如何在Android中添加日历活动？

Question

我刚刚开始使用Android,今天在项目会议上有人说Android没有原生日历应用程序,所以用户只需使用他们喜欢的任何日历应用程序.

这是真的,如果是这样,我如何以编程方式将事件添加到用户的日历中？他们共有一个共同的API吗？

对于它的价值,我们可能会瞄准Android 2.x.

Answer 1

在您的代码中尝试此操作:

Calendar cal = Calendar.getInstance();              
Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
intent.putExtra("beginTime", cal.getTimeInMillis());
intent.putExtra("allDay", true);
intent.putExtra("rrule", "FREQ=YEARLY");
intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
intent.putExtra("title", "A Test Event from android app");
startActivity(intent);

Answer 2

在您的代码中使用此API ..它将帮助您插入事件,带有提醒的事件和可以启用会议的事件...此api适用于平台2.1及更高版本使用少于2.1而不是content:// com的用户.android.calendar/events使用content:// calendar/events

 public static long pushAppointmentsToCalender(Activity curActivity, String title, String addInfo, String place, int status, long startDate, boolean needReminder, boolean needMailService) {
    /***************** Event: note(without alert) *******************/

    String eventUriString = "content://com.android.calendar/events";
    ContentValues eventValues = new ContentValues();

    eventValues.put("calendar_id", 1); // id, We need to choose from
                                        // our mobile for primary
                                        // its 1
    eventValues.put("title", title);
    eventValues.put("description", addInfo);
    eventValues.put("eventLocation", place);

    long endDate = startDate + 1000 * 60 * 60; // For next 1hr

    eventValues.put("dtstart", startDate);
    eventValues.put("dtend", endDate);

    // values.put("allDay", 1); //If it is bithday alarm or such
    // kind (which should remind me for whole day) 0 for false, 1
    // for true
    eventValues.put("eventStatus", status); // This information is
    // sufficient for most
    // entries tentative (0),
    // confirmed (1) or canceled
    // (2):
    eventValues.put("eventTimezone", "UTC/GMT +2:00");
   /*Comment below visibility and transparency  column to avoid java.lang.IllegalArgumentException column visibility is invalid error */

    /*eventValues.put("visibility", 3); // visibility to default (0),
                                        // confidential (1), private
                                        // (2), or public (3):
    eventValues.put("transparency", 0); // You can control whether
                                        // an event consumes time
                                        // opaque (0) or transparent
                                        // (1).
      */
    eventValues.put("hasAlarm", 1); // 0 for false, 1 for true

    Uri eventUri = curActivity.getApplicationContext().getContentResolver().insert(Uri.parse(eventUriString), eventValues);
    long eventID = Long.parseLong(eventUri.getLastPathSegment());

    if (needReminder) {
        /***************** Event: Reminder(with alert) Adding reminder to event *******************/

        String reminderUriString = "content://com.android.calendar/reminders";

        ContentValues reminderValues = new ContentValues();

        reminderValues.put("event_id", eventID);
        reminderValues.put("minutes", 5); // Default value of the
                                            // system. Minutes is a
                                            // integer
        reminderValues.put("method", 1); // Alert Methods: Default(0),
                                            // Alert(1), Email(2),
                                            // SMS(3)

        Uri reminderUri = curActivity.getApplicationContext().getContentResolver().insert(Uri.parse(reminderUriString), reminderValues);
    }

    /***************** Event: Meeting(without alert) Adding Attendies to the meeting *******************/

    if (needMailService) {
        String attendeuesesUriString = "content://com.android.calendar/attendees";

        /********
         * To add multiple attendees need to insert ContentValues multiple
         * times
         ***********/
        ContentValues attendeesValues = new ContentValues();

        attendeesValues.put("event_id", eventID);
        attendeesValues.put("attendeeName", "xxxxx"); // Attendees name
        attendeesValues.put("attendeeEmail", "yyyy@gmail.com");// Attendee
                                                                            // E
                                                                            // mail
                                                                            // id
        attendeesValues.put("attendeeRelationship", 0); // Relationship_Attendee(1),
                                                        // Relationship_None(0),
                                                        // Organizer(2),

        attendeesValues.put("attendeeType", 0); // None(0), Optional(1),
                                                // Required(2), Resource(3)
        attendeesValues.put("attendeeStatus", 0); // NOne(0), Accepted(1),
                                                    // Decline(2),
                                                    // Invited(3),
                                                    // Tentative(4)

        Uri attendeuesesUri = curActivity.getApplicationContext().getContentResolver().insert(Uri.parse(attendeuesesUriString), attendeesValues);
    }

    return eventID;

