CalendarProvider，如何获取会议的所有者名称？

ContentResolver contentResolver = getContentResolver();
Uri uri = CalendarContract.Events.CONTENT_URI;

String[] projection = new String[]{
    CalendarContract.Events.OWNER_ACCOUNT
};

String selection = CalendarContract.Events._ID + " = ?";
String[] selectionArgs = new String[]{String.valueOf(eventId)};

Cursor cursor = contentResolver.query(uri, projection, selection, selectionArgs, null);
if (cursor != null && cursor.moveToFirst()) {
    String ownerName = cursor.getString(cursor.getColumnIndex(CalendarContract.Events.OWNER_ACCOUNT));
    cursor.close();
}
