Rect and RectF in Android SDK

转载：http://stackoverflow.com/questions/4913643/rect-and-rectf-in-android-sdk

Using

Rect

you
define its edges using integers and using

RectF

they
are defined as floats.

Looking at them more carefully I have spotted a few differences actually. I will only list what one implementation has more compared to the other one.

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)

So apparently there are some differences.
