ArgbEvaluator

Kotlin |Java

class ArgbEvaluator : TypeEvaluator

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

Summary

Public functions
`Int`	`evaluate(fraction: Float, startValue: Int, 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.
`java-static ArgbEvaluator`	`getInstance()` Returns an instance of `ArgbEvaluator` that may be used in `setEvaluator`.

Public functions

evaluate

fun evaluate(fraction: Float, startValue: Int, 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

Returns
`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

java-static fun getInstance(): ArgbEvaluator

Returns an instance of ArgbEvaluator that may be used in setEvaluator. The same instance may be used in multiple Animators because it holds no state.

Returns
`ArgbEvaluator`	An instance of `ArgbEvaluator`.
