Andriod向系统日历添加日程

1.检查是否有现有的账户存在

private static int checkCalendarAccount(Context context) {
        Cursor userCursor = context.getContentResolver().query(Uri.parse("content://com.android.calendar/calendars"), null, null, null, null);
        try {
            if (userCursor == null)//查询返回空值
                return -1;
            int count = userCursor.getCount();
            if (count > 0) {//存在现有账户，取第一个账户的id返回
                userCursor.moveToFirst();
                return userCursor.getInt(userCursor.getColumnIndex(CalendarContract.Calendars._ID));
            } else {
                return -1;
            }
        } finally {
            if (userCursor != null) {
                userCursor.close();
            }
        }
    }

2.添加账户

  private static long addCalendarAccount(Context context) {
        TimeZone timeZone = TimeZone.getDefault();
        ContentValues value = new ContentValues();
        value.put(CalendarContract.Calendars.NAME, "test");

        value.put(CalendarContract.Calendars.ACCOUNT_NAME, "test@163.com");
        value.put(CalendarContract.Calendars.ACCOUNT_TYPE, "com.android.exchange");
        value.put(CalendarContract.Calendars.CALENDAR_DISPLAY_NAME, "测试账户");
        value.put(CalendarContract.Calendars.VISIBLE, 1);
        value.put(CalendarContract.Calendars.CALENDAR_COLOR, Color.BLUE);
        value.put(CalendarContract.Calendars.CALENDAR_ACCESS_LEVEL, CalendarContract.Calendars.CAL_ACCESS_OWNER);
        value.put(CalendarContract.Calendars.SYNC_EVENTS, 1);
        value.put(CalendarContract.Calendars.CALENDAR_TIME_ZONE, timeZone.getID());
        value.put(CalendarContract.Calendars.OWNER_ACCOUNT, "test@163.com");
        value.put(CalendarContract.Calendars.CAN_ORGANIZER_RESPOND, 0);

        Uri calendarUri = Uri.parse("content://com.android.calendar/events");
        calendarUri = calendarUri.buildUpon()
                .appendQueryParameter(CalendarContract.CALLER_IS_SYNCADAPTER, "true")
                .appendQueryParameter(CalendarContract.Calendars.ACCOUNT_NAME, "test@163.com")
                .appendQueryParameter(CalendarContract.Calendars.ACCOUNT_TYPE, "com.android.exchange")
                .build();

        Uri result = context.getContentResolver().insert(calendarUri, value);
        long id = result == null ? -1 : ContentUris.parseId(result);
        return id;
    }

3.获取账户

 public static int checkAndAddCalendarAccount(Context context){
        int oldId = checkCalendarAccount(context);
        if( oldId >= 0 ){
            return oldId;
        }else{
            long addId = addCalendarAccount(context);
            if (addId >= 0) {
                return checkCalendarAccount(context);
            } else {
                return -1;
            }
        }
    }

3.添加日历事件

public static void addCalendarEvent(Context context,String title, String description, long beginTime){
    // 获取日历账户的id
    int calId = checkAndAddCalendarAccount(context);
    if (calId < 0) {
        // 获取账户id失败直接返回，添加日历事件失败
        return;
    }

    ContentValues event = new ContentValues();
    event.put("title", title);
    event.put("description", description);
    // 插入账户的id
    event.put("calendar_id", calId);

    Calendar mCalendar = Calendar.getInstance();
    mCalendar.setTimeInMillis(beginTime);//设置开始时间
    long start = mCalendar.getTime().getTime();
    mCalendar.setTimeInMillis(start + 60*1000);//设置终止时间
    long end = mCalendar.getTime().getTime();

    event.put(CalendarContract.Events.DTSTART, start);
    event.put(CalendarContract.Events.DTEND, end);
    event.put(CalendarContract.Events.HAS_ALARM, 1);//设置有闹钟提醒
    event.put(CalendarContract.Events.EVENT_TIMEZONE, "Asia/Shanghai");  //这个是时区，必须有，
    //添加事件
    Uri newEvent = context.getContentResolver().insert(Uri.parse("content://com.android.calendar/events"), event);
    if (newEvent == null) {
        // 添加日历事件失败直接返回
        return;
    }
    //事件提醒的设定
    ContentValues values = new ContentValues();
    values.put(CalendarContract.Reminders.EVENT_ID, ContentUris.parseId(newEvent));
    // 提前10分钟有提醒
    values.put(CalendarContract.Reminders.MINUTES, 10);
    values.put(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALERT);
    Uri uri = context.getContentResolver().insert(Uri.parse("content://com.android.calendar/reminders"), values);
    if(uri == null) {
        // 添加闹钟提醒失败直接返回
        ToastUtil.showToast(context , "添加失败");
        return;
    }else {
        ToastUtil.showToast(context , "添加成功");
    }
}

5.删除日历事件（根据设置的title）

public static void deleteCalendarEvent(Context context,String title){
    Cursor eventCursor = context.getContentResolver().query(Uri.parse("content://com.android.calendar/events"), null, null, null, null);
    try {
        if (eventCursor == null){
            ToastUtil.showToast(context , "没有查到该日程");
            return;
        }//查询返回空值

        if (eventCursor.getCount() > 0) {
            //遍历所有事件，找到title跟需要查询的title一样的项
            for (eventCursor.moveToFirst(); !eventCursor.isAfterLast(); eventCursor.moveToNext()) {
                String eventTitle = eventCursor.getString(eventCursor.getColumnIndex("title"));
                if (!TextUtils.isEmpty(title) && title.equals(eventTitle)) {
                    int id = eventCursor.getInt(eventCursor.getColumnIndex(CalendarContract.Calendars._ID));//取得id
                    Uri deleteUri = ContentUris.withAppendedId(Uri.parse("content://com.android.calendar/events"), id);
                    int rows = context.getContentResolver().delete(deleteUri, null, null);
                    if (rows == -1) {
                        //事件删除失败
                        ToastUtil.showToast(context , "删除失败");
                        return;
                    }else {
                        ToastUtil.showToast(context , "删除成功");
                    }
                }
            }
        }
    } finally {
        if (eventCursor != null) {
            eventCursor.close();
        }
    }
}
