Method Detail

evaluate

public java.lang.Object evaluate(float fraction,
                                 java.lang.Object startValue,
                                 java.lang.Object endValue)

This function returns the calculated in-between value for a color given integers that represent the start and end values in the four bytes of the 32-bit int. Each channel is separately linearly interpolated and the resulting calculated values are recombined into the return value.

Specified by:

evaluate in interface android.animation.TypeEvaluator

Parameters:

fraction - The fraction from the starting to the ending values

startValue - A 32-bit int value representing colors in the separate bytes of the parameter

endValue - A 32-bit int value representing colors in the separate bytes of the parameter

Returns:

A value that is calculated to be the linearly interpolated result, derived by separating the start and end values into separate color channels and interpolating each one separately, recombining the resulting values in the same way.
