如何在 android 4 中無意圖地將日歷事件添加到默認日歷中？

Question

我想在 android 4+ 中以編程方式（直接）添加日歷事件。 這是否可以在模擬器上進行測試？ 我沒有安卓手機。 一些示例代碼將不勝感激。 我閱讀了 android 開發人員的日歷提供程序，但我很困惑。 如何將事件添加到用戶的默認日歷？ 我不需要同步。

編輯：我不想啟動添加 Intent 的事件。 相反，我想完全從代碼中添加它們，而不是啟動另一個活動。 我需要能夠在模擬器上測試事件將被添加到設備默認用戶的主日歷中。 如何設置模擬器以查看用戶的默認日歷？

Answer 1

這是我最終做到的一個工作示例：

ContentResolver cr = ctx.getContentResolver();
ContentValues values = new ContentValues();

values.put(CalendarContract.Events.DTSTART, dtstart);
values.put(CalendarContract.Events.TITLE, title);
values.put(CalendarContract.Events.DESCRIPTION, comment);

TimeZone timeZone = TimeZone.getDefault();
values.put(CalendarContract.Events.EVENT_TIMEZONE, timeZone.getID());

// Default calendar
values.put(CalendarContract.Events.CALENDAR_ID, 1);

values.put(CalendarContract.Events.RRULE, "FREQ=DAILY;UNTIL="
        + dtUntill);
// Set Period for 1 Hour
values.put(CalendarContract.Events.DURATION, "+P1H");

values.put(CalendarContract.Events.HAS_ALARM, 1);

// Insert event to calendar
Uri uri = cr.insert(CalendarContract.Events.CONTENT_URI, values);

dtuntil在哪里

SimpleDateFormat yyyyMMdd = new SimpleDateFormat("yyyyMMdd");
Calendar dt = Calendar.getInstance();

// Where untilDate is a date instance of your choice, for example 30/01/2012
dt.setTime(untilDate);

// If you want the event until 30/01/2012, you must add one day from our day because UNTIL in RRule sets events before the last day
dt.add(Calendar.DATE, 1);
String dtUntill = yyyyMMdd.format(dt.getTime());

參考： Recurrence Rule

Answer 2

我相信您要查找的部分是使用意圖插入事件 。 在本節中，它描述了如何為要添加的事件創建意圖，然后模擬器上的默認日歷程序將響應並添加它。 您可能必須設置虛擬配置文件，以便在您確實希望看到它收到正確信息時啟動日歷程序。

來自Android Dev Site的代碼：

Calendar beginTime = Calendar.getInstance();
beginTime.set(2012, 0, 19, 7, 30);
Calendar endTime = Calendar.getInstance();
endTime.set(2012, 0, 19, 8, 30);
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);

使用此代碼，您可以以編程方式將事件添加到設備日歷。 我在Marshmallow測試過，它對我來說很好。

private void addToDeviceCalendar(String startDate,String endDate, String title,String description, String location) {

        String stDate = startDate;
        String enDate = endDate;

        GregorianCalendar calDate = new GregorianCalendar();
        //GregorianCalendar calEndDate = new GregorianCalendar();

        SimpleDateFormat originalFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm");
        SimpleDateFormat targetFormat = new SimpleDateFormat("yyyy,MM,dd,HH,mm");
        Date date,edate;
        try {
            date = originalFormat.parse(startDate);
            stDate=targetFormat.format(date);

        } catch (ParseException ex) {}

        long startMillis = 0;
        long endMillis = 0;
        String dates[] = stDate.split(",");

        SD_YeaR = dates[0];
        SD_MontH = dates[1];
        SD_DaY = dates[2];
        SD_HouR = dates[3];
        SD_MinutE = dates[4];


        /*Log.e("YeaR ", SD_YeaR);
        Log.e("MontH ",SD_MontH );
        Log.e("DaY ", SD_DaY);
        Log.e(" HouR", SD_HouR);
        Log.e("MinutE ", SD_MinutE);*/

        calDate.set(Integer.parseInt(SD_YeaR), Integer.parseInt(SD_MontH)-1, Integer.parseInt(SD_DaY), Integer.parseInt(SD_HouR), Integer.parseInt(SD_MinutE));
        startMillis = calDate.getTimeInMillis();
/*
        try {
            edate = originalFormat.parse(endDate);
            enDate=targetFormat.format(edate);

        } catch (ParseException ex) {}


        String end_dates[] = endDate.split(",");

        String ED_YeaR = end_dates[0];
        String ED_MontH = end_dates[1];
        String ED_DaY = end_dates[2];

