Delivery Intent的pdu是否包含发送SMS的人的电话号码？

Question

我试图找出人的电话号码给谁的短信是从Intent的PDU交付广播接收机的onReceive()发出这样

@Override 
public void onReceive(Context context, Intent intent) { 
    ThizLog.d(TAG, "Inside onReceive"); 
    Bundle bundle = intent.getExtras(); 
    Object[] messages = (Object[]) bundle.get("pdus"); 
    SmsMessage[] sms = new SmsMessage[messages.length]; 

    for (int n = 0; n < messages.length; n++) { 
     sms[n] = SmsMessage.createFromPdu((byte[]) messages[n]); 
    } 
    for (SmsMessage msg : sms) { 
     // Verify if the message came from our known sender 
     ThizLog.d(TAG,"!!! " + msg.getOriginatingAddress()); 

    } 
    switch (getResultCode()) { 
     case Activity.RESULT_OK: 
      // SMS delivered 
      break; 
     case Activity.RESULT_CANCELED: 
      /* 
      * SMS not delivered, show SMS_NOT_DELIVERED_MESSAGE 
      */ 
      Toast toast = Toast.makeText(context, SMS_NOT_DELIVERED_MESSAGE, Toast.LENGTH_LONG); 
      // shows toast on left top corner increase the zero value to 
      // slide it right and down 
      //toast.setGravity(Gravity.TOP | Gravity.LEFT, 0, 0); 
      toast.show(); 
      break; 
    } 
} 

，但是这导致以下错误

这是可能的，Android的本机短信应用程序做到这一点。

我认为你没有从收到的意图中正确获得pdu。这将是一个单独的pdu，而不是一个数组。

试试这个：

public void onReceive(Context context, Intent intent) { 
    String pdu=intent.getStringExtra("pdu"); 

    ... 
}
