I am planning to create a rate convertor for food recipes. The user has to introduce the quantity of some food and then select the unit (gr,kg,mg,cl...). First of all I think in seekbar, but as the quantity could be infinite the seekbar doesn't make sense.
The best approach I can think of is: +[EditBox]- [Select unit(gr,Kg)…]
What do you think is the best option? Do you have any tip or advice?
