ArgbEvaluatorCompat
public class ArgbEvaluatorCompat
This evaluator can be used to perform type interpolation between integer values that represent ARGB colors.
This compat version is copied from android.animation.ArgbEvaluator with critical bug fixes for older versions of Android.

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 | |
|---|---|
float fraction |
The fraction from the starting to the ending values |
Integer startValue |
A 32-bit int value representing colors in the separate bytes of the parameter |
Integer endValue |
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 setEvaluator. The same instance may be used in multiple Animators because it holds no state.
