Android 从pdus对象获取messageID

我的应用程序收听新的短信。现在，当我收到一条新的短信时，我会创建一条短信。为了对此进行进一步的操作，我需要消息的Id。因此，我对内容解析器进行如下查询：

 final Bundle bundle = intent.getExtras();

    try {

        if (bundle != null) {
            //get the protocol discription unit ( SMSs)
            final Object[] pdusObj = (Object[]) bundle.get("pdus");

            for (int i = 0; i < pdusObj.length; i++) {

                SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                String phoneNumber = currentMessage.getDisplayOriginatingAddress();
                String message = currentMessage.getDisplayMessageBody();
                long time_rcv = currentMessage.getTimestampMillis();

                String [] relevantColumns = {"_id", "address", "body", "date_sent"};
                Cursor cursor = context.getContentResolver().query(
                        Uri.parse("content://sms/inbox"),
                        relevantColumns,
                        "address = '" + phoneNumber + "' AND body = '" + message
                                + "' AND date_sent = '" + time_rcv + "'",
                        null,
                        null);

                if (cursor != null && cursor.moveToFirst()) {
                    int id = Integer.valueOf(cursor.getString(0));
                    Log.d(TAG,"ID SMS: " + id);
                }
                else
                    Log.e(TAG,"Failed to find ID");

                Log.i(TAG, "FROM: " + phoneNumber + "; MSG: " + message);

                Toast.makeText(context, "From: " + phoneNumber + ", MSG: " + message, Toast.LENGTH_LONG).show();
            }
        }
    } catch (Exception e) {
        Log.e(TAG, "Exception receiver" + e);

    }

不管发生什么，它都找不到信息

我的代码是正确的。唯一的问题是，在我的receivebroadcast完成之前，短信不在短信/收件箱中。因此，下次您运行代码并手动填充字段时，代码会找到sms并为您提供id
