Setting time and date to date picker and time picker in android
I am using a date picker and time picker in my application. I want to set the date and time when the page loads. Is this possible? How so?
I solved a similar problem of mine as follows
Calendar cal = Calendar.getInstance();
int year = cal.get(Calendar.YEAR);
int month = cal.get(Calendar.MONTH);
int day = cal.get(Calendar.DAY_OF_MONTH);
int hour = cal.get(Calendar.HOUR_OF_DAY);
int min = cal.get(Calendar.MINUTE);
datePicker.updateDate(year, month, day);
timePicker.setCurrentHour(hour);
timePicker.setCurrentMinute(min);
Using JodaTime
JodaTime is an extremely popular and useful library for handling dates and times in Java. If you're not using it, I highly recommend taking a look at it.
Here's a simple example of how I set a DatePicker
and TimePicker
from a DateTime
object, which could be the current date or any date from the past or future (the attribute in this case is called inspected_at
):
DatePicker datePicker = (DatePicker) findViewById(R.id.inspected_at_date);
TimePicker timePicker = (TimePicker) findViewById(R.id.inspected_at_time);
DateTime inspected_at = DateTime.now() // Typically pulled from DB.
int year = inspected_at.getYear() ;
int month = inspected_at.getMonthOfYear() - 1; // Need to subtract 1 here.
int day = inspected_at.getDayOfMonth();
int hour = inspected_at.getHourOfDay();
int minutes = inspected_at.getMinuteOfHour();
datePicker.updateDate(year, month, day); // Set date.
timePicker.setCurrentHour(hour); // Set time.
timePicker.setCurrentMinute(minutes);
Hope that helps.

There is a updateDate
method for the DatePicker.
Here is what I use in one of my app, not using a dialog:
//set datePicker to position
String date_saved = project_row.getString(
project_row.getColumnIndex("project_startdate"));
int day = Integer.parseInt(date_saved.substring(0,2));
int year = Integer.parseInt(date_saved.substring(5,9));
String month = date_saved.substring(2,5);
int month_code = getMonthInt(month);
project_startdate_data = (DatePicker) findViewById(R.id.project_startdate_data);
project_startdate_data.updateDate(year, month_code, day);
where project_row
is my cursor, and the date is saved in the column project_startdate
like 22MAY2012
and you need this:
private int getMonthInt(String month) {
if (month.equalsIgnoreCase("JAN")) return 0;
if (month.equalsIgnoreCase("FEB")) return 1;
if (month.equalsIgnoreCase("MAR")) return 2;
if (month.equalsIgnoreCase("APR")) return 3;
if (month.equalsIgnoreCase("MAY")) return 4;
if (month.equalsIgnoreCase("JUN")) return 5;
if (month.equalsIgnoreCase("JUL")) return 6;
if (month.equalsIgnoreCase("AUG")) return 7;
if (month.equalsIgnoreCase("SEP")) return 8;
if (month.equalsIgnoreCase("OCT")) return 9;
if (month.equalsIgnoreCase("NOV")) return 10;
if (month.equalsIgnoreCase("DEC")) return 11;
//return -1 if month code not found
return -1;
}
Check this How to use date picker dialog. and use update function in onCreate(); if by page loads you mean activity starts.... hope it helps.
