將月曆設置爲X月的月份

Question

我想從四個輸入構建的日曆對象中獲得一分鐘的時間：月（3rd），日（星期四），小時（1），分（30 ）和am/pm。另外，如果過去的時間應該增加一個月。

如何設置日曆到這個時間？

此代碼似乎沒有設置一天。小時，分鐘和上午/下午正確設置。

日曆設置：

long getTime() { 
    Calendar calendar = Calendar.getInstance(); 

    calendar.set(Calendar.DAY_OF_WEEK_IN_MONTH, getDayOfWeekInMonth()); 
    calendar.set(Calendar.DAY_OF_WEEK, getDayOfWeek()); 
    calendar.set(Calendar.HOUR, getHour()); 
    calendar.set(Calendar.MINUTE, getMinute()); 
    calendar.set(Calendar.AM_PM, getAmPm()); 

    if (System.currentTimeMillis() > calendar.getTimeInMillis()) { 
     calendar.add(Calendar.MONTH, 1); 
    } 

    return calendar.getTimeInMillis(); 

} 

int getDayOfWeekInMonth() { 
    return weekOfMonthSpinner.getSelectedItemPosition() + 1; 
} 

int getDayOfWeek() { 
    switch(dayOfWeekSpinner.getSelectedItemPosition()) { 
    case 0: 
     return Calendar.SUNDAY; 
    case 1: 
     return Calendar.MONDAY; 
    case 2: 
     return Calendar.TUESDAY; 
    case 3: 
     return Calendar.WEDNESDAY; 
    case 4: 
     return Calendar.THURSDAY; 
    case 5: 
     return Calendar.FRIDAY; 
    case 6: 
     return Calendar.SATURDAY; 
    default: 
     return 0; 
    } 
} 

int getHour() { 
    return Integer.parseInt((String) hourSpinner.getSelectedItem()); 
} 

int getMinute() { 
    return Integer.parseInt((String) minuteSpinner.getSelectedItem()); 
} 

int getAmPm() { 
    switch(amPmSpinner.getSelectedItemPosition()) { 
    case 0: 
     return Calendar.AM; 
    case 1: 
     return Calendar.PM; 
    default: 
     return 0; 
    } 
} 

微調設置：

<string-array name="week_of_month">

Answer 1

使用calendar.set(Calendar.WEEK_OF_MONTH, <week of the month>);和calendar.set(Calendar.DAY_OF_WEEK, 4);。

示例 -

Calendar calendar = Calendar.getInstance(); 
System.out.println("Before - "+calendar.getTime()); 
calendar.set(Calendar.WEEK_OF_MONTH, 3); 
calendar.set(Calendar.DAY_OF_WEEK, 4); 
System.out.println("After - "+calendar.getTime()); 

結果 -

Before - Tue Feb 12 23:23:28 IST 2013 
After - Wed Feb 13 23:18:16 IST 2013
