Question

Am developing an app, which first gets the current date from DatePicker using “Calendar.getInstance()”, and then the user changes the date. Now how do I fetch the new date after it has been changed?

Answer 1

declear this .

private static final int DATE_DIALOG_ID = 0;

add this coding in onCreate()

 // add a click listener to the button
    date_text.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            showDialog(DATE_DIALOG_ID);
        }
    });

    // get the current date      
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH); 
    String da = Integer.toString(mMonth)+"/"+Integer.toString(mDay)+"/"+Integer.toString(mYear);
    date_text.setText(da);

and this is out side of onCreate()

 private DatePickerDialog.OnDateSetListener mDateSetListener =
    new DatePickerDialog.OnDateSetListener() {
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        mYear = year;
        mMonth = monthOfYear;
        mDay = dayOfMonth;
        String selectedDate = Integer.toString(mMonth)+"/"+Integer.toString(mDay)+"/"+Integer.toString(mYear);
        date_text.setText(selectedDate);
        System.out.println("selected date is:"+selectedDate);
    }
};

@Override
protected Dialog onCreateDialog(int id)  {
    switch (id) {

    case DATE_DIALOG_ID:
        return new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);        
    }
    return null;
}
