对系统对话框 SmsManager 作出反应

Question

我的应用程序发送这样的文本：

SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(NUMBER, null, "sms message", null, null);

在向用户发送之前，系统会显示一个他必须确认的系统对话框。

"App would like to send a message to 000"

我想对用户取消该对话框的情况做出反应。有办法吗？

找到了解决我的问题的方法。如果用户取消对话框，"sent" PendingIntent 将失败。

String SENT = "sent";
    Intent sentIntent = new Intent(SENT);
    PendingIntent sentPI = PendingIntent.getBroadcast(
            getApplicationContext(), 0, sentIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);

    registerReceiver(new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            String result = "";

            switch (getResultCode()) {
                case Activity.RESULT_OK:
                    result = "Transmission successful";
                    break;
                case 5: // SmsManager.RESULT_ERROR_LIMIT_EXCEEDED
                    // The static variable is hidden.
                    // The user denied sending the sms
                    break;
                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    result = "Transmission failed";
                    break;
                case SmsManager.RESULT_ERROR_RADIO_OFF:
                    result = "Radio off";
                    break;
                case SmsManager.RESULT_ERROR_NULL_PDU:
                    result = "No PDU defined";
                    break;
                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    result = "No service";
                    break;
            }
            Log.i("debug", result);
        }

    }, new IntentFilter(SENT));

    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(SMS_NUMBER, null, MESSAGE, sentPI, null);
