在服务中，当在广播接收器中收听传送报告的循环中发送微笑时，如何区分发送的每个短信的传送报告？ 这类似于： How to get Delivery Report of each SMS sent in loop android?
除了我认为他在一个活动中使用它，我在一个getIntent（）无效的服务中使用它。

答案 0 :(得分：11)
您可以在Intent中添加额外的消息编号，如下所示：
delivered.putExtra("MsgNum", serialnum);
你尝试像这样提取它：
USS.execute(intent.getStringExtra("Msgnum"));
在putExtra()中你有大写“N”，在getStringExtra()中你使用小写“n”。
这就是总是为这样的东西使用常量的原因。它可以防止你花费数小时试图查找由印刷错误引起的错误。
试试这个：
public static final String EXTRA_MSGNUM = "MsgNum";
然后使用：
delivered.putExtra(EXTRA_MSGNUM, serialnum);
和
USS.execute(intent.getStringExtra(EXTRA_MSGNUM));
编辑：根据OP的评论添加有关生成不同PendingIntent的内容
我对错字很不好，感觉就像是一只羊，我测试了它，它 现在不给出空值，而是给出了序列号 如果我发送17，则在循环中为所有消息发送的第一条消息 20 24 21 25 27，所有交付报告只给我17个
您的问题是PendingIntent的工作方式。系统管理PendingIntent s池。代码执行时：
String DELIVERED = "SMS_DELIVERED";
Intent delivered = new Intent(DELIVERED);
delivered.putExtra("MsgNum", serialnum);
PendingIntent deliveredPI = PendingIntent.getBroadcast(this,
Integer.parseInt(serialnum), delivered, 0);
这会导致系统搜索与您传入的参数匹配的PendingIntent（在本例中为Intent）。但是，PendingIntent使用的匹配算法仅比较Intent的某些字段，以确定它是否是您要查找的字段。特别是，它不会比较额外内容。这意味着在您创建第一个PendingIntent之后，对PendingIntent.getBroadcast()的调用将始终从池中返回相同的PendingIntent（而不是创建一个新的，这是您想要的）。
为了在每次调用时调用PendingIntent.getBroadcast()创建一个新的PendingIntent，请尝试将传递给调用的参数设为唯一（例如：通过在{中进行操作） {1}}独一无二的）。此外，由于这些Intent中的每一个都只会在获得PendingIntent时设置FLAG_ONE_SHOT时使用：
PendingIntent由于对String DELIVERED = "SMS_DELIVERED" + serialnum; // Unique ACTION every time
Intent delivered = new Intent(DELIVERED);
delivered.putExtra("MsgNum", serialnum);
PendingIntent deliveredPI = PendingIntent.getBroadcast(this,
Integer.parseInt(serialnum), delivered,
PendingIntent.FLAG_ONE_SHOT);
的每次通话都会有不同的行动，这可以解决您的问题。
EDIT2：根据评论中的讨论添加注册广播接收器的替代方法
如果您创建了一个扩展BroadcastReceiver的类，您可以将其添加到清单中，然后根本不需要显式注册广播接收器。像这样：
PendingIntent.getBroadcast()在清单中声明接收者：
public class MessageStatusReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// This is called when the status of your SMS changes (delivery or send status)
// .. put your code here ..
}
}
在发送短信的代码中，执行以下操作：
<receiver android:name=".MessageStatusReceiver" />
