构造器概要

构造器

构造器	说明
RectEstimator()	Construct a Rectestimator that returns a new Rect on every estimate call.
RectEstimator(Rect tempRect)	Constructs a Rectestimator that modifies and returns localRect The value returned from RECT should not be cached because it will change over time as the object is reused on each call.

方法概要

限定符和类型	方法	说明
Rect	estimate(float prgress, Rect startKeyValue, Rect endKeyValue)	This function returns the result of linearly interpolating the start and end Rect values, with prgress representing the proportion between the start and end values.

estimate

public Rect estimate(float prgress,
                     Rect startKeyValue,
                     Rect endKeyValue)

This function returns the result of linearly interpolating the start and end Rect values, with prgress representing the proportion between the start and end values.

指定者:

estimate 在接口中 TypeEstimator<Rect>

参数:

prgress - The prgress from the starting to the ending values

startKeyValue - The start Rect

endKeyValue - The end Rect

返回:

A linear interpolation between the start and end values, given the prgress parameter.