        String ED_HouR = end_dates[3];
        String ED_MinutE = end_dates[4];


        calEndDate.set(Integer.parseInt(ED_YeaR), Integer.parseInt(ED_MontH)-1, Integer.parseInt(ED_DaY), Integer.parseInt(ED_HouR), Integer.parseInt(ED_MinutE));
        endMillis = calEndDate.getTimeInMillis();*/

        try {
            ContentResolver cr = getActivity().getContentResolver();
            ContentValues values = new ContentValues();
            values.put(CalendarContract.Events.DTSTART, startMillis);
            values.put(CalendarContract.Events.DTEND, calDate.getTimeInMillis() + 60 * 60 * 1000);
            values.put(CalendarContract.Events.TITLE, title);
            values.put(CalendarContract.Events.DESCRIPTION, description);
            values.put(CalendarContract.Events.EVENT_LOCATION,location);
            values.put(CalendarContract.Events.HAS_ALARM,1);
            values.put(CalendarContract.Events.CALENDAR_ID, 1);
            values.put(CalendarContract.Events.EVENT_TIMEZONE, Calendar.getInstance()
                    .getTimeZone().getID());
            System.out.println(Calendar.getInstance().getTimeZone().getID());
            if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.WRITE_CALENDAR) != PackageManager.PERMISSION_GRANTED) {

                return;
            }
            Uri uri = cr.insert(CalendarContract.Events.CONTENT_URI, values);

            long eventId = Long.parseLong(uri.getLastPathSegment());
            Log.d("Ketan_Event_Id", String.valueOf(eventId));

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Answer 4

別忘了向Manifest添加權限

<uses-permission android:name="android.permission.READ_CALENDAR"/>
<uses-permission android:name="android.permission.WRITE_CALENDAR"/>

代碼來自： - > Android Dev Site

long calID = 3; // Make sure to which calender you want to add event 
long startMillis = 0;
long endMillis = 0;
Calendar beginTime = Calendar.getInstance();
beginTime.set(2012, 9, 14, 7, 30);
startMillis = beginTime.getTimeInMillis();
Calendar endTime = Calendar.getInstance();
endTime.set(2012, 9, 14, 8, 45);
endMillis = endTime.getTimeInMillis();


ContentResolver cr = getContentResolver();
ContentValues values = new ContentValues();
values.put(Events.DTSTART, startMillis);
values.put(Events.DTEND, endMillis);
values.put(Events.TITLE, "Hackathon");
values.put(Events.DESCRIPTION, "do some code");
values.put(Events.CALENDAR_ID, calID);
values.put(Events.EVENT_TIMEZONE, TimeZone.getDefault().getID());
Uri uri = cr.insert(Events.CONTENT_URI, values);

// get the event ID that is the last element in the Uri
long eventID = Long.parseLong(uri.getLastPathSegment());

Answer 5

同意以上所有答案，但導入是日歷ID。 你不能使用1作為三星手機使用1作為他們的日歷（S Planner）。所以日歷ID是您想要活動的電子郵件的ID。 您可以通過以下代碼獲取特定事件的日歷ID

int calenderId=-1;
        String calenderEmaillAddress="xxx@gmail.com";
        String[] projection = new String[]{
                CalendarContract.Calendars._ID,
                CalendarContract.Calendars.ACCOUNT_NAME};
        ContentResolver cr = activity.getContentResolver();
        Cursor cursor = cr.query(Uri.parse("content://com.android.calendar/calendars"), projection,
                CalendarContract.Calendars.ACCOUNT_NAME + "=? and (" +
                        CalendarContract.Calendars.NAME + "=? or " +
                        CalendarContract.Calendars.CALENDAR_DISPLAY_NAME + "=?)",
                new String[]{calenderEmaillAddress, calenderEmaillAddress,
                        calenderEmaillAddress}, null);

        if (cursor.moveToFirst()) {

            if (cursor.getString(1).equals(calenderEmaillAddress))
                 calenderId=cursor.getInt(0); //youre calender id to be insered in above 2 answer


        }

Answer 6

以下是詢問用戶必須添加事件的日歷的方法。 正如我的要求是這樣，並沒有在一個地方找到解決方案。 我已經總結並提出了這個解決方案，希望它可以幫助某人:)

final ContentResolver cr = this.getContentResolver();
        Cursor cursor ;
        if (Integer.parseInt(Build.VERSION.SDK) >= 8 )
            cursor = cr.query(Uri.parse("content://com.android.calendar/calendars"), new String[]{ "_id", "calendar_displayName" }, null, null, null);
        else
            cursor = cr.query(Uri.parse("content://calendar/calendars"), new String[]{ "_id", "displayname" }, null, null, null);
        if (cursor != null && cursor.moveToFirst() ) {
            final String[] calNames = new String[cursor.getCount()];
            final int[] calIds = new int[cursor.getCount()];
            for (int i = 0; i < calNames.length; i++) {
                calIds[i] = cursor.getInt(0);
                calNames[i] = cursor.getString(1);
                cursor.moveToNext();
            }

            SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            final long startDate = sdf.parse(slotData.getSlot_date() + " " + slotData.getSlot_from()).getTime();
            final long endDate = sdf.parse(slotData.getSlot_date() + " " + slotData.getSlot_to()).getTime();

            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("Select any one");
            builder.setSingleChoiceItems(calNames, -1, new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    ContentValues cv = new ContentValues();
                    cv.put("calendar_id", calIds[which]);
                    cv.put("title", title);
                    cv.put("dtstart", startDate);
                    cv.put("hasAlarm", 1);
                    cv.put("dtend", endDate);
                    cv.put("eventTimezone", TimeZone.getDefault().getID());

                    Uri newEvent ;
                    if (Integer.parseInt(Build.VERSION.SDK) >= 8 )
                        newEvent = cr.insert(Uri.parse("content://com.android.calendar/events"), cv);
                    else
                        newEvent = cr.insert(Uri.parse("content://calendar/events"), cv);

                    if (newEvent != null) {
                        long id = Long.parseLong( newEvent.getLastPathSegment() );
                        ContentValues values = new ContentValues();
                        values.put( "event_id", id );
                        values.put( "method", 1 );
                        values.put( "minutes", 15 ); // 15 minutes
                        if (Integer.parseInt(Build.VERSION.SDK) >= 8 )
                            cr.insert( Uri.parse( "content://com.android.calendar/reminders" ), values );
                        else
                            cr.insert( Uri.parse( "content://calendar/reminders" ), values );

                    }
                    dialog.cancel();
                }

            });

            builder.create().show();
        }
        if (cursor != null) {
            cursor.close();
        }

Answer 7

在閱讀了幾篇文章並嘗試了幾次之后。 我終於發現這種方法在 Android 8 和 10 上運行良好。

我的代碼：

    public void addEventToCalendar() {
    Context myContext = getContext();
    String[] projection = {"_id", "calendar_displayName"};
    Cursor calCursor = myContext.getContentResolver().query(CalendarContract.Calendars.CONTENT_URI, projection, CalendarContract.Calendars.VISIBLE + " = 1 AND "  + CalendarContract.Calendars.IS_PRIMARY + "=1", null, CalendarContract.Calendars._ID + " ASC");
    if(calCursor.getCount() <= 0){
        calCursor = myContext.getContentResolver().query(CalendarContract.Calendars.CONTENT_URI, projection, CalendarContract.Calendars.VISIBLE + " = 1", null, CalendarContract.Calendars._ID + " ASC");
    }

    while (calCursor.moveToNext()) {
        long id = calCursor.getLong(calCursor.getColumnIndexOrThrow(CalendarContract.Calendars._ID));
        long startMillis;
        long endMillis;
        Calendar beginTime = Calendar.getInstance();
        beginTime.set(2021, 9, 22, 15, 30);
        startMillis = beginTime.getTimeInMillis();
        Calendar endTime = Calendar.getInstance();
        endTime.set(2021, 9, 22, 16, 45);
        endMillis = endTime.getTimeInMillis();

        ContentResolver cr = Objects.requireNonNull(getActivity()).getContentResolver();
        ContentValues values = new ContentValues();
        values.put(CalendarContract.Events.DTSTART, startMillis);
        values.put(CalendarContract.Events.DTEND, endMillis);
        values.put(CalendarContract.Events.TITLE, "My event");
        values.put(CalendarContract.Events.DESCRIPTION, "Nice description");
        values.put(CalendarContract.Events.CALENDAR_ID, id);
        Log.i("ID","my Id"+ id);
        values.put(CalendarContract.Events.EVENT_TIMEZONE, TimeZone.getDefault().getID());
        Uri uri = cr.insert(CalendarContract.Events.CONTENT_URI, values);

        long eventID = Long.parseLong(uri.getLastPathSegment());
    }

}

我能夠在不同的手機上進行測試，插入是在谷歌日歷和基本的安卓日歷上完成的。

通常，此方法可確保將事件插入設備上的所有可用日歷。 我無法測試它，但我寄予厚望。
