Setting ID for Spinner items

Andrew picture Andrew · Apr 26, 2011 · Viewed 26.8k times · Source

I have an array of Strings I'm populating a Spinner object with. However, I'd like to attach an ID to each element of the Spinner, so when the user selects an item, I have its ID to use to save to some other piece of data. How can I do this?

Create a class StringWithTag and use in place of the string name in the list like so :-

public class StringWithTag {
    public String string;
    public Object tag;

    public StringWithTag(String stringPart, Object tagPart) {
        string = stringPart;
        tag = tagPart;
    }

    @Override
    public String toString() {
        return string;
    }
}

in the add items to spinner part :-

List<StringWithTag> list = new ArrayList<StringWithTag>();
list.add(new StringWithTag("Oldman", "12345"));
list.add(new StringWithTag("Umpire", "987654"));
list.add(new StringWithTag("Squad", "ABCDEE"));
ArrayAdapter<StringWithTag> adap = new ArrayAdapter<StringWithTag> (this, android.R.layout.simple_spinner_item, list);
....
....

in the listener :-

public void onItemSelected(AdapterView<?> parant, View v, int pos, long id) {
    StringWithTag s = (StringWithTag) parant.getItemAtPosition(pos);
    Object tag = s.tag;
}

voila! }
