↳ | android.animation.IntArrayEvaluator |
This evaluator can be used to perform type interpolation between int[]
values.
Each index into the array is treated as a separate value to interpolate. For example,
evaluating {100, 200}
and {300, 400}
will interpolate the value at
the first index between 100 and 300 and the value at the second index value between 200 and 400.

Create an IntArrayEvaluator that does not reuse the animated value. Care must be taken
when using this option because on every evaluation a new int[]
will be
allocated.
Create an IntArrayEvaluator that reuses reuseArray
for every evaluate() call.
Caution must be taken to ensure that the value returned from
getAnimatedValue()
is not cached, modified, or
used across threads. The value will be modified on each evaluate()
call.
reuseArray | The array to modify and return from evaluate .
|
---|
Interpolates the value at each index by the fraction. If IntArrayEvaluator(int[])
was used to construct this object, reuseArray
will be returned, otherwise
a new int[]
will be returned.
fraction | The fraction from the starting to the ending values |
---|---|
startValue | The start value. |
endValue | The end value. |
int[]
where each element is an interpolation between
the same index in startValue and endValue.
