evaluate

public android.graphics.RectF evaluate(float fraction,
                                       android.graphics.RectF startValue,
                                       android.graphics.RectF endValue)

This function returns the result of linearly interpolating the start and end Rect values, with fraction representing the proportion between the start and end values. The calculation is a simple parametric calculation on each of the separate components in the RectF objects (left, top, right, and bottom).

指定者:

evaluate 在接口中 android.animation.TypeEvaluator<android.graphics.RectF>

参数:

fraction - The fraction from the starting to the ending values

startValue - The start RectF

endValue - The end RectF

返回:

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