Question

我想通过timePickerDialog获取AM / PM值。我的代码是这样的，它通过timepickerdialog通过用户输入并设置警报。我在这里收到用户输入

datetime = Calendar.getInstance();
new TimePickerDialog(this,this,datetime.get(Calendar.HOUR),datetime.get(Calendar.MINUTE),false).show();

现在当onTimeSet函数调用i时，可以获得用户选择的小时和分钟，但无法获得用户选择的AM / PM值。这是其他代码

public void onTimeSet(TimePicker view, int hourOfDay, int minute) { try { Calendar time = Calendar.getInstance();
String am_pm;

if (datetime.get(Calendar.AM_PM) == Calendar.AM)
    am_pm = "AM";
else if (datetime.get(Calendar.AM_PM) == Calendar.PM)
    am_pm = "PM";

time.set(Calendar.HOUR, hourOfDay);
time.set(Calendar.MINUTE, minute);
//time.set(Calendar.SECOND, 0);
//time.set(Calendar.MILLISECOND, 0);
//time.set(Calendar.AM_PM,datetime.PM);

AlarmManager alarmMgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, AlarmReceiver.class);

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);      
alarmMgr.set(AlarmManager.RTC_WAKEUP,time.getTimeInMillis(), pendingIntent);
Toast.makeText(this, "Alarm Set", Toast.LENGTH_long);

在侦听器中创建新的日历实例，如下所示

Calendar datetime = Calendar.getInstance();
     c.set(Calendar.HOUR, mHour);
    c.set(Calendar.MINUTE, mMinute);

    if (datetime.get(Calendar.AM_PM) == Calendar.AM)
        am_pm = "AM";
    else if (datetime.get(Calendar.AM_PM) == Calendar.PM) {
        am_pm = "PM";
         if (hourOfDay > 12)
              hourOfDay = hourOfDay - 12;
    }

已更新：

Calendar mCalendar = Calendar.getInstance();

 mHour = mCalendar.get(Calendar.HOUR_OF_DAY);
 mMinute = mCalendar.get(Calendar.MINUTE);


 TimePickerDialog timePickerDialog = new TimePickerDialog(mActivity, mTimeSetListener, mHour, mMinute, false);

 private TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() {
     public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

         mCalendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
         mCalendar.set(Calendar.MINUTE, mMinute);
         SimpleDateFormat mSDF = new SimpleDateFormat("hh:mm a");
         String time = mSDF.format(mCalendar.getTime());
     }
 }

也许这可以回答你的问题。

TimePickerDialog and AM or PM

Answer 3

试试这个：

public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
    String am_pm = "";

    Calendar datetime = Calendar.getInstance();
    datetime.set(Calendar.HOUR_OF_DAY, hourOfDay);
    datetime.set(Calendar.MINUTE, minute);

    if (datetime.get(Calendar.AM_PM) == Calendar.AM)
        am_pm = "AM";
    else if (datetime.get(Calendar.AM_PM) == Calendar.PM)
        am_pm = "PM";

    String strHrsToShow = (datetime.get(Calendar.HOUR) == 0) ?"12":datetime.get(Calendar.HOUR)+""; 

    ((Button)getActivity().findViewById(R.id.btnEventStartTime)).setText( strHrsToShow+":"+datetime.get(Calendar.MINUTE)+" "+am_pm );
}
