ArgbEvaluatorCompat

public class ArgbEvaluatorCompat
extends Object implements TypeEvaluator<Integer>

java.lang.Object
↳	com.google.android.material.animation.ArgbEvaluatorCompat

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

This compat version is copied from ArgbEvaluator with critical bug fixes for older versions of Android.

Summary

Public constructors
`ArgbEvaluatorCompat()`

Public methods
`Integer`	`evaluate(float fraction, Integer startValue, Integer 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.
`static ArgbEvaluatorCompat`	`getInstance()` Returns an instance of `ArgbEvaluatorCompat` that may be used in `ValueAnimator.setEvaluator(TypeEvaluator)`.

Public methods

evaluate

public Integer evaluate (float fraction, 
                Integer startValue, 
                Integer 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.

Parameters
`fraction`	`float`: The fraction from the starting to the ending values
`startValue`	`Integer`: A 32-bit int value representing colors in the separate bytes of the parameter
`endValue`	`Integer`: A 32-bit int value representing colors in the separate bytes of the parameter

Returns
`Integer`	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

public static ArgbEvaluatorCompat getInstance ()

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

Returns
`ArgbEvaluatorCompat`	An instance of `ArgbEvaluator`.
