ArgbEvaluator

class ArgbEvaluator : TypeEvaluator<Int!>
kotlin.Any
   ↳ androidx.core.animation.ArgbEvaluator

This evaluator can be used to perform type interpolation between integer values that represent ARGB colors.

Summary

Public methods
Int
evaluate(fraction: Float, @NonNull startValue: Int, @NonNull endValue: 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.

static ArgbEvaluator

Returns an instance of ArgbEvaluator that may be used in ValueAnimator#setEvaluator(TypeEvaluator).

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 Animators because it holds no state.

Return
ArgbEvaluator An instance of ArgbEvaluator.
