Question

I’ve just started to learn Android, and I have a quick question. I have a separate class Team, and within it there’s 3 variables (String name, int goals, int points). In my main activity I want to increment the goals and/or points for each Team object once a button is clicked. At the moment I have a method:

        public void updatePoints(View v, Team t){
        t.points++;
        }

and in my xml file I have:

android:onClick="updatePoints"

which relates to a Button. Can I pass a Team object like above? If so, how can it be done?
As I said I’m only starting to learn Android so any advice would be a appreciated.

Cheers

Answer 1

If you have….

android:onClick="updatePoints" // in XML file

then in your java file you need to define…

public void updatePoints(View v){   
    // This is where you update each team

    // I think v.getId() retrieves the id of the button (or view) that was clicked
}

I assume in your activity you have…

Team team[]; // an array of teams (more than one), so you need to do something to identify the team your trying to update… so I’d change your definition of Team

public class Team {
    public int identity; // This is the new field
    public String name;
    public int goals;
    public int points;
}

Although you can, I wouldn’t use the tag property to identify a team… I’d use the identity field to identify individual teams. That way a team isn’t linked/tied to a button… more versatile IMHO
