how do i get the days of the week using kotlin in android studio?-CodePudding

I'm trying to get the days of the week to put in a weekly calendar on a screen. Basically it's getting the numbers of the days of the week and putting it in a textView, for example, today is the 25th, then taking this '25' and putting it in a textView and so on every day of the week, but I'm unsuccessful. I'm trying like this:

val calendar: Calendar = Calendar.getInstance()

    val day = calendar.add(Calendar.DAY_OF_MONTH, Calendar.TUESDAY)
    binding.txtNumeroTerca.text = day.toString()

[enter image description here][1]

when I run the app it looks like this, someone help please? [1]: https://i.stack.imgur.com/jw89K.jpg

CodePudding user response：

val day = Calendar.DAY_OF_WEEK.toString()
binding.txtNumeroTerca.text = day

It is because add() method returns nothing. If you want to get day of month, try something like that:

val calendar: Calendar = Calendar.getInstance()

calendar.add(Calendar.DAY_OF_MONTH, Calendar.TUESDAY)
val day= calendar.get(Calendar.DAY_OF_MONTH)

binding.txtNumeroTerca.text = day.toString()

And I recommend using numbers in add() method than code of week days.
