我有一個TimePickerDialog與is24Hour設置爲false，因爲我想給最終用戶提供更熟悉的12小時格式。如果設置了小時，分鐘和AM PM指示燈並返回時間，我如何確定最終用戶是選擇了AM還是PM？TimePickerDialog和上午或下午
這就是我對聽衆：
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay,
int minute) {
mHour = hourOfDay;
mMinute = minute;
// mIsAM = WHERE CAN I GET THIS VALUE
}
};
的hourOfDay將永遠是24小時。如果您打開對話框is24HourView設置爲false，用戶將不必處理24小時格式化的時間，但Android會將其轉換爲24小時時間，當它調用onTimeSet()時。
我遇到了同樣的問題。我在我的應用程序中有一個TimePicker，在你選擇一個時間並點擊一個按鈕後，你將會進入一個顯示什麼時間被選中的屏幕。選擇的「時間」是正確的，但有時AM/PM的價值會與所選的相反。我最終通過改變我爲TimePicker中的「hrs」參數存儲的內容來修復它。
private TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener()
{
@Override
public void onTimeSet(TimePicker view, int hrs, int mins)
{
hour = hrs;
minute = mins;
c = Calendar.getInstance();
c.set(Calendar.HOUR_OF_DAY, hour);
//instead of c.set(Calendar.HOUR, hour);
c.set(Calendar.MINUTE, minute);
現在，當我點擊按鈕進入下一個屏幕時，它正確顯示了正確的AM/PM值。
的任何解決方案這是正確的答案，榮譽 – 2015-11-22 13:18:56
做到了這個把戲... thanx – Satyavrat 2016-03-31 06:11:23
這爲我工作：
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);
}
這是正是我正在尋找的！謝謝！ – LargeGlasses 2013-11-18 16:42:04
@LargeGlasses快樂，它幫助你:-) – 2013-11-18 19:37:33
感謝它完美的工作，罰款...... !!!! – 2014-06-03 11:45:21
嗨，你可以用你自己的格式如下：
String myFormat = "hh:mm a"; // your own format
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
String formated_time = sdf.format(calendar_time.getTime()); //format your time
我發現，「A」進行格式化時表示AM-PM代碼：http://www.tutorialspoint.com/java/java_date_time.htm

與選定的表示適當HH什麼用戶一個整潔的吐司信息：MM格式
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
String AM_PM = " AM";
String mm_precede = "";
if (hourOfDay >= 12) {
AM_PM = " PM";
if (hourOfDay >=13 && hourOfDay < 24) {
hourOfDay -= 12;
}
else {
hourOfDay = 12;
}
} else if (hourOfDay == 0) {
hourOfDay = 12;
}
if (minute < 10) {
mm_precede = "0";
}
Toast.makeText(mContext, "" + hourOfDay + ":" + mm_precede + minute + AM_PM, Toast.LENGTH_SHORT).show();
}
試試這個：
Calendar calendar = Calendar.getInstance();
calendar.set(0, 0, 0, hourOfDay, minute, 0);
long timeInMillis = calendar.getTimeInMillis();
java.text.DateFormat dateFormatter = new SimpleDateFormat("hh:mm a");
Date date = new Date();
date.setTime(timeInMillis);
time.setText(dateFormatter.format(date));
如果你的期望是直接設置AM/PM在時間選擇器對話框中，有一個變通。如果您預先使用當前/默認時間填充EditText，這將起作用。 - 在實例化對話框之前，如果EditText具有PM時間值，則將小時分量增加12。
sref_Time3是ampm值; sref_Time1是小時分量。
if (sref_Time3.equals("PM")) {
hour = hour + 12;
} else if (sref_Time1.equals("12")) {
hour = 0;
}
// Create a new instance of TimePickerDialog and return it
return new TimePickerDialog(getActivity(), this, hour, minute,
DateFormat.is24HourFormat(getActivity()));
謝謝&謝謝。
這個工作對我來說：
TimePickerDialog timePickerDialog = new TimePickerDialog(AddFocusActivity.this, new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
calendar.set(Calendar.MINUTE, minute);
calendar.set(Calendar.HOUR,hourOfDay);
time = calendar.get(Calendar.HOUR)
+ ((calendar.get(Calendar.AM_PM) == Calendar.AM) ? "am" : "pm");
Log.e("time",time);
}
},calendar.get(Calendar.HOUR_OF_DAY),calendar.get(Calendar.MINUTE), false);
