如何在android中只调用一次广播接收器？

您好，我遇到了同样的问题，我有一个广播接收器，我从中启动了一个服务，用于从收件箱获取消息。在那之后，我将这些信息发送到特定的号码。对于发送消息，我使用了与上面相同的代码（由John发布）。我的问题是，当我发送消息时，toast消息“SMS SENT”将持续出现。那我怎么能只收到一次呢

我被这件事缠住了，有人能告诉我哪里错了吗

谢谢

我在这里发布了我的代码：-

package z.z.z;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;

public class SMSReceiver extends BroadcastReceiver  
{
    private SmsMessage[] msgs;
    private String strNo,strMsgText;

    @Override
    public void onReceive(Context context, Intent intent) 
    {
        try
        {
            Bundle bundle = intent.getExtras();        
            msgs = null;
            String str = "";         

            if (bundle != null)
            {
                Object[] pdus = (Object[]) bundle.get("pdus");
                msgs = new SmsMessage[pdus.length];
                for (int i=0; i<msgs.length; i++)
                {
                    msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
                    str += "SMS from " + msgs[i].getOriginatingAddress();                     
                    str += ":";
                    str += msgs[i].getMessageBody().toString();
                    str += "\n";
                    strNo = msgs[i].getOriginatingAddress();    
                    strMsgText = msgs[i].getDisplayMessageBody();

                }

                context.startService(new Intent(context,IncomingSMSService.class));

            }
        }
        catch (Exception e) 
        {
            e.printStackTrace();
        }
    }

}

在我看来，你是这样安排的。您的

IncomingSMSService

调用您的

SMSService.sendSMS

函数，该函数注册您的

SMSReceiver

，该函数发送重新启动

IncomingSMSService

的意图，依此类推

尝试删除此链的一个链接，看看它是否解决了重复问题。

实际上，我必须向特定号码发送“SMS send”消息作为通知。这就是我再次从RMACeiver发送SMS的原因。问题是，您正在使用自定义类

SMSService.sendSMS

，该类为发送和传递通知注册接收者。要发送通知文本，请使用vanilla

smsmsmanager.sendTextMessage

，这样您就不会收到无限循环的文本，也不会收到针对这些文本的已发送通知的已发送通知，等等。@Craigy我也有类似的问题，我在这里提出了我的问题：…我无法定位无限循环来自何处，我已经仔细检查了意图的路径，但它似乎是单向的，没有像anddev那样的循环逻辑…但问题仍然存在，一个无限的组中发送的第一条消息列表
