Android Timepicker問題

Question

我試圖從我的TimePicker小部件中提取選定的時間，但是當我使用getCurrentHour()和getCurrentMinute()方法時，它會一直返回當前時間而不是我選擇的時間。

而且具有選定的不同時間記錄的logcat的那些顯示

任何修復建議？

你應該用你取回的OnTimeSetListener

public void onTimeSet(TimePicker view, int hourOfDay, int minute) { 
    // Do something with the time chosen by the user 
} 

回調的時間，你可以看到一個例子HERE

顯然，你需要迫使它失去焦點，則值更新

// force the timepicker to loose focus and the typed value is available ! 
timePicker.clearFocus(); 
// re-read the values, in my case i put them in a Time object. 
time.hour = timePicker.getCurrentHour(); 
time.minute = timePicker.getCurrentMinute();