我使用下面的代码,它解决了我的问题,在ICS中的默认设备日历中添加事件,以及减少ICS的版本

    if (Build.VERSION.SDK_INT >= 14) {
        Intent intent = new Intent(Intent.ACTION_INSERT)
        .setData(Events.CONTENT_URI)
        .putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, beginTime.getTimeInMillis())
        .putExtra(CalendarContract.EXTRA_EVENT_END_TIME, endTime.getTimeInMillis())
        .putExtra(Events.TITLE, "Yoga")
        .putExtra(Events.DESCRIPTION, "Group class")
        .putExtra(Events.EVENT_LOCATION, "The gym")
        .putExtra(Events.AVAILABILITY, Events.AVAILABILITY_BUSY)
        .putExtra(Intent.EXTRA_EMAIL, "rowan@example.com,trevor@example.com");
         startActivity(intent);
}

    else {
        Calendar cal = Calendar.getInstance();              
        Intent intent = new Intent(Intent.ACTION_EDIT);
        intent.setType("vnd.android.cursor.item/event");
        intent.putExtra("beginTime", cal.getTimeInMillis());
        intent.putExtra("allDay", true);
        intent.putExtra("rrule", "FREQ=YEARLY");
        intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
        intent.putExtra("title", "A Test Event from android app");
        startActivity(intent);
        }

希望它会有所帮助.....

Answer 4

从Android 4.0版开始,官方API和意图可用于与可用的日历提供程序进行交互.

Answer 5

如何以编程方式将事件添加到用户的日历？

哪个日历？

他们共有一个共同的API吗？

不,只不过是Windows日历应用程序存在"共享的API".存在一些常见的数据格式(例如,iCalendar)和因特网协议(例如,CalDAV),但是没有通用的API.某些日历应用甚至不提供API.

如果您希望集成特定日历应用程序,请与其开发人员联系并确定他们是否提供API.因此,例如,Mayra引用的Android开源项目中的日历应用程序不提供任何文档化和支持的API.谷歌甚至明确告诉开发人员不要使用 Mayra引用的教程中概述的技术.

另一个选项是您可以将事件添加到相关的Internet日历中.例如,事件添加到从Android开源项目的日历应用程序的最佳方式是通过适当的GData的API将事件添加到用户的谷歌日历.

UPDATE

Android 4.0(API Level 14)添加了一个CalendarContract ContentProvider.

Answer 6

Google日历是"原生"日历应用.据我所知,所有手机都安装了一个版本,默认SDK提供了一个版本.

您可以查看本教程以了解它.

Answer 7

试试这个 ,

   Calendar beginTime = Calendar.getInstance();
    beginTime.set(yearInt, monthInt - 1, dayInt, 7, 30);



    ContentValues l_event = new ContentValues();
    l_event.put("calendar_id", CalIds[0]);
    l_event.put("title", "event");
    l_event.put("description",  "This is test event");
    l_event.put("eventLocation", "School");
    l_event.put("dtstart", beginTime.getTimeInMillis());
    l_event.put("dtend", beginTime.getTimeInMillis());
    l_event.put("allDay", 0);
    l_event.put("rrule", "FREQ=YEARLY");
    // status: 0~ tentative; 1~ confirmed; 2~ canceled
    // l_event.put("eventStatus", 1);

    l_event.put("eventTimezone", "India");
    Uri l_eventUri;
    if (Build.VERSION.SDK_INT >= 8) {
        l_eventUri = Uri.parse("content://com.android.calendar/events");
    } else {
        l_eventUri = Uri.parse("content://calendar/events");
    }
    Uri l_uri = MainActivity.this.getContentResolver()
            .insert(l_eventUri, l_event);

Answer 8

万一有人在c#中为Xamarin需要这个:

        Intent intent = new Intent(Intent.ActionInsert);
        intent.SetData(Android.Provider.CalendarContract.Events.ContentUri);
        intent.PutExtra(Android.Provider.CalendarContract.ExtraEventBeginTime, Utils.Tools.CurrentTimeMillis(game.Date));
        intent.PutExtra(Android.Provider.CalendarContract.EventsColumns.AllDay, false);
        intent.PutExtra(Android.Provider.CalendarContract.EventsColumns.EventLocation, "Location");
        intent.PutExtra(Android.Provider.CalendarContract.EventsColumns.Description, "Description");
        intent.PutExtra(Android.Provider.CalendarContract.ExtraEventEndTime, Utils.Tools.CurrentTimeMillis(game.Date.AddHours(2)));
        intent.PutExtra(Android.Provider.CalendarContract.EventsColumns.Title, "Title");
        StartActivity(intent);

助手功能:

    private static readonly DateTime Jan1st1970 = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);

    public static long CurrentTimeMillis(DateTime date)
    {
        return (long)(date.ToUniversalTime() - Jan1st1970).TotalMilliseconds;
    }
