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.发生的事情是,我试图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可能从目前使用的每个意图接收相同的广播？我无法弄清楚为什么会发生这种情况,或者如何阻止它.任何帮助或见解将不胜感激!

以下是导致此问题的具体方法:

 //---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(); …
