Android Studio - Metro Lines by City List View (3 Activities)











up vote

favorite












I'm trying to implement a simple selection of the Metro lines by city.
I have an array with the cities and an array of arrays with the metro lines related to that city. All in the Main Activity.



When I click ie "Porto" a new activity (Activity2) opens up with the lines from "Porto".



For each line there's a more detailed information about the capacity, the company and the line itself. (1 to 1)
The objective is when I click the line a new activity (Activity3) opens up with a more detailed information.



This is just an academic example to understand how to work with information between activities. No database included.



What's the best way to achieve that?



You can check the java code in the link below.
