如何檢索來電的號碼並在拒絕來電時發送短信？

Question

當有人打電話時，如果我拒絕或放棄呼叫，我的應用程序會向呼叫者發送自動回覆。但是當我拒絕呼叫時，AVD顯示一條消息 - 「不幸Autoreply2Caller停止」。請幫助。這裏是我的源代碼： 包bd.com.example.autoreply2caller;

import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.os.Bundle; 
import android.telephony.SmsMessage; 
import android.telephony.TelephonyManager; 
import android.telephony.gsm.SmsManager; 
import android.widget.Toast; 

public class ReplyToCaller extends BroadcastReceiver { 

    @Override 
    public void onReceive(Context context, Intent intent) { 

     // Toast.makeText(context, "SMS Received: " + intent.getAction(), 
     // Toast.LENGTH_LONG).show(); 

     if (intent.getAction() 
       .equals("android.provider.Telephony.SMS_RECEIVED")) { 
      // extract the SMS 
      Bundle bundle = intent.getExtras(); 
      SmsMessage[] chunks = null; 
      String number = ""; 
      String text = ""; 

      if (bundle != null) { 
       Object[] pdus = (Object[]) bundle.get("pdus"); 
       chunks = new SmsMessage[pdus.length]; 
       for (int i = 0; i < pdus.length; i++) { 
        chunks[i] = SmsMessage.createFromPdu((byte[]) pdus[i]); 
        text += chunks[i].getMessageBody(); 
        number = chunks[i].getOriginatingAddress(); 
       } 
      } 
      Toast.makeText(context, 
        "SMS Received: from: " + number + " Message Body: " + text, 
        Toast.LENGTH_LONG).show(); 
      // send an automatic reply 
      SmsManager smsManager = SmsManager.getDefault(); 
      smsManager.sendTextMessage(number, null, 
        "I am busy right now. I'll call you later.", null, null); 

     } 

     // reply to the caller 
     String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE); 

     if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) { 
      // Phone is ringing 

     } else if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) { 
      // Call received 

     } else if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) { 
      // Call Dropped or rejected 
      String number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER); 


      // send an automatic reply 
      SmsManager smsManager = SmsManager.getDefault(); 
      smsManager.sendTextMessage(number, null, 
        "I am busy right now. I'll call you later.", null, null); 

     } 

    } 
}

收聽電話狀態使用PhoneStateListener見：this answer

嘗試smsMessages[n].getDisplayOriginatingAddress()

我總是從SMS拉動地址，像這樣：

Object messages[] = (Object[]) bundle.get("pdus"); 
smsMessages = new SmsMessage[messages.length]; 

for (int n = 0; n < messages.length; n++) 
{ 
    smsMessages[n] = SmsMessage.createFromPdu((byte[]) messages[n]); 
    JLog.v("Reciever: SMS :-\r\n ========== \r\n " 
      + smsMessages[n].getDisplayOriginatingAddress() + "\r\n " 
      + smsMessages[n].getServiceCenterAddress() + "\r\n " 
      + smsMessages[n].getDisplayMessageBody() 
      + "\r\n========"); 
} 

此外，您可能必須做的重新發送短信是確保號碼格式化！記錄這些東西真的有幫助！

傳出電話號碼需要看起來像4412345123456或任何其他有效的號碼。

PhoneNumberUtils爲您提供了格式化方法。
