Android - 发送的文本总是返回 RESULT OK

Question

我的一些代码有问题，需要一些帮助。我这里的代码发送了一个文本...但我遇到的问题是接收文本的代码总是返回 RESULT_OK...我可以关闭电话/尝试一个我知道不是真实的号码并且它将永远返回 RESULT_OK... 任何人都可以在正确的方向上帮助我，有什么明显的错误吗？我使用了错误的代码吗？任何帮助都会很棒!谢谢

收到短信时的代码:

Blockquote

Globals.GlobalContext.registerReceiver(new BroadcastReceiver()
    {
        @Override
        public void onReceive(Context context, Intent arg1)
        {
            switch (getResultCode())
            {
            case Activity.RESULT_OK:
                Globals.UpdateStatus("Message was delivered");
                Bundle extras = arg1.getExtras();
                if (extras != null)
                {
                    arg1.getStringExtra("smsNumber");
                    String number = arg1.getStringExtra("smsNumber");
                    Globals.UpdateStatus("Delivered to :" + number);
                    arg1 = null;
                }
                else
                {
                    Globals.UpdateStatus("Sent to a number that I don't know :(");
                }

                break;
            case Activity.RESULT_CANCELED:
                Globals.UpdateStatus("Message was NOT delivered");
                break;
            }

        }

    }, new IntentFilter(DELIVERED));

发送短信的代码:

public void SendTextMessageDelivery(String number, String Message)
{
    if ((CheckValidPhoneNumber(number)) && (Message.length() != 0))
    {
        if (!CheckSMSManager())
        {
            StartSMSManager(true);
        }



        //sent
        PendingIntent sentPI = PendingIntent.getBroadcast(Globals.GlobalContext, 0, new Intent(SENT), 0);
        ArrayList<PendingIntent> sentIntents = new ArrayList<PendingIntent>();
        sentIntents.add(sentPI);

        //delivered
        Intent DeliveredIntent = new Intent(DELIVERED);
        DeliveredIntent.putExtra("smsNumber", number);

        PendingIntent DeliveredPI = PendingIntent.getBroadcast(Globals.GlobalContext, 0, DeliveredIntent, PendingIntent.FLAG_UPDATE_CURRENT );
        ArrayList<PendingIntent> DeliveredIntents = new ArrayList<PendingIntent>();
        DeliveredIntents.add(DeliveredPI);

        ArrayList<String> mSMSMessage = smsManager.divideMessage(Message);
        for (int i = 0; i < mSMSMessage.size(); i++)
        {

        }
        smsManager.sendMultipartTextMessage(number, null, mSMSMessage, sentIntents, DeliveredIntents);
    }
    else
    {
        if (Message.length() != 0)
        {
            Globals.UpdateStatus("Message was not long enough!");
        }
        else
        {
            Globals.UpdateStatus("Failed to Validate Mobile Number");
        }
    }
}

有几个原因可能导致您得到不正确的结果。首先也是最重要的:检查 getResultCode() 不是确定交付成功或失败的正确方法。尽管许多示例使用此方法，但真正的结果将在从服务中心返回并传递到接收器的 SMS 状态消息上。

交给您的接收器的 Intent 将附加一个单独的 PDU 作为附加。必须从中创建一个 SmsMessage，并且从其 getStatus() 方法返回的值将是实际结果。例如，您的交付结果 Receiver 可能类似于以下内容(尽管最好将额外的部分交给 Service 进行处理)。

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Build;
import android.provider.Telephony;
import android.telephony.SmsMessage;

public class DeliveryResultReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        SmsMessage sms = null;

        byte[] pdu = intent.getByteArrayExtra("pdu");
        String format = intent.getStringExtra("format");

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && format != null) {
            sms = SmsMessage.createFromPdu(pdu, format);
        }
        else {
            sms = SmsMessage.createFromPdu(pdu);
        }

        int statusCode = sms.getStatus();
        String status = translateDeliveryStatus(statusCode);
        ...
    }

    String translateDeliveryStatus(int statusCode) {
        switch (statusCode) {
            case Telephony.Sms.STATUS_COMPLETE:
                return "Sms.STATUS_COMPLETE";
            case Telephony.Sms.STATUS_FAILED:
                return "Sms.STATUS_FAILED";
            case Telephony.Sms.STATUS_PENDING:
                return "Sms.STATUS_PENDING";
            case Telephony.Sms.STATUS_NONE:
                return "Sms.STATUS_NONE";
            default:
                return "Unknown status code";
        }
    }
}

如果实现此操作后，您仍然收到误报，则可能是由于您的承运人如何定义“已送达”。交付可能并不意味着交付到目标设备。确切的行为因提供商而异，甚至在服务中心级别也是如此。以下可能不是来自 best source , 但正如我所看到的那样简洁:

Some providers allow users to request delivery reports, either via the SMS settings of most modern phones, or by prefixing each message with *0# or *N#. However, the exact meaning of confirmations varies from reaching the network, to being queued for sending, to being sent, to receiving a confirmation of receipt from the target device, and users are often not informed of the specific type of success being reported.
