TimePickerDialog and AM or PM
a neat toast message with what user selected showing proper HH:MM format
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();
}
I was running into the same problem. I have a TimePicker in my app where after you choose a time and hit a button you'll be taken to a screen that showed what time was chosen. The "time" chosen was correct but sometimes the AM/PM value would be opposite of what was chosen. I finally fixed it by changing what I was storing for the "hrs" argument from the TimePicker.
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);
Now when I hit the button to go to the next screen it properly showed the correct AM/PM value chosen.
This worked for me:
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 );
}
The hourOfDay
will always be 24-hour. If you opened the dialog with is24HourView
set to false
, the user will not have to deal with 24-hour formatted times, but Android will convert that to a 24-hour time when it calls onTimeSet()
.
