Android Spinner控件，实现key(id)和Value的取值

实现方式：直接往适配器里面传对象，然后重写对象的toString()方法。

先声明一个对象，并重写对象的toString()。

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;
    }
}

然后声明对象实例并加入到arraylist里面,并设置spinner的适配器

Spinner spinner = (Spinner) findViewById(SpinnerViewID);
List<SpinnerData> lst = new ArrayList<SpinnerData>();

for (int i = 0; i < key.length; i++) {
    SpinnerData c = new SpinnerData(key[i], val[i]);
    lst.add(c);
}

ArrayAdapter<SpinnerData> Adapter = new ArrayAdapter<SpinnerData>(this,android.R.layout.simple_spinner_item, lst);

Adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(Adapter);

取得选中的值

/*spinnerID为R.id.xxx*/
//取得value
public String getSpinnerSelVal(Integer spinnerID){
    Spinner sp = (Spinner)findViewById(spinnerID);
    return ((SpinnerData)sp.getSelectedItem()).getValue();
}
//取得text
public String getSpinnerSelName(Integer spinnerID){
    Spinner sp = (Spinner)findViewById(spinnerID);
    return ((SpinnerData)sp.getSelectedItem()).getText();
}
