udpate數據庫後發送短信

Question

在我的項目中，我用SmsManager發送消息給我的客戶。如果短信發送成功，我想更改客戶端表中的客戶端狀態。這個名爲PassengerInformation.java的類是activity，用於發送短信並更改db中客戶端的狀態。有一個問題，我發現PassengerInformation活動的客戶端更新狀態運行代碼不知道sms是否成功發送，它必須等待運行代碼的更新，直到短信成功發送SmsManager。任何建議表示讚賞。

感謝，

PassengerInformation.java

public class PassengerInformation extends BaseFragment{ 
public static Boolean messageSending= false; 
@Override 
public void onViewCreated(View view, Bundle savedInstanceState) 
{ 
    SendSMS sms=new SendSMS(v.getContext()); 
    sms.sendSMS("83939420",builder.toString()); 
    if(messageSending){ 
     //update database 
    } 
} 

SendSMS.java

public class SendSMS { 
    Context mContext; 
    String SENT = "SMS_SENT"; 
    String DELIVERED = "SMS_DELIVERED"; 

    ArrayList<PendingIntent> sentIntents; 
    ArrayList<PendingIntent> deliveryIntents; 

public SendSMS(Context c){ 
    mContext=c; 
} 
public void sendSMS(String phoneNumber, String message) 
    {    

     SmsManager sm = SmsManager.getDefault(); 
     ArrayList<String> parts =sm.divideMessage(message); 
     int numParts = parts.size(); 

     sentIntents = new ArrayList<PendingIntent>(); 
     deliveryIntents = new ArrayList<PendingIntent>(); 

     for (int i = 0; i < numParts; i++) { 
      sentIntents.add(PendingIntent.getBroadcast(mContext, 0, new Intent(SENT), 0)); 
      deliveryIntents.add(PendingIntent.getBroadcast(mContext, 0, new Intent(DELIVERED), 0)); 
      } 
     //---when the SMS has been sent--- 
     mContext.registerReceiver(new BroadcastReceiver(){ 
      @Override 
      public void onReceive(Context arg0, Intent arg1) { 
       switch (getResultCode()) 
       { 
        case Activity.RESULT_OK: 
         Toast.makeText(mContext, "SMS sent", Toast.LENGTH_SHORT).show(); 
         PassengerInformation.messageSending=true; 
         break; 
        case SmsManager.RESULT_ERROR_GENERIC_FAILURE: 
         Toast.makeText(mContext, "Generic failure",Toast.LENGTH_SHORT).show(); 
         PassengerInformation.messageSending=false; 
         break; 
        case SmsManager.RESULT_ERROR_NO_SERVICE: 
         Toast.makeText(mContext, "No service",Toast.LENGTH_SHORT).show(); 
         PassengerInformation.messageSending=false; 
         break; 
        case SmsManager.RESULT_ERROR_NULL_PDU: 
         Toast.makeText(mContext, "Null PDU",Toast.LENGTH_SHORT).show(); 
         PassengerInformation.messageSending=false; 
         break; 
        case SmsManager.RESULT_ERROR_RADIO_OFF: 
         Toast.makeText(mContext, "Radio off",Toast.LENGTH_SHORT).show(); 
         PassengerInformation.messageSending=false; 
         break; 
       } 
      } 
     }, new IntentFilter(SENT)); 

     //---when the SMS has been delivered--- 
     mContext.registerReceiver(new BroadcastReceiver(){ 
      @Override 
      public void onReceive(Context arg0, Intent arg1) { 
       switch (getResultCode()) 
       { 
        case Activity.RESULT_OK: 
         Toast.makeText(mContext, "SMS delivered", 
           Toast.LENGTH_SHORT).show(); 
         PassengerInformation.messageSending=true; 
         break; 
        case Activity.RESULT_CANCELED: 
         Toast.makeText(mContext, "SMS not delivered", 
           Toast.LENGTH_SHORT).show(); 
         PassengerInformation.messageSending=false; 
         break;       
       } 
      } 
     }, new IntentFilter(DELIVERED));   

     SmsManager sms = SmsManager.getDefault(); 
     sms.sendMultipartTextMessage(phoneNumber, null, parts, sentIntents, deliveryIntents); 
    } 
    }

還有就是我發現了一個問題，那就是更新的狀態PassengerInformation活動運行代碼不知道短信的客戶端發送成功，它必須等待runni ng代碼的更新，直到SmsManager成功發送短信。 - >因爲你必須保持你的更新數據庫代碼在開關/ SendSMS類的情況下。

case Activity.RESULT_OK: 
    Toast.makeText(mContext, "SMS sent", Toast.LENGTH_SHORT).show(); 
    PassengerInformation.messageSending=true; 

    if(messageSending){ 
     //update database 
     } 
break;
