如何在Android中识别哪些短信有送达报告

Question

我的应用程序通过根据记录的大小合并记录来从 sqlite 数据库和 SMS 中检索记录到其他应用程序，我无法确定哪些消息已获得传递报告而哪些没有。我在 reciveMethods 上使用 BroadcastReceiver 但不幸的是，我无法理解如何识别。如果你们中的任何人建议我如何处理这个问题，我会很高兴。或者其他更好的方法

您需要将您需要的数据放入PendingIntent，当交付完成（或失败）时将广播该数据。执行此操作时，您需要确保为每条消息创建一个唯一的PendingIntent（您可以通过在Intent 上设置一个唯一的操作来做到这一点）。这是一个例子。

而不是这个：

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

这样做：

    long messageID = ... // This is the message ID, ie: the row ID in the SQLite database that uniquely identifies this message
    Intent deliveredIntent = new Intent(DELIVERED + messageID); // Use unique action string
    deliveredIntent.putExtra("messageID", messageID); // Add message ID as extra
    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
           deliveredIntent, PendingIntent.FLAG_ONE_SHOT);

注册接收方时，一定要使用正确的IntentFilter：

    registerReceiver(new BroadcastReceiver(){
        ...
    }, new IntentFilter(DELIVERED + messageID));

现在，当发送Intent 广播时，您可以从onReceive() 中获取数据，如下所示：

    public void onReceive(Context arg0, Intent arg1) {
        long messageID = arg1.getLongExtra("messageID", -1L);
        if (messageID != -1L) {
            // This is the message ID (row ID) of the message that was delivered
            ... do your processing here
        }
