Usage

From source file:android.support.wear.widget.util.ArcSwipe.java

private float[][] interpolate(float[] start, float[] end, int steps, boolean isClockwise) {
    float startAngle = getAngle(start[0], start[1]);
    float endAngle = getAngle(end[0], end[1]);

    Path path = new Path();
    PathMeasure pathMeasure = new PathMeasure();
    path.moveTo(start[0], start[1]);/*from  w w  w  .  ja v  a  2s . co m*/
    path.arcTo(mBounds, startAngle, getSweepAngle(startAngle, endAngle, isClockwise));
    pathMeasure.setPath(path, false);
    float pathLength = pathMeasure.getLength();

    float[][] res = new float[steps][2];
    float[] mPathTangent = new float[2];

    for (int i = 1; i < steps + 1; i++) {
        pathMeasure.getPosTan((pathLength * i) / (steps + 2f), res[i - 1], mPathTangent);
    }

    return res;
