Android: how to get the current day of the week (Monday, etc…) in the user's language? (11 answers)

Closed 4 years ago.

I need to get a day string with only a day of week integer (example : 1 = monday, 5 = friday...), I don't have any date.

I know that I can define an array of string but I think there is a better solution by using a date format. Is it possible without having a date ?

回答1:

You can use the DayOfWeek enum to get a day by its number:

System.out.println(DayOfWeek.of(1).toString());

Output:

MONDAY

Answer found thanks to shmosel. I am using the following :

DateFormatSymbols.ge‌tInstance().getWeekda‌​ys()

回答3:

You can simply Make Array of string days and get day by Integer using indexing.......

String[] strDays = new String[] { "Sunday", "Monday", "Tuesday","Wednesday", "Thursday","Friday", "Saturday" };

// Day_OF_WEEK starts from 1 while array index starts from 0
    System.out.println("Current day is : " + strDays[0])

OutPut:

Sunday
