今天我們來說說“Android怎么才可以讓系統(tǒng)日歷同步日程？”這個(gè)問題的階級(jí)方法和解決方法的代碼與思路。希望正在學(xué)習(xí)Android的小伙伴們有所收獲！
具體內(nèi)容如下
1、權(quán)限
<uses-permission android:name="android.permission.WRITE_CALENDAR" /> <uses-permission android:name="android.permission.READ_CALENDAR" />
2、動(dòng)態(tài)權(quán)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(shí)間：2022年12月31日23點(diǎn)59分59秒
String mRule = "";
switch (mRepeatType) {
case 1://不重復(fù)
mRule = null;
break;
case 2://按年重復(fù)(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(fù)（每月的某天）
mRule = "FREQ=MONTHLY;UNTIL=" + until + ";WKST=SU;BYMONTHDAY=" + day;
break;
case 4://按周重復(fù)
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(fù)，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(quán)限");
}
3、時(shí)間轉(zhuǎn)換方法
public static long stringToLong(String strTime, String formatType) {
Date date = null; // String類型轉(zhuǎn)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(zhuǎn)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(zhuǎn)換的date類型的時(shí)間
public static long dateToLong(Date date) {
return date.getTime();
}
