方法registerReceiver(BroadcastReceiver,IntentFilter)未定义类型SMSReceiver

Question

我正在尝试开发一个简单的位置跟踪应用程序,我已经使用了broadcastReceivers.我使用简单的短信发送方法来获取设备的位置.我想在发送和接收短信后获得反馈.但是我在注册接收器时遇到错误.我得到的错误是方法registerReceiver(BroadcastReceiver,IntentFilter)未定义类型SMSReceiver.MyLocationListener.请帮我解决一下这个.

这是我的代码:

private class MyLocationListener implements LocationListener
    {

        @Override
        public void onLocationChanged(Location loc) 
        {

            if(loc!=null)
            {
                //send a sms containing the current location
                SmsManager sms = SmsManager.getDefault();
                sms.sendTextMessage(senderTel, null, "http://maps.google.com/maps?q" + loc.getLatitude() + "," + loc.getLongitude(), null, null);
                BroadcastReceiver smsSentReceiver = new BroadcastReceiver()
                {

                    @Override
                    public void onReceive(Context arg0, Intent arg1) 
                    {
                        switch(getResultCode())
                        {
                            case Activity.RESULT_OK:
                                Toast.makeText(arg0, "SMS sent", Toast.LENGTH_LONG).show();
                                break;
                            case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                                Toast.makeText(arg0, "generic failure", Toast.LENGTH_LONG).show();
                                break;
                            case SmsManager.RESULT_ERROR_NO_SERVICE:
                                Toast.makeText(arg0, "No service", Toast.LENGTH_LONG).show();
                                break;
                            case SmsManager.RESULT_ERROR_NULL_PDU:
                                Toast.makeText(arg0, "Null PDU", Toast.LENGTH_LONG);
                                break;
                            case SmsManager.RESULT_ERROR_RADIO_OFF:
                                Toast.makeText(arg0, "Radio Off", Toast.LENGTH_LONG).show();
                                break;
                        }

                    }

                };
                // stop listening for location change
                lm.removeUpdates(locationListener);
                smsDeliveredReceiver= new BroadcastReceiver()
                {

                    @Override
                    public void onReceive(Context arg0, Intent arg1) 
                    {
                        switch(getResultCode())
                        {
                        case Activity.RESULT_OK:
                            Toast.makeText(arg0, "SMS delivered", Toast.LENGTH_LONG).show();
                            break;
                        case Activity.RESULT_CANCELED:
                            Toast.makeText(arg0, "SMS not delivered", Toast.LENGTH_LONG).show();
                            break;
                        }

                    }

                };
                registerReceiver(smsDeliveredReceiver, new IntentFilter(DELIVERED));

Answer 1

你需要一个上下文来调用registerReceiver(); ,例如活动或服务.

这将是这样做的:

theContext.registerReceiver(smsDeliveredReceiver, new IntentFilter(DELIVERED));
