Interpolator in XML about smoothprogressbar

[Diolor]

Got it app:spb_interpolator="spb_interpolator_decelerate"

Using android:interpolator="@android:anim/decelerate_interpolator" would be better indeed. I'll look at it, thanks

I investigated a bit more and found that you cannot specify custom interpolators via XML. Here is the source code:

if (name.equals("linearInterpolator")) {
    interpolator = new LinearInterpolator(c, attrs);
} else if (name.equals("accelerateInterpolator")) {
    interpolator = new AccelerateInterpolator(c, attrs);
} else if (name.equals("decelerateInterpolator")) {
    interpolator = new DecelerateInterpolator(c, attrs);
}  else if (name.equals("accelerateDecelerateInterpolator")) {
    interpolator = new AccelerateDecelerateInterpolator(c, attrs);
}  else if (name.equals("cycleInterpolator")) {
    interpolator = new CycleInterpolator(c, attrs);
} else if (name.equals("anticipateInterpolator")) {
    interpolator = new AnticipateInterpolator(c, attrs);
} else if (name.equals("overshootInterpolator")) {
    interpolator = new OvershootInterpolator(c, attrs);
} else if (name.equals("anticipateOvershootInterpolator")) {
    interpolator = new AnticipateOvershootInterpolator(c, attrs);
} else if (name.equals("bounceInterpolator")) {
    interpolator = new BounceInterpolator(c, attrs);
} else {
    throw new RuntimeException("Unknown interpolator name: " + parser.getName());
}

As I plan to add custom interpolators, it will be easier with the current implementation,
