我正在编写一个需要将一些事件添加到 android 日历中的应用程序。对于插入，我只使用了以下代码：

public void onItemClick(AdapterView<?> adapter, View curview, int position, long id) {
    WhoisEntry entry = this.adapter.getItem(position);      
    String domainName = entry.getDomainName();
    Date expDate = entry.expirationDate;
    Toast.makeText(getApplicationContext(), "Domain: " + domainName, Toast.LENGTH_SHORT).show();
    Calendar cal = Calendar.getInstance();            
    Intent intent = new Intent(Intent.ACTION_EDIT);
    intent.setType("vnd.android.cursor.item/event");
    intent.putExtra("beginTime", entry.expirationDate);
    intent.putExtra("allDay", false);       
    intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
    intent.putExtra("title", "Expiration of " + entry.domainName);
    startActivity(intent);
}

现在我想知道是否可以获取与该事件关联的 id，这样在插入事件并将其 id 保存到我的应用程序后，用户可以直接从应用程序内部调用该事件。可能吗？

我提取了用于将事件存储到 android 日历中的列列表。这里的列表：

[0] "originalEvent" (id=830007842672)
[1] "availabilityStatus" (id=830007842752)
[2] "ownerAccount" (id=830007842840)
[3] "_sync_account_type" (id=830007842920)
[4] "可见性" (id=830007843008)
[5] "rrule" (id=830007843080)
[6] "lastDate" (id=830007843144)
[7] "hasAlarm" (id=830007843216)
[8] "guestsCanModify" (id=830007843288) [ 9] "guestsCanSeeGuests" (id=830007843376)
[10] "exrule" (id=830007843464)
[11] "rdate" (id=830007843528)
[12] "透明度" (id=830007843592)
[13] "timezone" ( id=830007843672）
[14]“选择”(id=830007843744)
[15] "dtstart" (id=830007843816) [16] "标题" (id=830007843888)
[17] "_sync_time" (id=830007843952)
[18] "_id" (id=830007844024) [19] "hasAttendeeData" (id=830007844088) [20] "_sync_id" (id=830007844176)
[21] "commentsUri" (id=830007844248) [22] "描述" (id=830007844328) [23] "htmlUri" (id=830007844408) [24] "_sync_account" (id=830007844480)
[25] "_sync_version" (id=830007844560)
[ 26]“hasExtendedProperties”（id=830007844640）
[27]“calendar_id”（id=830007844736）

然后，如果我想为我的活动获取新的活动 ID：

public static long getNewEventId(ContentResolver cr, Uri cal_uri){      
    Uri local_uri = cal_uri;
    if(cal_uri == null){
        local_uri = Uri.parse(calendar_uri+"events");
    } 
    Cursor cursor = cr.query(local_uri, new String [] {"MAX(_id) as max_id"}, null, null, "_id");
    cursor.moveToFirst();
    long max_val = cursor.getLong(cursor.getColumnIndex("max_id"));     
    return max_val+1;
}

对于插入事件：

public void insertDomainEntry(Date exp_date, String name, long event_id){
    SQLiteDatabase db = getWritableDatabase();
    ContentValues values = new ContentValues();
    values.put("exp_date", exp_date.getTime()/1000);
    values.put("event_id", event_id);
    values.put("domainname", name);
    db.insertOrThrow("domains_events", null, values);
}

该解决方案似乎有效，即使这可能不是一个很好的解决方案。

EDIT 02/2015 getNextEventId 的目的是为事件表创建一个新的事件条目，这里是使用此方法的代码：

@Override
    public void onItemClick(AdapterView<?> adapter, View curview, int position,
            long id) {
        WhoisEntry entry = this.adapter.getItem(position);      
        long event_id = CalendarUtils.getNewEventId(getContentResolver(), null);

        Toast.makeText(getApplicationContext(), "Domain: " + entry.getDomainName(),
                Toast.LENGTH_SHORT).show();

        Intent intent = new Intent(Intent.ACTION_EDIT);
        intent.setType("vnd.android.cursor.item/event");
        intent.putExtra("beginTime", entry.getExpiration().getTime());
        intent.putExtra("_id", event_id);
        intent.putExtra("allDay", false);       
        intent.putExtra("endTime", entry.getExpiration().getTime()+60*30);
        intent.putExtra("title", "Expiration of " + entry.getDomainName());
        startActivity(intent);

        database.insertDomainEntry(entry.getExpiration(),
                entry.getDomainName(), event_id);
    }

更新 09/2015

根据评论中的要求，我添加了如何获取日历 URI（它基本上是日历的存储位置，应用程序尝试猜测它，搜索所有已知的可能日历路径）

public static String getCalendarUriBase(Activity act) {     
    String calendarUriBase = null;
    Uri calendars = Uri.parse("content://calendar/calendars");
    Cursor managedCursor = null;

    try {
        managedCursor = act.getContentResolver().query(calendars,
                null, null, null, null);
    } catch (Exception e) {
    }

    if (managedCursor != null) {
        calendarUriBase = "content://calendar/";
    } else {
        calendars = Uri.parse("content://com.android.calendar/calendars");
        try {
            managedCursor = act.getContentResolver().query(calendars,
                    null, null, null, null);
        } catch (Exception e) {
        }
        if (managedCursor != null) {
            calendarUriBase = "content://com.android.calendar/";
        }
    }

    calendar_uri= calendarUriBase;
    return calendarUriBase;
}

插入事件后，您可以轻松获取事件 ID。

long calID = 3;
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, "Jazzercise");
values.put(Events.DESCRIPTION, "Group workout");
values.put(Events.CALENDAR_ID, calID);
values.put(Events.EVENT_TIMEZONE, "America/Los_Angeles");
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());
//
// ... do something with event ID
//
//
