如何從android中的timepicker獲取以毫秒爲單位的當前時間？

Question

我需要從timepicker獲得以毫秒爲單位的時間，以便以後我可以用當前時間檢查它，以執行一些活動。 任何幫助。

Answer 1

使用下面的代碼：

SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy hh:mm:ss"); 
String dateInString = "22-01-2015 10:20:56"; 
Date date = sdf.parse(dateInString); 

System.out.println(dateInString); 
System.out.println("Date - Time in milliseconds : " + date.getTime()); 

Calendar calendar = Calendar.getInstance(); 
calendar.setTime(date); 
System.out.println("Calender - Time in milliseconds : " + calendar.getTimeInMillis()); 

輸出：

的

22-01-2015 10:20:56 
Date - Time in milliseconds : 1421893256000 
Calender - Time in milliseconds : 1421893256000 

Answer 2

TimePickerDialog timePickerDialog = new TimePickerDialog(this, new OnTimeSetListener() { 

     @Override 
     public void onTimeSet(TimePicker view, int hourOfDay, int minute) { 
      final Calendar calendar = Calendar.getInstance(); 
      calendar.set(Calendar.HOUR_OF_DAY, hourOfDay); 
      calendar.set(Calendar.MINUTE, minute); 
      calendar.set(Calendar.SECOND, 0); 
      calendar.set(Calendar.MILLISECOND, 0); 

      long millis = calendar.getTimeInMillis(); 
     } 
    }, 10, 20, true);
