public Integer evaluate (float fraction, Integer startValue, Integer endValue)

Added in API level 14

This function returns the result of linearly interpolating the start and end values, with fraction representing the proportion between the start and end values. The calculation is a simple parametric calculation: result = x0 + t * (v1 - v0), where x0 is startValue, x1 is endValue, and t is fraction.

Parameters
fraction float: The fraction from the starting to the ending values
startValue Integer: The start value; should be of type int or Integer
endValue Integer: The end value; should be of type int or Integer
Returns
Integer A linear interpolation between the start and end values, given the fraction parameter.
