下拉控价Spinner的使用

public class MainActivity extends Activity {    private static final String TAG = MainActivity.class.getSimpleName();//获得类名    private Spinner mSpinner;//下拉控键    private String[] data = new String[]{"中国","湖南","湘潭","湘乡","小家"};    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        mSpinner = (Spinner) findViewById(R.id.spinner);        mSpinner.setAdapter(new ArrayAdapter<String>(                this,                android.R.layout.simple_list_item_1,                data));        mSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {            @Override            public void onItemSelected(AdapterView<?> arg0, View arg1,                    int position, long arg3) {                Log.e(TAG, data[position]);            }            @Override            public void onNothingSelected(AdapterView<?> arg0) {                //adapter为空的时候调用此方法                Log.e(TAG, ">>>>>>>");            }        });    }}