private TimePickerDialog.OnTimeSetListener timeSetListener = new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
boolean isPM = (hourOfDay >= 12);
tvTime.setText(String.format("%02d:%02d %s", (hourOfDay == 12 || hourOfDay == 0) ? 12 : hourOfDay % 12, minute, isPM ? "PM" : "AM"));
}
};
public static class TimePickerFragment extends DialogFragment
implements TimePickerDialog.OnTimeSetListener {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current time as the default values for the picker
final Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR);
int minute = c.get(Calendar.MINUTE);
// Create a new instance of TimePickerDialog and return it
return new TimePickerDialog(getActivity(), this, hour, minute,
DateFormat.is24HourFormat(getActivity()));
}
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
Calendar calendar = Calendar.getInstance();
calendar.set(0, 0, 0, hourOfDay, minute);
textView.setText((String) DateFormat.format("hh:mm aaa", calendar));
}
}
//For showing the dialog put below two lines where you want to call
TimePickerFragment timePickerFragment = new TimePickerFragment();
timePickerFragment.show(getSupportFragmentManager(), "TimePicker");
試試這個簡單的方法：
void openTimeFragment() {
TimePickerDialog mTimePicker;
final Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR_OF_DAY);
int minute = c.get(Calendar.MINUTE);
mTimePicker = new TimePickerDialog(YourActivity.this, new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
String time = selectedHour + ":" + selectedMinute;
SimpleDateFormat fmt = new SimpleDateFormat("HH:mm");
Date date = null;
try {
date = fmt.parse(time);
} catch (ParseException e) {
e.printStackTrace();
}
SimpleDateFormat fmtOut = new SimpleDateFormat("hh:mm aa");
String formattedTime=fmtOut.format(date);
edtTextTime.setText(formattedTime);
}
}, hour, minute, false);//No 24 hour time
mTimePicker.setTitle("Select Time");
mTimePicker.show();
}
不錯，簡單的解決方案。謝謝:) – 2016-10-05 09:09:21

起初我忽略你的解決方案，並嘗試其他，但最後它解決了..很好的解決方案謝謝。 – 2017-08-31 05:31:23
private String getTime(int hr,int min) {
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY,hr);
cal.set(Calendar.MINUTE,min);
Format formatter;
formatter = new SimpleDateFormat("h:mm a");
return formatter.format(cal.getTime());
}
你可以試試我的解決方案，我用「HH：MM是」格式設置AM/PM時間：
SimpleDateFormat formatter = new SimpleDateFormat("hh:mm a", Locale.ENGLISH);
String formattedTime = formatter.format(myCalendar.getTime());
EditText.setText(formattedTime);
我知道這是太晚了答案，完美的答案已經被選中，但我認爲這對初學者不是很清楚，所以張貼我的答案
editText.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// TODO Auto-generated method stub
Calendar mcurrentTime = Calendar.getInstance();
int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
int minute = mcurrentTime.get(Calendar.MINUTE);
TimePickerDialog mTimePicker;
mTimePicker = new TimePickerDialog(getActivity(), new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
String AM_PM;
if (selectedHour >=0 && selectedHour < 12){
AM_PM = "AM";
} else {
AM_PM = "PM";
}
editText.setText(selectedHour + ":" + selectedMinute+" "+AM_PM);
}
}, hour, minute, false);
mTimePicker.setTitle("Select Time");
mTimePicker.show();
}
});
