Android SendMultipartTextMessage 带有未决意图，所有部分的额外值都相同

Question

我使用 Xamarin Studio 和 SMS.Telephony.SmsManager Android 库成功通过 Android 发送多部分（串联）消息。

要发送消息，我正在执行以下操作：

var longMessage = "This is a cØncatenated message sent to you through an android.   This should appear as a single message.  Hopefully it's as easy as that.  It even has a function to break the message up. It probably took me longer to install Xamarin then it did to write the code and send the actual message";
var smsMgr = Android.Telephony.SmsManager.Default;
System.Collections.Generic.IList<string> parts = smsMgr.DivideMessage(longMessage);
IList<PendingIntent> pendingIntents = new List<PendingIntent>(parts.Count);
for (int i = 0; i < parts.Count; i++)
{
  var intent = new Intent(DeliveryIntentAction);
  intent.PutExtra("MessagePartText", parts[i]);
  intent.PutExtra("MessagePartId", i.ToString());
  PendingIntent pi = PendingIntent.GetBroadcast(this, 0, intent, 0);
  pendingIntents.Add(pi);
}

smsMgr.SendMultipartTextMessage("xxx",null, parts, pendingIntents, null); 

然后我有一个用于待处理意图的接收器，如下所示：

[BroadcastReceiver(Enabled = true)] //(Exported = true, Permission = "//receiver/@android:android.permission.SEND_SMS")]
[IntentFilter(new[] { DeliveryIntentAction }, Priority = int.MaxValue)]
public class SMSSentReceiver : BroadcastReceiver
{
  public override void OnReceive(Context context, Intent intent)
  {
    if (intent.GetStringExtra ("MessagePartId") != null)
      lbl.Text += " Sent Response " + intent.GetStringExtra ("MessagePartId") + System.Environment.NewLine;
...

但是，每次调用 OnRecieve 时，intent.GetStringExtra("MessagePartId") 的值为“0”，并且 MessagePartText 是第一个部分，而不是属于发送的消息部分的部分编号/文本。

有人能明白为什么会出现这种情况吗？

谢谢你

使用 PendingIntent pi = PendingIntent.GetBroadcast(this, 0, 意图, 0); 尝试覆盖现有的pendingIntent。

要创建一个新意图并让它等待，我必须更改 GetBroadcast 的 requestCode 参数。

PendingIntent pi = PendingIntent.GetBroadcast(this, i, 意图, 0);

谢谢
