如果消息已成功传递或发送，Android 短信会收到响应错误/通知

Question

How can i get the error when sending message and the response when the message has been successfully sent?

这是我的代码:

try {    
   String message = "Hello World! Now we are going to demonstrate " + 
      "how to send a \n message with more than \n 160 characters from your Android application.";
   SmsManager smsManager = SmsManager.getDefault();
   ArrayList<String> parts = smsManager.divideMessage(message ); 
   smsManager.sendMultipartTextMessage(phoneNumber, null, parts, null, null);
} catch (Exception e) {
   //HOW CAN I GET THE SMS RESPONES HERE
   Toast.makeText(context, "SMS faild!",Toast.LENGTH_LONG).show();
   e.printStackTrace();
}

你不能catch发送或交付成功/失败，因为它不是 Exception ，也不是任何其他类型的 Throwable .

您将需要创建 PendingIntent s 用于已发送 和已发送 操作，并在用于发送 SMS 的方法中传递它们。以下是可用于单部分或多部分消息的示例。

public static final String ACTION_SMS_SENT = "com.mycompany.myapp.SMS_SENT";
public static final String ACTION_SMS_DELIVERED = "com.mycompany.myapp.SMS_DELIVERED";

private void sendSMS(String number, String message) {
    final SmsManager sm = SmsManager.getDefault();        
    final ArrayList<String> parts = sm.divideMessage(message);
    final int ct = parts.size();

    final ArrayList<PendingIntent> sentPis = new ArrayList<PendingIntent>(ct);      
    final ArrayList<PendingIntent> delPis = new ArrayList<PendingIntent>(ct);       

    for (int i = 0; i < ct; i++) {
        final PendingIntent piSent =
            PendingIntent.getBroadcast(this,
                                       i,
                                       new Intent(ACTION_SMS_SENT),
                                       0);
        final PendingIntent piDel =
            PendingIntent.getBroadcast(this,
                                       i,
                                       new Intent(ACTION_SMS_DELIVERED),
                                       0);

        sentPis.add(piSent);
        delPis.add(piDel);
    }

    sm.sendMultipartTextMessage(number, null, parts, sentPis, delPis);
}

您需要注册一个 BroadcastReceiver得到结果。一个基本的接收器示例:

public class SmsResultReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();

        if (action.equals(ACTION_SMS_SENT)) {
            switch (getResultCode()) {
                case -1: //Activity.RESULT_OK
                    break;

                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    break;

                case SmsManager.RESULT_ERROR_NULL_PDU:
                    break;

                case SmsManager.RESULT_ERROR_RADIO_OFF:
                    break;

                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    break;

                default:
            }
        }
        else if (action.equals(ACTION_SMS_DELIVERED)) {
            switch (getResultCode()) {
                case -1: //Activity.RESULT_OK
                    break;

                case 0: //Activity.RESULT_CANCELED
                    break;

                default:
            }
        }
    }
}

请注意，每个 Receiver 将针对每个消息部分运行一次。我还要提一下，并非所有承运商都提供送货报告，因此无法保证送达 PendingIntent s 将永远开火。

可以使用 Context#registerReceiver() 动态注册此 Receiver 的实例方法，或者可以使用 <receiver> 在 list 中注册 Receiver 类元素，以及适当的 <intent-filter>
