TimePicker - how to get AM or PM? [duplicate]

Answer 1

I would've preferred to leave this as a comment, but I don't have enough reputation. By far the most succinct way to get AM or PM is using the ternary operator:

String am_pm = (hourOfDay < 12) ? "AM" : "PM";

Answer 2

You can get AM/PM from Timepicker using following method. Timepicker is a viewgroup.That's why we can get its child view index 2 which demonstrates AM/PM is actually a button. So we can get its text.

 Mycallback=new OnTimeSetListener() {

        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        ViewGroup vg=(ViewGroup) view.getChildAt(0);
            Toast.makeText(TimePickerDemoActivity.this, hourOfDay+":"+minute+":"+((Button)vg.getChildAt(2)).getText().toString(), 5000).show();

        }
    };

Answer 3

I did it using Calendar, and that should work on all versions:

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":Integer.toString( datetime.get(Calendar.HOUR) );


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

Notice the use of Calendar.HOUR_OF_DAY and Calendar.HOUR if you go to the documentation of both you'd know the trick.

Here I'm taking the current date and time from the system and updating it with date and time picker dialog

private int  mMonth,mYear,mDay,mHour,mMin;

public static final int DTPKR = 1;

public static final int TMPKR = 2;

// Getting  the current date and time into DatePicker dialog

    public void getCurrentDate(){
       final Calendar c = Calendar.getInstance();
        mYear = c.get(Calendar.YEAR);
        mMonth = c.get(Calendar.MONTH);
        mDay = c.get(Calendar.DAY_OF_MONTH);
    } 

    public void getCurrentTime(){
                final Calendar c = Calendar.getInstance();
            mHour = c.get(Calendar.HOUR_OF_DAY);
            mMin = c.get(Calendar.MINUTE);

      } 

Now create the dialogs and update the values //Creating dialogs

    protected Dialog onCreateDialog(int id) {
        switch (id) {
        case DTPKR:
            return new DatePickerDialog(this,lisDate, mYear, mMonth, mDay);
        case TMPKR:
            return new TimePickerDialog(this,lisTime,mHour, mMin, false);
        }
        return null;
    }

    //setting date and updating editText 

       DatePickerDialog.OnDateSetListener lisDate = new DatePickerDialog.OnDateSetListener() {
               @Override
               public void onDateSet(DatePicker view, int year, int monthOfYear,
                 int dayOfMonth) {
                   mYear = year;
                    mMonth = monthOfYear;
                    mDay = dayOfMonth;
                etDate.setText(new StringBuilder() .append(mDay).append("/").append(mMonth+1).append("/").append(mYear));
                getCurrentDate();     

             }
    };

  //setting time and updating editText 

    TimePickerDialog.OnTimeSetListener lisTime=new TimePickerDialog.OnTimeSetListener() {

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            mHour=hourOfDay;
            mMin=minute;

             String AM_PM ;
                if(hourOfDay < 12) {
                    AM_PM = "AM";

                } else {
                    AM_PM = "PM";
                    mHour=mHour-12;
                }
                etTime.setText(mHour+":"+mMin+" "+AM_PM);
                getCurrentDate();
        }
    };

Answer 5

Above answers are right i found simplest way to find AM PM.

TimePickerDialog.OnTimeSetListener onStartTimeListener = new OnTimeSetListener() {

    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        String AM_PM ;
        if(hourOfDay < 12) {
            AM_PM = "AM";
        } else {
            AM_PM = "PM";
        }

        mStartTime.setText(hourOfDay + " : " + minute + " " + AM_PM );
    }
};

Answer 6

e.g :

TimePicker sellerTime = (TimePicker) findViewById(R.id.sellerTime);

Integer.toString(((sellerTime.getCurrentHour().intValue()) > 12) ?  ((sellerTime.getCurrentHour().intValue()) - 12) : 
(sellerTime.getCurrentHour().intValue())
