Get week day from date-CodePudding

I'm building a Weather App for a project at uni. I'm trying to put the names of the week days instead of the dates. But for some reason it only writes Thursday. I can't figure what I'm missing.

This is what I tried. I get the myDate from a weather API and I've checked and all dates are right.

    var myDate = objData.getString("datetime")
    var date = SimpleDateFormat("yyyy-MM-dd").parse(myDate)
    val cal = Calendar.getInstance()
    cal.time = date
    var dayNumber = cal[Calendar.DAY_OF_WEEK]
    val formatter: DateFormat = SimpleDateFormat("EEEE", currentLocale)
    val dayWeek = formatter.format(dayNumber)
    findViewById<TextView>(R.id.textDay1).text = dayWeek

Appreciate any help.

Try the following code.

fun getWeekDay(dateString:String){
    val date = SimpleDateFormat("yyyy-MM-dd", Locale.getDefault()).parse(dateString)
    val calendar = Calendar.getInstance()
    calendar.time = date!!
    val formatter= SimpleDateFormat("EEEE", Locale.getDefault())
    val dayWeek = formatter.format(calendar.time)
    Log.e("TAG", "getWeekDay: $dayWeek" )
}
