Question

Is it possible to do that in a more convenient way than handling it in the OnScrollListener event? Pity it doesn’t have a step size attribute…

Answer 1

Why not just add an OnValueChangeListener Something like:

numberPicker.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() {

     @Override
     public void onValueChange(NumberPicker picker, int oldVal, int newVal) {
         picker.setValue((newVal < oldVal)?oldVal-5:oldVal+5);
     }

});
