Question

每当有任何事件被添加到本地日历时，我都希望在我的应用中发出通知。我可以获取所有日历活动的列表，但是当前添加了新活动时我们没有收到通知。那么，请建议我任何有关相同的解决方案。

提前致谢。

获取所有活动清单的代码：

public class Utility {
    public static ArrayList<String> nameOfEvent = new ArrayList<String>();
    public static ArrayList<String> startDates = new ArrayList<String>();
    public static ArrayList<String> endDates = new ArrayList<String>();
    public static ArrayList<String> descriptions = new ArrayList<String>();

    public static ArrayList<String> readCalendarEvent(Context context) {
        Cursor cursor = context.getContentResolver()
                .query(
                        Uri.parse("content://com.android.calendar/events"),
                        new String[] { "calendar_id", "title", "description",
                                "dtstart", "dtend", "eventLocation" }, null,
                        null, null);
        cursor.moveToFirst();
        // fetching calendars name
        String CNames[] = new String[cursor.getCount()];

        // fetching calendars id
        nameOfEvent.clear();
        startDates.clear();
        endDates.clear();
        descriptions.clear();
        for (int i = 0; i < CNames.length; i++) {

            nameOfEvent.add(cursor.getString(1));
            startDates.add(getDate(Long.parseLong(cursor.getString(3))));
            endDates.add(getDate(Long.parseLong(cursor.getString(4))));
            descriptions.add(cursor.getString(2));
            CNames[i] = cursor.getString(1);
            cursor.moveToNext();

        }
        return nameOfEvent;
    }
public static String getDate(long milliSeconds) {
        SimpleDateFormat formatter = new SimpleDateFormat(
                "dd/MM/yyyy hh:mm:ss a");
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(milliSeconds);
        return formatter.format(calendar.getTime());
    }

如果您希望在日历更改时收到通知，则需要设置BroadcastReceiver并重新查询日历。

看到这个问题：

Listen to android calendar changes. (Sync/Delete/Insert etc..)

事件将添加到本地日历时收到通知
