Java 年月日和nuix时间戳的转换

unix时间戳是秒级时间戳
date需要毫秒级时间戳
在配上格式化字符串与Calendar
完成时间戳的转换

    <string name="time_format">%1$d年%2$d月%3$d日%4$d时%5$d分</string>

public static String timeStamp2Date(long timestamp) {
        timestamp = timestamp * 1000;
        Date date = new Date(timestamp);
        Calendar cal = Calendar.getInstance();
        cal.setTime(date);
        Resources resources = GlobalContext.getContext().getResources();
        String suffix = String.format(resources.getString(R.string.time_format), cal.get(Calendar.YEAR), cal.get(Calendar.MONTH) + 1, cal.get(Calendar.DAY_OF_MONTH), cal.get(Calendar.HOUR_OF_DAY), cal.get(Calendar.MINUTE));
        return resources.getString(R.string.disallowcomment_prefix) + suffix;
    }

或者

new SimpleDateFormat("yyyy年MM月dd日HH时mm分").format(date)

第二种方法会带0
