我在上面的链接中使用了我自己的应用程序中的示例代码来发送短信，但是在检查我的消息的发送状态时遇到了问题。结果是，我尝试发送的每条消息都会弹出 toast 消息。所以基本上，假设我已经发送了 3 条消息。当我发送第 4 条消息时，toast 消息将弹出 4 次。似乎 BroadcastReceiver 正在从目前使用的每个 Intent 接收相同的广播？我无法弄清楚为什么会这样，或者如何阻止它。任何帮助或见解将不胜感激!

下面是导致这个的具体方法:

 //---sends an SMS message to another device---
private void sendSMS(String phoneNumber, String message)
{        
    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";

    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
        new Intent(SENT), 0);

    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
        new Intent(DELIVERED), 0);

    //---when the SMS has been sent---
    registerReceiver(new BroadcastReceiver(){
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode())
            {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), "SMS sent", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    Toast.makeText(getBaseContext(), "Generic failure", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    Toast.makeText(getBaseContext(), "No service", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_NULL_PDU:
                    Toast.makeText(getBaseContext(), "Null PDU", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_RADIO_OFF:
                    Toast.makeText(getBaseContext(), "Radio off", 
                            Toast.LENGTH_SHORT).show();
                    break;
            }
        }
    }, new IntentFilter(SENT));

    //---when the SMS has been delivered---
    registerReceiver(new BroadcastReceiver(){
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode())
            {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), "SMS delivered", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case Activity.RESULT_CANCELED:
                    Toast.makeText(getBaseContext(), "SMS not delivered", 
                            Toast.LENGTH_SHORT).show();
                    break;                        
            }
        }
    }, new IntentFilter(DELIVERED));        

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

最佳答案

首先，每次调用 sendSMS 时都会有一个 new BroadcastReceiver(){，因此它们会堆积起来，每次调用 sendSMS。您可以在每个 BroadcastReceiver 的底部添加 unregister(this); 但最好是将 Broadcast 接收器移出此函数。您可以在 onResume() 中创建+注册，并在 onPause() 中取消注册。

其次，读这个link

如果您想随 pendingIntent 一起发送数据，您需要帮助 Android 更好地区分您的待定 Intent ......
例如

 PendingIntent deliveredPI = PendingIntent.getBroadcast(this, uniqueIdPerSMS++,
    new Intent(DELIVERED), PendingIntent.FLAG_CANCEL_CURRENT);
