Public Methods

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

Added in API level 18

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 Rect objects (left, top, right, and bottom).

Parameters
fraction The fraction from the starting to the ending values
startValue The start Rect
endValue The end Rect
Returns
  • A linear interpolation between the start and end values, given the fraction parameter.
