android - 删除谷歌日历中的单次事件

Question

我想删除重复事件的单次出现。这是我的代码:

private void handleActionDelete(long event, long occurrence) {
    final ContentResolver contentResolver = getContentResolver();

    Uri.Builder eventsUriBuilder = CalendarContract.Instances.CONTENT_URI.buildUpon();
    ContentUris.appendId(eventsUriBuilder, Long.MIN_VALUE);
    ContentUris.appendId(eventsUriBuilder, Long.MAX_VALUE);
    Uri eventsUri = eventsUriBuilder.build();
    Cursor cursor;
    String[] projection;
    projection = new String[]{CalendarContract.Instances.BEGIN};
    String selection = "Instances." + CalendarContract.Instances._ID + " = ? AND " + CalendarContract.Instances
            .EVENT_ID + " = ?";
    String[] selArgs = new String[]{Long.toString(occurrence), Long.toString(event)};
    cursor = getContentResolver().query(eventsUri, projection, selection, selArgs, null);
    if (cursor == null) {
        return;
    }
    if (cursor.getCount() == 0) {
        cursor.close();
        return;
    }
    cursor.moveToFirst();

    ContentValues values = new ContentValues();
    values.put(CalendarContract.Events.ORIGINAL_INSTANCE_TIME, cursor.getLong(cursor.getColumnIndex
            (CalendarContract.Instances.BEGIN)));
    values.put(CalendarContract.Events.STATUS, CalendarContract.Events.STATUS_CANCELED);
    Uri uri = Uri.withAppendedPath(CalendarContract.Events.CONTENT_EXCEPTION_URI, String.valueOf(event));
    cursor.close();
    try {
        contentResolver.insert(uri, values);
    } catch (Exception ignored) {
    }
}

我已经在 stackoverflow 上检查了所有其他类似的问题，但我没有找到任何解决方案，也许这与我的代码有关，我希望有人可以审查它。

如果您使用 com.google.api.services.calendar.Calendar 我想您已经有了要删除的事件的 id

答案就在 documentation 中和状态(我从文档中复制了确切的 fragment ):

// Initialize Calendar service with valid OAuth credentials
Calendar service = new Calendar.Builder(httpTransport, jsonFactory, credentials)
.setApplicationName("applicationName").build();

// Delete an event
service.events().delete('primary', "eventId").execute();
