Question

我在Android上面临一个奇怪的问题。当我通过我的应用程序发送短信时，我想听取发送意图。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，当调用广播接收器的onReceive()方法时，我调用getResultCode()方法，它总是返回-1！即使手机关闭，也无法跟踪短信是否已发送！

我使用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，我得到的结果代码等于2 SmsManager.RESULT_ERROR_RADIO_OFF

现在问题是这里有什么不对？

Answer 1

sendTextMessage州的文档：

sentIntent：如果不为NULL，则在成功发送消息或失败时广播此PendingIntent。结果代码为Activity.RESULT_OK ...

如果你去查看Activity.RESULT_OK，则值为-1。

所以resultCode为-1实际上是RESULT_OK。

一般来说，最好不要查看数值，而是试图找出它们代表的常数。

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);
        }
}

和你的接收者：
注意使用＆＃34; Activity.RESULT_OK＆＃34;而不是数字

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();
    }
};

许可：

 <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。

尝试此方法：要发送短信，请使用SMS Manager中的sendTextMessage。

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

当邮件成功发送或失败时，将触发第一个Pending Intent参数（sentIntent）。接收此Intent的Broadcast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.

仅在收件人收到您的短信后才会触发第二个待处理参数（deliveryIntent）。

发送和发送事件后，通过Toast显示相应的消息。
