在一个服务中，当广播接收者循环发送短信并监听发送报告时，如何区分发送的每条短信的发送报告？ 这类似于: How to get Delivery Report of each SMS sent in loop android?

除了我认为他在 Activity 中使用它而我在 getIntent() 无效的服务中使用它。

最佳答案

您可以像这样将消息编号额外添加到 Intent 中:

delivered.putExtra("MsgNum", serialnum);

然后你尝试像这样提取它:

USS.execute(intent.getStringExtra("Msgnum"));

在putExtra()中你有大写的“N”，在getStringExtra()中你使用小写的“n”.

这就是为什么你应该总是对这样的东西使用常量。它可以防止您花费数小时试图查找由打印错误引起的错误。

public static final String EXTRA_MSGNUM = "MsgNum";

delivered.putExtra(EXTRA_MSGNUM, serialnum);

USS.execute(intent.getStringExtra(EXTRA_MSGNUM));

String DELIVERED = "SMS_DELIVERED";
Intent delivered = new Intent(DELIVERED);
delivered.putExtra("MsgNum", serialnum);
PendingIntent deliveredPI = PendingIntent.getBroadcast(this,
                    Integer.parseInt(serialnum), delivered, 0);

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);

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 ..
   }
}

<receiver android:name=".MessageStatusReceiver" />

String DELIVERED = "SMS_DELIVERED" + serialnum; // Unique ACTION every time
Intent delivered = new Intent(context, MessageStatusReceiver.class);
delivered.setAction(DELIVERED ); // Set action to ensure unique PendingIntent
delivered.putExtra("MsgNum", serialnum);
PendingIntent deliveredPI = PendingIntent.getBroadcast(this,
                    Integer.parseInt(serialnum), delivered,
                    PendingIntent.FLAG_ONE_SHOT);
