Android SMS Delivery Intent 总是返回 -1

Question

我在 Android 上遇到了一个奇怪的问题。当我通过我的应用程序发送短信时，我想监听传递意图。这是我到目前为止所做的：

private void shootSMS(String number,long currentTime){
    SmsManager smsManager = SmsManager.getDefault();

    Intent sentIntent = new Intent(SentBroadcastReceiver.SENT_ACTION);
    Intent deliveredIntent = new Intent(DeliveredBroadcastReceiver.DELIVERED_ACTION);

    Bundle b = new Bundle();
    b.putString("num",number);
    b.putString("record_time",currentTime+"");

    sentIntent.putExtras(b);
    deliveredIntent.putExtras(b);


    PendingIntent sentPendingIntent = PendingIntent.getBroadcast(this,(int)currentTime,sentIntent,PendingIntent.FLAG_ONE_SHOT);
    PendingIntent deliveredPendingIntent = PendingIntent.getBroadcast(this,(int)currentTime,deliveredIntent,PendingIntent.FLAG_ONE_SHOT);
    smsManager.sendTextMessage(number,null,getString(R.string.app_name),sentPendingIntent,deliveredPendingIntent);

}

现在的问题是，当我的广播接收器的onReceive() 方法被调用时，我调用getResultCode() 方法，它总是返回-1！即使手机关机，也无法追踪短信是否送达！

我用 GoSMSPro 检查了号码并发送了一条失败的短信。有趣的是，当我将手机置于飞行模式时，我得到一个等于 2 的结果代码，即 SmsManager.RESULT_ERROR_RADIO_OFF

现在的问题是这里出了什么问题？

Answer 1

sendTextMessage 上的文档指出：

sentIntent：如果不为NULL，则在消息发送成功或失败时广播此PendingIntent。结果代码将为 Activity.RESULT_OK...

如果你去看看Activity.RESULT_OK，这个值是-1。

所以-1的resultCode实际上是RESULT_OK。

一般来说，最好不要查看数值，而是尝试找出它们所代表的常数。

这样做：

private void sendSms(String phonenumber, String message) {
    SmsManager manager = SmsManager.getDefault();

    PendingIntent piSend = PendingIntent.getBroadcast(this, 0, new Intent(
            SMS_SENT), 0);
    PendingIntent piDelivered = PendingIntent.getBroadcast(this, 0,
            new Intent(SMS_DELIVERED), 0);

        int length = message.length();

        if (length > MAX_SMS_MESSAGE_LENGTH) {
            ArrayList<String> messagelist = manager.divideMessage(message);

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

            int numParts = messagelist.size();
            ;
            for (int i = 0; i < numParts; i++) {
                sentIntents.add(PendingIntent.getBroadcast(this, 0,
                        new Intent(
                                SMS_SENT), 0));
                deliveryIntents.add(PendingIntent.getBroadcast(this, 0,
                        new Intent(SMS_DELIVERED), 0));
            }

            manager.sendMultipartTextMessage(phonenumber, null,
                    messagelist, sentIntents, deliveryIntents);
        } else {
            manager.sendTextMessage(phonenumber, null, message, piSend,
                    piDelivered);
        }
}  

和您的接收方：
注意使用“Activity.RESULT_OK”代替数字

private BroadcastReceiver deliveredreceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String info = "Delivery information: ";

        switch (getResultCode()) {
        case Activity.RESULT_OK:
            info += "delivered";
            break;
        case Activity.RESULT_CANCELED:
            info += "not delivered";
            break;
        }

        Toast.makeText(getBaseContext(), info, Toast.LENGTH_SHORT).show();
    }
};  

权限：

 <uses-permission android:name="android.permission.READ_SMS"></uses-permission>
 <uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
 <uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>  

此权限用于发送和接收短信。

Answer 3

试试这个方法： 要发送短信，请使用 SMS Manager 中的 sendTextMessage。

 sendTextMessage(String destinationAddress, String  scAddress, String text,PendingIntent sentIntent, PendingIntent deliveryIntent)

第一个 Pending Intent 参数 (sentIntent) 在消息发送成功或失败时触发。接收此 Intent 的广播接收器的结果代码将是以下之一。

Activity.RESULT_OK - To indicate a successful transmission.
Sms.Manager.RESULT_ERROR_GENERIC_FAILURE - To indicate a nonspecific failure
Sms.Manager.RESULT_ERROR_RADIO_OFF - To indicate the phone radio is turned off
Sms.Manager.RESULT_ERROR_NULL_PDU - To indicate a PDU failure.
SmsManager.RESULT_ERROR_NO_SERVICE - To indicate that no cellular service is currently available.

第二个 Pending 参数（deliveryIntent）只有在收件人收到您的 SMS 消息后才会触发。

发送后和传递事件通过 Toast 显示适当的消息。
