I am making an app in kotlin language. I want to change that Good morning textview to good evening when time is between 4 pm to 8pm and goodnight when time is in range of night time and agin to good morning when time pasts 12 am.

how can i do it in kotlin?

CodePudding user response：

Simply get hour like this:

val currentHour = Calendar.getInstance().get(Calendar.HOUR)

And set text, based on the hour.

text.text = if(currentHour > 20 && currentHour < 4) "Good evening" else "Good morning"
