感冒指数:\n"+
                cold+"\n"
                +"运动指数\n"+
                sport;
    }

    public String getLight()
    {
        return "紫外线指数\n"+
                light
                ;
    }

}

使用方法如下：

                String temperaturetext= weatherUtil.getTemperature();
                String temperaturetext2= weatherUtil.getWet();
                String temperaturetext3= weatherUtil.getLight();
          

用getTemperature ,getwet等方法即可获得当天天气等各项数据
