收到广播后，我无法从Intent获得数据

Question

我正在写一个程序，用Android系统发送短信。单击“发送”按钮后，我想获得消息的状态，如“已发送”、“已送达”。这部分很好用。问题是，我想得到一个电话号码，信息被发送到该号码，并传送到内部广播。这是必要的，因为SMS可以同时发送给多个用户。我该怎么做？我试着把“不”放在意图上，并把它放进广播接收机，但它不起作用。以下是示例代码：

 public void sendSMS(final String message, final String tele) {
    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";

    SMSStatus sentStatus = new SMSStatus();
    SMSDelivery deliveryStatus = new SMSDelivery();
    //broadcast these during send and delivery
    PendingIntent sentPI = PendingIntent.getBroadcast(SMS.this, 0, new Intent(SENT).putExtra("telephone", tele), 0);
    PendingIntent deliveredPI = PendingIntent.getBroadcast(SMS.this, 0, new Intent(DELIVERED).putExtra("telephone",tele), 0);

    registerReceiver(sentStatus, new IntentFilter(SENT));
    registerReceiver(deliveryStatus, new IntentFilter(DELIVERED));

    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(tele, null, message, sentPI, deliveredPI);
}

和一个广播接收器：

class SMSStatus extends BroadcastReceiver {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            //Toast.makeText(SMS.this, "Sent to " + arg1.getExtras().getString("telephone"), Toast.LENGTH_LONG).show();
            String no = arg1.getExtras().getString("telephone");
            switch (getResultCode()) {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), "Message sent " + no, Toast.LENGTH_SHORT).show();
                    break; 
                ...
           }
}

仅供参考，第一个代码在通过不同电话号码的循环中被调用。

将您的sendSMS代码更改为：

public void sendSMS(final String message, final String tele) {
    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";

    SMSStatus sentStatus = new SMSStatus();
    SMSDelivery deliveryStatus = new SMSDelivery();
    //broadcast these during send and delivery
   PendingIntent sentPI = PendingIntent.getBroadcast(SMS.this, 0, new Intent(SENT).putExtra("telephone", tele), PendingIntent.FLAG_UPDATE_CURRENT);
    PendingIntent deliveredPI = PendingIntent.getBroadcast(SMS.this, 0, new Intent(DELIVERED).putExtra("telephone",tele), PendingIntent.FLAG_UPDATE_CURRENT);

    registerReceiver(sentStatus, new IntentFilter(SENT));
    registerReceiver(deliveryStatus, new IntentFilter(DELIVERED));

    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(tele, null, message, sentPI, deliveredPI);
}
