Date Comparison In Android

I'm facing some problems in comparing the current date and the date which is retrieved from Database.I just retrieved date from DataBase and Stored in a Date variable like this Str

Solution 1:

For exact match including milliseconds, use getTime:

if(date.getTime() == date1.getTime()){
   //do something
} 

Solution 2:

You can use this function:

private boolean compareDates(Calendar objCal1, Calendar objCal2) {

  return ((objCal1.get(Calendar.YEAR) == objCal2.get(Calendar.YEAR))
    && (objCal1.get(Calendar.DAY_OF_YEAR) == objCal2.get(Calendar.DAY_OF_YEAR)));
}

creating the calendar objects:

CalendarobjCal1=newGregorianCalendar().setTime(date);
CalendarobjCal2=newGregorianCalendar().setTime(date1);

Solution 3:

Try this way to get the current date,

CalendarcalCurr= Calendar.getInstance();
Log.i("Time in mili of Current - Normal", ""+calCurr.getTimeInMillis()); // see what it gives? dont know why?Datedate=newDate();
calCurr.set(date.getYear()+1900, date.getMonth()+1, date.getDate(), date.getHours(), date.getMinutes(), date.getSeconds());// so added one month to it
Log.i("Time in mili of Current - after update", ""+calCurr.getTimeInMillis()); // now get correct

now create Calendar object for database value,

String due_date_task = cursor.getString(cursor.getColumnIndex(dueDateOfTask));      

SimpleDateFormat currentFormater = new SimpleDateFormat("dd/MM/yyyy");      
Datedate = currentFormater.parse(due_date_task);     
Calendar start = Calendar.getInstance();
start.set(date.getYear(), date.getMonth(), date.getDate(), date.getHours(), date.getMinutes(), date.getSeconds());

and now Compare both the Calendar objects

if(calCurr.equals(start))
