Android 在onReceive（）侦听之前注销广播调用

我正在开发一个android短信应用程序。下面的代码是我用来发送短信的

 public void sendsms(){
 sendBroadcastReceiver=new BroadcastReceiver() {
       @Override
        public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub
            switch (getResultCode()) {

                case Activity.RESULT_OK:
                    System.out.println("hereeeeeeeeeeeeeeeeeeeeeeeeeeeeee8888888888888888");
                    System.out.println("1111111111111111111111111111111111");
                    Toast.makeText(getBaseContext(), "SMS sent",
                        Toast.LENGTH_SHORT).show();
                    ContentValues values = new ContentValues();
                    values.put("address", phoneNumber);
                    values.put("body", message);
                    getContentResolver().insert(Uri.parse("content://sms/sent"), values);
                    afterSend();
                    break;

                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    Toast.makeText(getBaseContext(), "Generic failure",
                        Toast.LENGTH_SHORT).show();
                    System.out.println("222222222222222222222222222");
                    break;
                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    Toast.makeText(getBaseContext(), "No service",
                        Toast.LENGTH_SHORT).show();
                    System.out.println("333333333333333333333333333333333");
                    ContentValues values1 = new ContentValues();

                    values1.put("address", phoneNumber);
                    values1.put("body", message);
                    getContentResolver().insert(Uri.parse("content://sms/queued"), values1);
                    afterSend();
                    break;
                case SmsManager.RESULT_ERROR_NULL_PDU:
                    System.out.println("44444444444444444444444444");
                    Toast.makeText(getBaseContext(), "Null PDU",
                        Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_RADIO_OFF:
                    System.out.println("4444444444444444444444444444444444");
                    Toast.makeText(getBaseContext(), "Radio off",
                        Toast.LENGTH_SHORT).show();
                    break;



                default:
                    break;
            }               
        }
    };     

    registerReceiver(sendBroadcastReceiver , new IntentFilter(SENT));


    //--- when the SMS hasbeen delivered---

    deliveryBroadcastReciever=new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub

            switch (getResultCode())
            {
                case Activity.RESULT_OK:
                    System.out.println("okkkkkkkkkkkkkkkkkkkkkkkkkkk");
                    Toast.makeText(getBaseContext(), "SMS delivered",
                            Toast.LENGTH_SHORT).show();
                    break;
                case Activity.RESULT_CANCELED:
                    System.out.println("cancellllllllllllllllllll");
                    Toast.makeText(getBaseContext(), "SMS not delivered",
                            Toast.LENGTH_SHORT).show();
                    break;
            }               
        }
    };

    registerReceiver(deliveryBroadcastReciever, new IntentFilter(DELIVERED));


    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);


    unregisterReceiver(sendBroadcastReceiver);
    unregisterReceiver(deliveryBroadcastReciever);
}

现在我的问题是，如果我发送短信，在

sentsms

到达

onreceive（）

之前，广播未注册。因此，在大多数情况下，无法访问onreceive（）开关块（）。如果我没有写注销呼叫，那么在发送第二条短信时，

onreceive（）

将同时监听第一条和第二条短信

---

因此，请在完成

onreceive（）

后通过取消注册调用帮助解决此问题。我已部分解决了此问题。 我从sms方法的末尾删除了unregister（broadcast），并将其放在onreceive（）方法中。因此，unregister（）将仅在到达onreceive（）之后发生。我的工作代码粘贴在下面

 public void sendsms(){
 sendBroadcastReceiver=new BroadcastReceiver() {
       @Override
        public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub
            switch (getResultCode()) {

                case Activity.RESULT_OK:
                    System.out.println("hereeeeeeeeeeeeeeeeeeeeeeeeeeeeee8888888888888888");
                    System.out.println("1111111111111111111111111111111111");
                    Toast.makeText(getBaseContext(), "SMS sent",
                        Toast.LENGTH_SHORT).show();
                    ContentValues values = new ContentValues();
                    values.put("address", phoneNumber);
                    values.put("body", message);
                    getContentResolver().insert(Uri.parse("content://sms/sent"), values);
                    afterSend();
                    break;

                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    Toast.makeText(getBaseContext(), "Generic failure",
                        Toast.LENGTH_SHORT).show();
                    System.out.println("222222222222222222222222222");
                    break;
                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    Toast.makeText(getBaseContext(), "No service",
                        Toast.LENGTH_SHORT).show();
                    System.out.println("333333333333333333333333333333333");
                    ContentValues values1 = new ContentValues();

                    values1.put("address", phoneNumber);
                    values1.put("body", message);
                    getContentResolver().insert(Uri.parse("content://sms/queued"), values1);
                    afterSend();
                    break;
                case SmsManager.RESULT_ERROR_NULL_PDU:
                    System.out.println("44444444444444444444444444");
                    Toast.makeText(getBaseContext(), "Null PDU",
                        Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_RADIO_OFF:
                    System.out.println("4444444444444444444444444444444444");
                    Toast.makeText(getBaseContext(), "Radio off",
                        Toast.LENGTH_SHORT).show();
                    break;



                default:
                    break;
            }
                            context.unregister(this);               
        }
    };     

    registerReceiver(sendBroadcastReceiver , new IntentFilter(SENT));


    //--- when the SMS hasbeen delivered---

    deliveryBroadcastReciever=new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub

            switch (getResultCode())
            {
                case Activity.RESULT_OK:
                    System.out.println("okkkkkkkkkkkkkkkkkkkkkkkkkkk");
                    Toast.makeText(getBaseContext(), "SMS delivered",
                            Toast.LENGTH_SHORT).show();
                    break;
                case Activity.RESULT_CANCELED:
                    System.out.println("cancellllllllllllllllllll");
                    Toast.makeText(getBaseContext(), "SMS not delivered",
                            Toast.LENGTH_SHORT).show();
                    break;
            }   
            context.unregister(this)            
        }
    };

    registerReceiver(deliveryBroadcastReciever, new IntentFilter(DELIVERED));


    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);



}

现在我的代码在sendBroadcastReceiver上运行良好

但是在DeliveryBroadcastReceiver的情况下，接收者（）从不监听任何传递。因此DeliveryBroadcastReceiver正在注册每个发送短信

所以我试着用onstop（）

---

但是onStop（）只注销最后一个registerd deliveryBroadcastReceiver对象。如果我发送两次sms，将有两个deliveryBroadcastReceiver对象，onStop（）只注销最后一个对象。请帮助我的朋友。

使用onResume和onPause注册和注销。@PoweRoy..你能解释一下吗..我如何注册每条短信？

@Override
protected void onStop() {
    // TODO Auto-generated method stub
    super.onStop();
             unregister(deliveryBroadcastReceiver);
             }
