在android中将时间戳转换为当前日期

for displaying time I have used the following method:

private String getDate(long milliSeconds) {
    // Create a DateFormatter object for displaying date in specified
    // format.
    SimpleDateFormat formatter = new SimpleDateFormat("dd-mm-yyyy");
    // Create a calendar object that will convert the date and time value in
    // milliseconds to date.
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis((int) milliSeconds);
    return formatter.format(calendar.getTime());
} 

推荐答案

private String getDate(long time) {
    Calendar cal = Calendar.getInstance(Locale.ENGLISH);
    cal.setTimeInMillis(time * 1000);
    String date = DateFormat.format("dd-MM-yyyy", cal).toString();
    return date;
}

注意我把时间放在 setTimeInMillis 中，而不是 int，注意我的日期格式是 MM 而不是 mm(mm 是分钟，而不是月，这就是为什么你有一个月份应该是41"的值)

fun getDate(timestamp: Long) :String {
   val calendar = Calendar.getInstance(Locale.ENGLISH)
   calendar.timeInMillis = timestamp * 1000L
   val date = DateFormat.format("dd-MM-yyyy",calendar).toString()
   return date
}
