IntEvaluator

Kotlin |Java

public class IntEvaluator
extends Object implements TypeEvaluator<Integer>

java.lang.Object
↳	androidx.core.animation.IntEvaluator

This evaluator can be used to perform type interpolation between int values.

Summary

Public methods
`Integer`	`evaluate(float fraction, Integer startValue, Integer endValue)` This function returns the result of linearly interpolating the start and end values, with `fraction` representing the proportion between the start and end values.
`static IntEvaluator`	`getInstance()` Returns an instance of `IntEvaluator` that may be used in `ValueAnimator.setEvaluator(TypeEvaluator)`.

      evaluate(float fraction, Integer startValue, Integer endValue)

This function returns the result of linearly interpolating the start and end values, with fraction representing the proportion between the start and end values.

Public methods

evaluate

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

This function returns the result of linearly interpolating the start and end values, with fraction representing the proportion between the start and end values. The calculation is a simple parametric calculation: result = x0 + t * (x1 - x0), where x0 is startValue, x1 is endValue, and t is fraction.

Parameters
`fraction`	`float`: The fraction from the starting to the ending values
`startValue`	`Integer`: The start value; should be of type `int` or `Integer`
`endValue`	`Integer`: The end value; should be of type `int` or `Integer`

Returns
`Integer`	A linear interpolation between the start and end values, given the `fraction` parameter.

getInstance

public static IntEvaluator getInstance ()

Returns an instance of IntEvaluator that may be used in ValueAnimator.setEvaluator(TypeEvaluator). The same instance may be used in multiple Animators because it holds no state.

Returns
`IntEvaluator`	An instance of `IntEvaluator`.
