我目前正在尝试开发一个短信应用程序，并允许用户发送短信给多个人。

由于短信很长，我必须使用下面的sendMultipartTextMessage

private void sendSMS(final String phoneNumber, String message) {
    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";

    SmsManager sms = SmsManager.getDefault();
    ArrayList<String> parts = sms.divideMessage(message);
    int messageCount = parts.size();

    Log.i("Message Count", "Message Count: " + messageCount);

    ArrayList<PendingIntent> deliveryIntents = new ArrayList<PendingIntent>();
    ArrayList<PendingIntent> sentIntents = new ArrayList<PendingIntent>();

    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(SENT), 0);
    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0, new Intent(DELIVERED), 0);

    for (int j = 0; j < messageCount; j++) {
        sentIntents.add(sentPI);
        deliveryIntents.add(deliveredPI);
    }

    // ---when the SMS has been sent---
    registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode()) {
            case Activity.RESULT_OK:
                Toast.makeText(getBaseContext(), "SMS sent",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                Toast.makeText(getBaseContext(), "Generic failure",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_NO_SERVICE:
                Toast.makeText(getBaseContext(), "No service",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_NULL_PDU:
                Toast.makeText(getBaseContext(), "Null PDU",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_RADIO_OFF:
                Toast.makeText(getBaseContext(), "Radio off",
                        Toast.LENGTH_SHORT).show();
                break;
            }
        }
    }, new IntentFilter(SENT));

    // ---when the SMS has been delivered---
    registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode()) {

            case Activity.RESULT_OK:
                Toast.makeText(getBaseContext(), "SMS delivered",
                        Toast.LENGTH_SHORT).show();
                break;
            case Activity.RESULT_CANCELED:
                Toast.makeText(getBaseContext(), "SMS not delivered",
                        Toast.LENGTH_SHORT).show();
                break;
            }
        }
    }, new IntentFilter(DELIVERED));

    sms.sendMultipartTextMessage(phoneNumber, null, parts, sentIntents, deliveryIntents);
}

当我尝试在这样的循环中将消息发送给多个人时，我会遇到一个一般性错误，消息将不会被发送。我怀疑这是因为消息可能是3-4个部分，即使有3000毫秒的延迟，android系统也无法及时发送消息。

    for (int t = 0; t < array.length; t++) {
        System.out.println("temp: " + array[t].toString());
        try {
            sendSMS(array[t].toString(), message);
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

编辑:上面的代码在一个AsyncTask中，它在一个服务内部执行。

IHMO你没有使用正确的方法。我正在使用一个不同的版本，它正在工作。我试着解释一下：

您应该为所有待定意图保留一个计数器，因为如果您发送的短信有两个部分，您将收到两个RESULT_OK (或RESULT_ERROR_*)，并且只有当您收到所有部分的结果时，您才应该继续发送下一条短信。我不喜欢阻塞线程的想法...也许这就是你收到奇怪错误的原因。

我用我的方法重构了你的代码：

private int mMessageSentParts;
private int mMessageSentTotalParts;
private int mMessageSentCount;

private void startSendMessages(){

    registerBroadCastReceivers();

    mMessageSentCount = 0;
    sendSMS(array[mMessageSentCount].toString(), message);
}

private void sendNextMessage(){
    if(thereAreSmsToSend()){
        sendSMS(array[mMessageSentCount].toString(), message);
    }else{
        Toast.makeText(getBaseContext(), "All SMS have been sent",
                        Toast.LENGTH_SHORT).show();
    }
}

private boolean thereAreSmsToSend(){
    return mMessageSentCount < array.length;
}

private void sendSMS(final String phoneNumber, String message) {
    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";

    SmsManager sms = SmsManager.getDefault();
    ArrayList<String> parts = sms.divideMessage(message);
    mMessageSentTotalParts = parts.size();

    Log.i("Message Count", "Message Count: " + mMessageSentTotalParts);

    ArrayList<PendingIntent> deliveryIntents = new ArrayList<PendingIntent>();
    ArrayList<PendingIntent> sentIntents = new ArrayList<PendingIntent>();

    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(SENT), 0);
    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0, new Intent(DELIVERED), 0);

    for (int j = 0; j < mMessageSentTotalParts; j++) {
        sentIntents.add(sentPI);
        deliveryIntents.add(deliveredPI);
    }

    mMessageSentParts = 0;
    sms.sendMultipartTextMessage(phoneNumber, null, parts, sentIntents, deliveryIntents);
}

private void registerBroadCastReceivers(){

    registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode()) {
            case Activity.RESULT_OK:

                mMessageSentParts++;
                if ( mMessageSentParts == mMessageSentTotalParts ) {
                    mMessageSentCount++;
                    sendNextMessage();
                }

                Toast.makeText(getBaseContext(), "SMS sent",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                Toast.makeText(getBaseContext(), "Generic failure",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_NO_SERVICE:
                Toast.makeText(getBaseContext(), "No service",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_NULL_PDU:
                Toast.makeText(getBaseContext(), "Null PDU",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_RADIO_OFF:
                Toast.makeText(getBaseContext(), "Radio off",
                        Toast.LENGTH_SHORT).show();
                break;
            }
        }
    }, new IntentFilter(SENT));

    registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode()) {

            case Activity.RESULT_OK:
                Toast.makeText(getBaseContext(), "SMS delivered",
                        Toast.LENGTH_SHORT).show();
                break;
            case Activity.RESULT_CANCELED:
                Toast.makeText(getBaseContext(), "SMS not delivered",
                        Toast.LENGTH_SHORT).show();
                break;
            }
        }
    }, new IntentFilter(DELIVERED));

}

使用此代码时，我遇到了同样的错误"Generic failure“。但我用的是arraymMessageSentCount.toString().trim().然后它就解决了我的问题&它工作得很好。谢谢
