I am creating a layout that will ask user enter destination(google places address), vehicle type, price offering and an optional message.
Is there any best way of making it simple for bike/car riders.
I would do the following:
I also think your text fields are still a little off (and the LATER button is placed slightly lower than the RIDE button). If I were you, I'd simply copy the material design guidelines to the teeth as they really help to get these "basics" down easily.
I'm just linking these since you're building a mobile service and I think it's way easier to follow these guidelines than to do it yourself (and the result will in 99% of the cases be better too).
