How To Get Datepicker Value In Date Format?

I have a problem with my Datapicker i use the code for getting date,month & year shown below DatePicker datePicker; datePicker = (DatePicker) findViewByI

Solution 1:

You can format the date like this :

intday= datePicker.getDayOfMonth();
intmonth= datePicker.getMonth();
intyear= datePicker.getYear();
Calendar calendar = Calendar.getInstance();
calendar.set(year, month, day);

SimpleDateFormat sdf =new SimpleDateFormat("dd-MM-yyyy");
String formatedDate = sdf.format(calendar.getTime());

You can parse the String back to Date object by calling

Datedate= sdf.parse(formatedDate);

Solution 2:

publicStringcheckDigit(int number)
    {
        returnnumber<=9?"0"+number:String.valueOf(number);
    }

basic use:

month=checkDigit(month);
input 7
output 07
   String date=checkDigit(monthOfYear+1)+"/"+checkDigit(dayOfMonth)+"/"+year;

Solution 3:

<?xml version="1.0" encoding="utf-8"?>

<Button
    android:id="@+id/btnChangeDate"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Change Date" />

<TextView
    android:id="@+id/lblDate"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Current Date (M-D-YYYY): "
    android:textAppearance="?android:attr/textAppearanceLarge" />

<TextView
    android:id="@+id/tvDate"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text=""
    android:textAppearance="?android:attr/textAppearanceLarge" />

<DatePicker
    android:id="@+id/dpResult"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

                     year, month,day);
    }
    returnnull;
}

private DatePickerDialog.OnDateSetListenerdatePickerListener=newDatePickerDialog.OnDateSetListener() {

    // when dialog box is closed, below method will be called.publicvoidonDateSet(DatePicker view, int selectedYear,
            int selectedMonth, int selectedDay) {
        year = selectedYear;
        month = selectedMonth;
        day = selectedDay;

        // set selected date into textview
        tvDisplayDate.setText(newStringBuilder().append(month + 1)
           .append("-").append(day).append("-").append(year)
           .append(" "));

        // set selected date into datepicker also
        dpResult.init(year, month, day, null);

    }
};

}

Solution 4:

Starting from API level 12, DatePicker has public CalendarView getCalendarView (), using this view you can get the date:

long dateTime = datePicker.getCalendarView().getDate();
Datedate = newDate(dateTime);

Then format if needed:

DateFormatdateFormat=newSimpleDateFormat("dd-MM-yyyy");
StringformattedDate= dateFormat.format(date);

Solution 5:

You can use a custom method for setting date and month in the desired format

privatestaticStringpad(int c)
    {
        return c>=10 ? ""+c : "0"+c;      
    }

Instead of using the values for date and month use pad(date) and pad(month)

Hope this helps.
