Setting increase/decrease interval of NumberPicker

A bit late in the day, but this works for me...

    numberPicker.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() {
        @Override
        public void onValueChange(NumberPicker numberPicker, int oldVal, int newVal) {
            if (newVal > oldVal) {
                numberPicker.setValue(newVal+(myInterval-1));
            } else if (newVal < oldVal)
                numberPicker.setValue(newVal-(myInterval-1));
        }
    });
