    Bundle bundle = intent.getExtras(); 
    Object[] pdusObj = (Object[]) bundle.get("pdus"); 
    SmsMessage[] messages = new SmsMessage[pdusObj.length]; 
    for (int i = 0; i<pdusObj.length; i++) 
    { 
            messages[i] = SmsMessage.createFromPdu ((byte[]) 
            pdusObj[i]); 
            sender = messages[i].getOriginatingAddress();
            sms = messages[i].getMessageBody();//save sms to string
    } 

    for (SmsMessage msg …

我想计算文件中的行数,将其分成标记.我似乎无法让我的代码工作,有人可以提供建议.提前致谢
