【Android】さくっと時刻とか月とか年を取得したい

More than 5 years have passed since last update.

getYear() とか getMonth() とかないのかよ!

ということでUtilを作る。

    public static int getYear() {
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        return calendar.get(Calendar.YEAR);
    }

    public static int getMonth() {
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        return calendar.get(Calendar.MONTH) + 1;
    }

    public static int getDay() {
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        return calendar.get(Calendar.DAY_OF_MONTH);
    }

    public static int getHour() {
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        return calendar.get(Calendar.HOUR_OF_DAY);
    }

    public static int getMinute() {
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        return calendar.get(Calendar.MINUTE);
    }

    public static int getSecond() {
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        return calendar.get(Calendar.SECOND);
    }

よしできた。

getMonth() だけちょっと注意が必要で、

return calendar.get(Calendar.MONTH) + 1;

1月が 0 から始まるので、そこだけ意図的に1を足してます。
