1：首先定义一个类：ZxType.java

public class ZxType {    public String key;    //用于显示    public String value;//用于数据操作        public ZxType(String key,String value){        this.key = key;        this.value = value;    }        public String toString(){        return key;public String getID(){    return ID;}public String getValue(){    return Value;} }

2：ZxzxActivity.java

public class ZxzxActivity extends Activity {    private Spinner spZxzxType = null;    private ArrayAdapter<ZxType> adapter = null;    private ZxType zxTypeArr[] = null;        @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_zxzx);                spZxzxType = (Spinner)findViewById(R.id.spZxzxType);                getZxTypeArr();                adapter = new ArrayAdapter<ZxType>(                this,                android.R.layout.simple_spinner_item,                zxTypeArr            );                spZxzxType.setAdapter(adapter);                spZxzxType.setOnItemSelectedListener(listener);    }    private OnItemSelectedListener listener = new OnItemSelectedListener(){        @Override        public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,                long arg3) {            ZxType zxtype = (ZxType)spZxzxType.getSelectedItem();            String value = zxtype.value;            Toast.makeText(ZxzxActivity.this, value, Toast.LENGTH_SHORT).show();        }        @Override        public void onNothingSelected(AdapterView<?> arg0) {                    }    };            private void getZxTypeArr(){        zxTypeArr = new ZxType[]{                new ZxType("咨询类别",""),                new ZxType("重点税源模块","cc9890ee22ceff760122df0473210110"),                new ZxType("普通发票类","4028801b1c0bfe55011c0bfe89300002"),                new ZxType("专用发票类","4028801b1c0bfe55011c0bfea3310003"),                new ZxType("个体税收类","4028801b1c0bfe55011c0bfecc940004"),                new ZxType("税务登记类","4028801b1c0bfe55011c0bfeea2f0005"),                new ZxType("涉税资料填写类","4028801b1c0bfe55011c0bfeea2f0006"),                new ZxType("增值税类","4028801b1c0bfe55011c0bfeea2f0007"),                new ZxType("消费税类","4028801b1c0bfe55011c0bfeea2f0008"),                new ZxType("所得税类","4028801b1c0bfe55011c0bfeea2f0009"),                new ZxType("外商投资企业所得税类","4028801b1c0bfe55011c0bfeea2f0010"),                new ZxType("进出口税收类","4028801b1c0bfe55011c0bfeea2f0011"),                new ZxType("减免税类","4028801b1c0bfe55011c0bfeea2f0012"),                new ZxType("税收法规类","4028801b1c0bfe55011c0bfeea2f0013"),                new ZxType("其他类","4028801b1c0bfe55011c0bfeea2f0014"),                new ZxType("纳税申报类","4028801b1c0bfe55011c0bfeea2f0015"),                new ZxType("车辆购置税","4028801b1c0bfe55011c0bfeea2f0016"),                new ZxType("利息税","4028801b1c0bfe55011c0bfeea2f0017")        };    }}

取值：

如果取TEXT值则可以直接取:

spZxzxType.getSelectedItem.ToString()或者:((ZxType)spZxzxType.getSelectedItem). GetValue() ;

如果取Value值则可以这样取:((ZxType)spZxzxType .getSelectedItem).GetID();
