Public Methods

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

Since: API Level 11

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