android - 检查是否确实发送了 SMS

Question

在我的 SMS 应用程序中，我使用SmsManager. 之后，我想显示一个 Toast 说法"Message sent"或"Message not sent". 如何检查消息是否实际发送？可能是没有连接的问题？还是没有 SIM 卡？我怎么能检测到这些？

Answer 1

您可以为交付和发送设置侦听器，我的方法是

PendingIntent sentPI = PendingIntent.getBroadcast(mContext, 0, new Intent(SENT), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(mContext, 0,new Intent(DELIVERED), 0);
String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";


// ---when the SMS has been sent---
        mContext.registerReceiver(
                new BroadcastReceiver()
                {    
                    @Override
                    public void onReceive(Context arg0,Intent arg1)
                    {
                        switch(getResultCode())
                        {
                    case Activity.RESULT_OK:

                            break;
                    case SmsManager.RESULT_ERROR_GENERIC_FAILURE:

                            break;
                    case SmsManager.RESULT_ERROR_NO_SERVICE:
                            break;
                    case SmsManager.RESULT_ERROR_NULL_PDU:
                            break;
                    case SmsManager.RESULT_ERROR_RADIO_OFF:
                            break;
                        }
                    }
                }, new IntentFilter(SENT));
        // ---when the SMS has been delivered---
        mContext.registerReceiver(
                new BroadcastReceiver()
                {

                    @Override
                    public void onReceive(Context arg0,Intent arg1)
                    {
                        switch(getResultCode())
                        {
                        case Activity.RESULT_OK:
                            break;
                        case Activity.RESULT_CANCELED:
                            break;
                        }
                    }
                }, new IntentFilter(DELIVERED));


SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null,message,sentPI, deliveredPI);

试试下面的片段。这里的异常表示所有可能的失败情况

片段

try {
      SmsManager smsManager = SmsManager.getDefault();
      smsManager.sendTextMessage(number, null, sms, null, null);
      Toast.makeText(getApplicationContext(), "SMS Sent!",
                            Toast.LENGTH_LONG).show();
 } catch (Exception e) {
        Toast.makeText(getApplicationContext(), "SMS failed, please try again later!",
               Toast.LENGTH_LONG).show();
         e.printStackTrace();
}
