通过google接口在A
droid中实现天气预报效果
A
droid可以通过google实现获取指定经纬度位置或者某一个城市的天气信息。如果是根据经纬度查询天气信息，需要对精度为进行转换，例如lat值为31174165，需要过滤掉小数
点，变为31174165传到接口中，维度也一样处理，处理后传给httpwwwgooglecomigapiweather31174165121433841既可以获取数据。这里要注意一个问题，如果大家获取的经纬度序列很长，直接去掉小数点，有时候也无法获取天气信息，例如4047822483815252812497828006744385，去掉小数点后，传到参数位置，无法获取值，需要大家将经纬度按下面方式转换一下，只取小数点后6位就可以了。i
