uj5u.com熱心網友回復：
想讓spinner默認為系統時間datam，該怎么寫？uj5u.com熱心網友回復：
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener(){
public void onNothingSelected(AdapterView<?> parent) {
}
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String cityName = (String) adapter.getItem(position);
}
});
