fun getTodayTime(timeStamp: Long): Long {
val cal = Calendar.getInstance()
cal.timeInMillis = timeStamp
cal.set(Calendar.HOUR_OF_DAY, 0)
cal.set(Calendar.SECOND, 0)
cal.set(Calendar.MINUTE, 0)
cal.set(Calendar.MILLISECOND, 0)
return cal.timeInMillis
}
fun isToday(time: Long): Boolean {
val sdf = SimpleDateFormat("yyyy-MM-dd")
val date = Date(time)
return try {
val old = sdf.parse(sdf.format(date))
val now = sdf.parse(sdf.format(Date()))
val oldTime = old.time
val nowTime = now.time
val day = (nowTime - oldTime) / (24 * 60 * 60 * 1000)
Log.d(TAG, "handleDate: day is ${day}")
if (day < 0) {
return false
}
if (day < 1) { //今天
// SimpleDateFormat format = new SimpleDateFormat("HH:mm");

} else if (day == 1L) { //昨天
// SimpleDateFormat format = new SimpleDateFormat("HH:mm");
// return "昨天 " + format.format(date);
Log.i(TAG, "is yesterday")
return false
} else { //可依次类推
// SimpleDateFormat format = new SimpleDateFormat("yyyy/MM/dd");
// return format.format(date);
Log.i(TAG, "no today no yesterday")
return false
}
} catch (e: Exception) {
