Question

在我的项目中，我使用SmsManager向我的客户发送消息。如果sms成功发送，我想更改客户端表中的客户端状态。这个名为PassengerInformation.java的类是activity，用于发送短信并更改db中客户端的状态。我发现有一个问题是PassengerInformation活动运行代码更新客户端状态而不知道sms发送成功，它必须等待运行更新代码，直到SmsManager成功发送短信。

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); 
    }   
    }

我发现有一个问题是PassengerInformation活动运行代码更新客户端的状态而不知道sms成功发送，它必须等待运行更新代码，直到Sms成功发送sms .--＆gt;为此，您必须将更新数据库代码保存在SendSMS类的switch / case中。

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

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

发送短信后更新数据库
