Question

这是我的代码。它将允许我检索我从Android手机发送的所有消息。我只想检索未读消息。

提前致谢。

private String load_sent_sms() {
        // TODO Auto-generated method stub
        Uri uriSms = Uri.parse("content://sms/sent");
        Cursor cursor = getContentResolver().query(uriSms,
                new String[] { "_id", "address", "date", "body" }, null, null,
                null);
        String sms = "";
        cursor.moveToFirst();
        while (cursor.moveToNext()) {
            String address = cursor.getString(1);
            String body = cursor.getString(3);
            sms += "Contact Name: " + address + "\nMessage: " + body + "\n";

        }
        return sms;

    }
