Change small part in an Android project

Hi, I have an android project, for simplification you can think of it as lyft or uber, I have done everything. I just want you to change the one who select the location or the destination to the driver and see if there is a customer who will go to the same destination, if there is, the driver can accept or refuse the customer. example: driver select a destination from his location ''x'' to destination ''b'' customer select destination ''b'' from his location ''y'' driver see the customer location which is ''y'' and can accept it or no. * No need for the driver or the customer to see the destination since they already chose it before searching for a ride.
