這篇文章主要介紹Android怎么實現系統日歷同步日程，文中介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們一定要看完！
Android是一種基于Linux內核的自由及開放源代碼的操作系統，主要使用于移動設備，如智能手機和平板電腦，由美國Google公司和開放手機聯盟領導及開發。
Android實現系統日歷同步日程的具體內容如下
1、權限
<uses-permission android:name="android.permission.WRITE_CALENDAR" /> <uses-permission android:name="android.permission.READ_CALENDAR" />
2、動態權限Activity中
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.WRITE_CALENDAR) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.WRITE_CALENDAR,
Manifest.permission.READ_CALENDAR}, 1);
}3、使用
String tipTime = "2021-04-25 12:00";
long start = TimeUtils.stringToLong(tipTime ,"yyyy-MM-dd HH:mm");
long end = start + 60 * 60 * 1000L;
LogUtil.d("start:" + start);
LogUtil.d("end:" + end);
String[] split = tipTime.split(" ");
String[] dateStr = split[0].split("-");
int month = Integer.parseInt(dateStr[1]);
int day = Integer.parseInt(dateStr[2]);
String until = "20221231T235959Z";//截止時間：2022年12月31日23點59分59秒
String mRule = "";
switch (mRepeatType) {
case 1://不重復
mRule = null;
break;
case 2://按年重復(每年的某月某日)
mRule = "FREQ=YEARLY;UNTIL=" + until + ";WKST=SU;BYMONTH=" + month + ";BYMONTHDAY=" + day;
break;
case 3://按月重復（每月的某天）
mRule = "FREQ=MONTHLY;UNTIL=" + until + ";WKST=SU;BYMONTHDAY=" + day;
break;
case 4://按周重復
String date = split[0];
String week = TimeUtils.getWeek(date);
switch (week) {
case "周日":
mRule = "FREQ=WEEKLY;UNTIL=" + until + ";WKST=SU;BYDAY=SU";
break;
case "周一":
mRule = "FREQ=WEEKLY;UNTIL=" + until + ";WKST=SU;BYDAY=MO";
break;
case "周二":
mRule = "FREQ=WEEKLY;UNTIL=" + until + ";WKST=SU;BYDAY=TU";
break;
case "周三":
mRule = "FREQ=WEEKLY;UNTIL=" + until + ";WKST=SU;BYDAY=WE";
break;
case "周四":
mRule = "FREQ=WEEKLY;UNTIL=" + until + ";WKST=SU;BYDAY=TH";
break;
case "周五":
mRule = "FREQ=WEEKLY;UNTIL=" + until + ";WKST=SU;BYDAY=FR";
break;
case "周六":
mRule = "FREQ=WEEKLY;UNTIL=" + until + ";WKST=SU;BYDAY=SA";
break;
}
break;
case 5://按天（每天）
mRule = "FREQ=DAILY;UNTIL=" + until;
break;
case 6://自定義周幾重復，可多選
mRule = "FREQ=WEEKLY;UNTIL=" + until + ";WKST=SU;BYDAY=";
String[] weeks = mSelectedWeekStr.split(",");
for (int i = 0; i < weeks.length; i++) {
if (weeks[i].equals("周日")) {
mRule += "SU,";
} else if (weeks[i].equals("周一")) {
mRule += "MO,";
} else if (weeks[i].equals("周二")) {
mRule += "TU,";
} else if (weeks[i].equals("周三")) {
mRule += "WE,";
} else if (weeks[i].equals("周四")) {
mRule += "TH,";
} else if (weeks[i].equals("周五")) {
mRule += "FR,";
} else if (weeks[i].equals("周六")) {
mRule += "SA,";
}
}
if (mRule.endsWith(",")) {
mRule.substring(0, mRule.length() - 1);
}
break;
}
LogUtil.d("mRule:" + mRule);
CalendarEvent calendarEvent = new CalendarEvent(
mContent, mContent,
"",
start,
end,
0, mRule
);
// 添加事件
int addResult = CalendarProviderManager.addCalendarEvent(AddScheduleActivity.this, calendarEvent);
if (addResult == 0) {
ToastUtil.showShortToast("插入成功");
} else if (addResult == -1) {
ToastUtil.showShortToast("插入失敗");
} else if (addResult == -2) {
ToastUtil.showShortToast("沒有權限");
}3、時間轉換方法
public static long stringToLong(String strTime, String formatType) {
Date date = null; // String類型轉成date類型
try {
date = stringToDate(strTime, formatType);
} catch (Exception e) {
e.printStackTrace();
}
if (date == null) {
return 0;
} else {
long currentTime = dateToLong(date); // date類型轉成long類型
return currentTime;
}
}
public static Date stringToDate(String strTime, String formatType) {
SimpleDateFormat formatter = new SimpleDateFormat(formatType);
Date date = null;
try {
date = formatter.parse(strTime);
} catch (ParseException e) {
e.printStackTrace();
}
return date;
}
// date要轉換的date類型的時間
public static long dateToLong(Date date) {
return date.getTime();
