这是我的代码

     Log.i("sdfgsdf", time.toGMTString());
        String SENT = "SMS_SENT";
        Intent y=  new Intent(SENT);
        y.putExtra("number", phoneNumber);
        y.putExtra("time", time.toString());

        String DELIVERED = "SMS_DELIVERED";
        int FLAG_UPDATE_CURRENT =(0x08000000) ;
        PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
        y, FLAG_UPDATE_CURRENT);

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

        //---when the SMS has been sent---
        r=  new BroadcastReceiver(){
            @Override
             public void onReceive(Context arg0, Intent arg1) {

                switch (getResultCode())
                {

                    case Activity.RESULT_OK:

当我使用for循环发送多条短信时，我只得到了最后一条发送的短信的额外信息。如何获取所有的额外信息？

展示如何使用循环发送消息以及如何检索额外信息。 - Rasel

在上面的switch case中检索额外信息（getresultcode），并进入带有某些条件的常规循环。 - Sando

为了识别每个意图的额外信息，您必须在创建不同的意图时发送不同的请求代码。然后，在onActivityResult中，根据请求代码，您可以识别额外信息。 - Rasel

调用意图要这样做

    Bundle bundle = new Bundle();
bundle.putString("RetailerName", keyword);
bundle.putString("positon", aString);
intent.putExtras(bundle);

接收Intent并获取数据的方法如下

  Bundle bundle = this.getIntent().getExtras();
  String RetailerName = bundle.getString("retailerName");

在一个接收器中

Bundle bundle=intent.getExtras();

这应该可以获取所有的值

Bundle bundle = intent.getExtras();

for (String key : bundle.keySet()) {
    Object value = bundle.get(key);
    Log.d(TAG, String.format("%s %s (%s)", key,  
    value.toString(), value.getClass().getName()));
}
