Android Rect和RectF的区别

1、精度不一样，Rect是使用int类型作为数值，RectF是使用float类型作为数值

2、两个类型提供的方法也不是完全一致

Rect：

equals(Object obj) (for some reason it as it's own implementation of equals)

exactCenterX()

exactCenterY()

flattenToString()

toShortString()

unflattenFromString(String str)

RectF：

round(Rect dst)

roundOut(Rect dst)

set(Rect src)
