这篇文章主要介绍Android怎么实现系统日历同步日程，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
Android是一种基于Linux内核的自由及开放源代码的操作系统，主要使用于移动设备，如智能手机和平板电脑，由美国Google公司和开放手机联盟领导及开发。
Android实现系统日历同步日程的具体内容如下
1、权限
<uses-permission android:name="android.permission.WRITE_CALENDAR" /> <uses-permission android:name="android.permission.READ_CALENDAR" />
2、动态权限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";//截止时间：2022年12月31日23点59分59秒 String mRule = ""; switch (mRepeatType) { case 1://不重复 mRule = null; break; case 2://按年重复(每年的某月某日) mRule = "FREQ=YEARLY;UNTIL=" + until + ";WKST=SU;BYMONTH=" + month + ";BYMONTHDAY=" + day; break; case 3://按月重复（每月的某天） mRule = "FREQ=MONTHLY;UNTIL=" + until + ";WKST=SU;BYMONTHDAY=" + day; break; case 4://按周重复 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://自定义周几重复，可多选 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("插入失败"); } else if (addResult == -2) { ToastUtil.showShortToast("没有权限"); }3、时间转换方法
public static long stringToLong(String strTime, String formatType) { Date date = null; // String类型转成date类型 try { date = stringToDate(strTime, formatType); } catch (Exception e) { e.printStackTrace(); } if (date == null) { return 0; } else { long currentTime = dateToLong(date); // date类型转成long类型 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要转换的date类型的时间 public static long dateToLong(Date date) { return date.getTime(); }4、CalendarProviderManager 类
