Public methods
evaluate
@NonNull fun evaluate(
fraction: Float,
@NonNull startValue: Int,
@NonNull endValue: Int
): Int
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.
Parameters | |
---|---|
fraction |
Float: The fraction from the starting to the ending values |
startValue |
Int: A 32-bit int value representing colors in the separate bytes of the parameter |
endValue |
Int: A 32-bit int value representing colors in the separate bytes of the parameter |
Return | |
---|---|
Int |
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. |
getInstance
@NonNull static fun getInstance(): ArgbEvaluator
Returns an instance of ArgbEvaluator
that may be used in ValueAnimator#setEvaluator(TypeEvaluator)
. The same instance may be used in multiple Animator
s because it holds no state.
Return | |
---|---|
ArgbEvaluator |
An instance of ArgbEvaluator . |
