我如何发送短信从一个BroadcastReceiver，并检查其状态？ [英] How can I send an SMS from a BroadcastReceiver and check its status?

问题描述

所以这是我的的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]);
}

}

我能够读取传入的消息就好了，而是让我们说，在这里，我想将消息转发到另一个电话号码，并确保它得到了发送。我知道我可以做 SmsManager.sendTextMessage（）但如何建立 PendingIntent 部分是否被通报短信被罚与否？

I'm being able to read the incoming message just fine and all, but let's say from here I want to forward the message to another phone number and make sure it got sent. I know I can do SmsManager.sendTextMessage() but how do I set up the PendingIntent part to be notified whether the SMS got sent or not?

推荐答案

确定，最终找到最终的解决方案。由于传递给在的BroadcastReceiver中的onReceive（）方法的情况下并没有让我注册其他BroadcastReceivers听的消息派事件，我最终得到的应用程序上下文的抓地力和做什么如下：

OK, ended up finding the solution in the end. Since the context passed in to the onReceive() method in the BroadCastReceiver doesn't let me register other BroadcastReceivers to listen for the "message sent" event, I ended up getting a grip of the app context and doing what follows:

在BroadcastReceiver的：

In the BroadcastReceiver:

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只是一个静态的字符串，它唯一标识我刚才提出的意图。我MessageSentListener看起来是这样的：

SENT_SMS_FLAG is simply a static string that uniquely identifies the intent I just made. My MessageSentListener looks like this:

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
}

}
