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, ">>>>>>>");
}
});
}
}
