所以这是我的BroadcastReceiver

public class IncomingSMSListener extends BroadcastReceiver {
private static final String SMS_EXTRA_NAME = "pdus";

@Override
public void onReceive(Context context, Intent intent) {
    SmsMessage[] messages = fetchSMSMessagesFromIntent(intent);
}

private SmsMessage[] fetchSMSMessagesFromIntent(Intent intent) {
    ArrayList<SmsMessage> receivedMessages = new ArrayList<SmsMessage>();
    Object[] messages = (Object[]) intent.getExtras().get(SMS_EXTRA_NAME);
    for (Object message : messages) {
        SmsMessage finalMessage = SmsMessage
                .createFromPdu((byte[]) message);
        receivedMessages.add(finalMessage);
    }
    return receivedMessages.toArray(new SmsMessage[0]);
}

}

我能够很好地阅读传入的消息，但是假设从这里我想将消息转发到另一个电话号码并确保它被发送。我知道我可以做到SmsManager.sendTextMessage()，但我如何设置PendingIntent部件以通知是否发送了 SMS？

好的，最终找到了解决方案。由于在 BroadCastReceiver 中传递给 onReceive() 方法的上下文不允许我注册其他 BroadcastReceiver 来侦听“已发送消息”事件，因此我最终掌握了应用程序上下文并执行以下操作：

在广播接收器中：

SmsManager smsManager = SmsManager.getDefault();
    Intent intent = new Intent(SENT_SMS_FLAG);
    PendingIntent sentIntent = PendingIntent.getBroadcast(context, 0,
            intent, 0);
    SMSForwarderApp.getAppContext().registerReceiver(
            new MessageSentListener(),
            new IntentFilter(SENT_SMS_FLAG));
    smsManager.sendTextMessage("Here goes the destination of the SMS", null,
            "Here goes the content of the SMS", sentIntent, null);

SENT_SMS_FLAG 只是一个静态字符串，用于唯一标识我刚刚创建的意图。我的 MessageSentListener 看起来像这样：

public class MessageSentListener extends BroadcastReceiver{

@Override
public void onReceive(Context context, Intent intent) {
    int resultCode = this.getResultCode();
    boolean successfullySent = resultCode == Activity.RESULT_OK;
    //That boolean up there indicates the status of the message
    SMSForwarderApp.getAppContext().unregisterReceiver(this);
            //Notice how I get the app context again here and unregister this broadcast
            //receiver to clear it from the system since it won't be used again
}

}
