I have a string "2015-02-24", how can I get "day name like Monday or Mon" in android. I try to use the code below but failed.
SimpleDateFormat sdf = new SimpleDateFormat("EEEE");
Date d = new Date("2015-02-24");
String dayOfTheWeek = sdf.format(d);
String input_date_string="2015-02-24";
SimpleDateFormat dateformat=new SimpleDateFormat("yyyy-MM-dd");
Date date;
try {
date = dateformat.parse(input_date_string);
DateFormat dayFormate=new SimpleDateFormat("EEEE");
String dayFromDate=dayFormate.format(date);
Log.d("asd", "----------:: "+dayFromDate);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Use Calender instance or use DateFormat
Simple :
Calendar c = Calendar.getInstance();
c.setTime(yourDate);
int dayOfWeek = c.get(Calendar.DAY_OF_WEEK);
Or:
String dayOfTheWeek = (String) android.text.format.DateFormat.format("EEEE", date);//Thursday
String stringMonth = (String) android.text.format.DateFormat.format("MMM", date); //Jun
String intMonth = (String) android.text.format.DateFormat.format("MM", date); //06
String year = (String) android.text.format.DateFormat.format("yyyy", date); //2013
String day = (String) android.text.format.DateFormat.format("dd", date); //20
UPDATE: you have to see Date in Java doc:
Constructor Summary:
Date(): Allocates a Date object and initializes it so that it represents the time at which it was allocated, measured to the nearest millisecond.
Date(int year, int month, int date): Deprecated. As of JDK version 1.1, replaced by Calendar.set(year + 1900, month, date) or GregorianCalendar(year + 1900, month, date).
Date(int year, int month, int date, int hrs, int min): Deprecated. As of JDK version 1.1, replaced by Calendar.set(year + 1900, month, date, hrs, min) or GregorianCalendar(year + 1900, month, date, hrs, min).
Date(int year, int month, int date, int hrs, int min, int sec): Deprecated. As of JDK version 1.1, replaced by Calendar.set(year + 1900, month, date, hrs, min, sec) or GregorianCalendar(year + 1900, month, date, hrs, min, sec).
Date(long date): Allocates a Date object and initializes it to represent the specified number of milliseconds since the standard base time known as "the epoch", namely January 1, 1970, 00:00:00 GMT.
Date(String s): Deprecated. As of JDK version 1.1, replaced by DateFormat.parse(String s).
Only Date() and Date(long Date) still usable.
You need to first convert the date in String format to a Date object. This can be done via:
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
Date date = dateFormat.parse(date);
You can then format the above date via:
SimpleDateFormat weekDayFormat = new SimpleDateFormat("EEEE");
String dayOfTheWeek = weekDayFormat.format(date);
All the answers are correct. I am just summing up the essence of all.
First you need to parse your String into Date, like this:
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
try {
Date date = dateFormat.parse("2015-02-24");
}
catch (ParseException e) {
e.printStackTrace();
}
Your date is ready :)
But major functions of Date class are deprecated. So you should use Calendar instead. Like this:
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
int dayOfWeek = calendar.get(Calendar.DAY_OF_WEEK);
switch(dayOfWeek)
{
case Calendar.SUNDAY:
break;
case Calendar.MONDAY:
break;
case Calendar.TUESDAY:
break;
case Calendar.WEDNESDAY:
break;
case Calendar.THURSDAY:
break;
case Calendar.FRIDAY:
break;
case Calendar.SATURDAY:
break;
}
Now with calendar, you can get any thing you want. Here is more information for Calendar on Android Docs.
