ミリ秒を日：時間：分：秒で表示する方法

これは私が今持っているものです

Seconds = (60 - timeInMilliSeconds / 1000 % 60);
Minutes = (60 - ((timeInMilliSeconds / 1000) / 60) %60);

私は正しいと思う。何時間も何日間も

Hours = ((((timeInMilliSeconds / 1000) / 60) / 60) % 24);
Days =  ((((timeInMilliSeconds / 1000) / 60) / 60) / 24)  % 24;

その後-

TextView.SetText("Time left:" + Days + ":" + Hours + ":" + Minutes + ":" + Seconds);

しかし、私の時間と日は間違っているようです

時間を計算する簡単な方法は、次のようなものを使用することです

long seconds = timeInMilliSeconds / 1000;
long minutes = seconds / 60;
long hours = minutes / 60;
long days = hours / 24;
String time = days + ":" + hours % 24 + ":" + minutes % 60 + ":" + seconds % 60;

これは28日以上ある場合は機能しますが、負の時間がある場合は機能しません。

SimpleDateFormatはあなたの友達です！ （私は今日それを発見しました、それは素晴らしいです。）

SimpleDateFormat formatter = new SimpleDateFormat("dd:HH:mm:ss", Locale.UK);

Date date = new Date(timeInMilliSeconds);
String result = formatter.format(date);

こんにちは、このコードはどうですか？

               0 ms -> 0 ms
             846 ms -> 846ms

Androidで経過時間/残り時間をフォーマットするには、Android.text.format.DateUtils、特にgetRelativeTimeSpanStringとformatElapsedTimeを使用します。

Joda-time APIを使用することもできます（ http://joda.org/joda-time/ ）

「クラスDateTimeFormatは、パターンによるフォーマットをサポートする単一のメソッドforPattern（String）を提供します。これらの「パターンベース」フォーマッタは、SimpleDateFormatのアプローチと同様のアプローチを提供します。」

LocalDate date = LocalDate.now();
DateTimeFormatter fmt = DateTimeFormat.forPattern("d MMMM, yyyy");
String str = date.toString(fmt);
