1.前言
工作中通常会将时间转化为几天几时几分几秒的格式,撸了一个工具类，懒得每次都使用一样的代码

public class FormatTime {
    public static final int MUNITE_MODE = 1;
    public static final int HOUR_MODE = 2;
    public static final int DAY_MODE = 3;
    private int mMode = MUNITE_MODE;
    private long mTotalTimeSeconde=0;
    public long res_day;
    public long res_hour;
    public long res_munite;
    public long res_second;

    public FormatTime setMode(int mode) {
        mMode = mode;
        return this;
    }

    public FormatTime setTimemillisecond(long totalTime) {
        mTotalTimeSeconde = totalTime / 1000;
        return this;
    }

    public FormatTime setTimeSecond(long totalTime) {
        mTotalTimeSeconde = totalTime;
        return this;
    }

    public FormatTime calculate() {
        switch (mMode) {
            case MUNITE_MODE:
                toMunite(mTotalTimeSeconde);
                break;
            case HOUR_MODE:
                toHour(mTotalTimeSeconde);
                break;
            case DAY_MODE:
                toDay(mTotalTimeSeconde);
                break;
        }
        return this;
    }


    /**
     * 转化为 几分几秒
     */
    private void toMunite(long totalTime) {
        res_munite = totalTime / 60;
        res_second = totalTime % 60;
    }

    /**
     * 转化为 几时几分几秒
     * @return
     */
    private void toHour(long totalTime) {

        res_hour = totalTime / 60 / 60;
        res_munite = totalTime / 60 % 60;
        res_second = totalTime % 60;
    }

    /**
     * 转化为 几天几时几分几秒
     * @return
     */
    private void toDay(long totalTime) {
        res_day = totalTime / (60 * 60 * 24);
        res_hour = (totalTime % (60 * 60 * 24)) / (60 * 60);
        res_munite = (totalTime % (60 * 60)) / (60);
        res_second = (totalTime % (60));
    }

}

2.使用方式(非常装逼的还是流式API哦)

 mFormatTime=new FormatTime();
 mFormatTime
                .setTimemillisecond(millisUntilFinished)
                .setMode(mMode)
                .calculate();

long day=mFormatTime.res_day;
long munite=mFormatTime.res_munite;
long second=mFormatTime.res_second;
