Spinner text 和 value

定義spinner data結構

public class SpinnerData {
    private String value = "";
    private String text = "";

    public SpinnerData() {
        value = "";
        text = "";
    }

    public SpinnerData(String _value, String _text) {
        value = _value;
        text = _text;
    }

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

    public String getValue() {
        return value;
    }

    public String getText() {
        return text;
    }
}

設定Spinner adapter

        List<SpinnerData> list = new ArrayList<SpinnerData>();
        SpinnerData sd = new SpinnerData(value, text);
        list.add(sd);

        ...
        ...
        ...

        ArrayAdapter<SpinnerData> adapter = new ArrayAdapter<SpinnerData>(context, android.R.layout.simple_spinner_item, list);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        sp.setAdapter(adapter);

get Spinner value/text

String value = ((SpinnerData) spinner.getSelectedItem()).getValue();
String text = ((SpinnerData) spinner.getSelectedItem()).getText();
