【问题描述】：

我是 android 编程的初学者。我正在尝试在 android 设备中实现传入 SMS 的通知。但是，我可以为相同的内容创建一个 toast，但无法实现状态栏通知。 谁能帮帮我？

现在我已经编写了以下代码：

 @Override
        public void onReceive(Context arg0, Intent arg1) 
        

    //      Log.i(TAG,"OnReceive ++      ");
            Bundle bndl = arg1.getExtras();
            SmsMessage[] msg = null;

            if (null != bndl)
            
                //---retrieve the SMS message received---
                Object[] pdus = (Object[]) bndl.get("pdus");
                msg = new SmsMessage[pdus.length];         
                for (int i=0; i<msg.length; i++)
                
                    msg[i] = SmsMessage.createFromPdu((byte[])pdus[i]);             
                    str += "SMS From " + msg[i].getOriginatingAddress();                   
                    str += " :\r\n";
                    str += msg[i].getMessageBody().toString();
                    str += "\n";
                    context = arg0;
                

                //---display incoming SMS as a Android Toast---
                Toast.makeText(arg0, str, Toast.LENGTH_SHORT).show();
                @SuppressWarnings("unused")
                class MynotificationMain extends Activity 
                
                    int mNotificationId = 001;

                    @Override
                    protected void onCreate(Bundle savedInstanceState) 
                    
                        super.onCreate(savedInstanceState);
                        //setContentView(R.layout.activity_mynotification_main);
                        NotificationCompat.Builder  mBuilder = new   NotificationCompat.Builder(context);
                          mBuilder.setContentTitle("New Message");
                          mBuilder.setContentText(str);
                          mBuilder.setTicker("New Message Alert!");
                          mBuilder.setSmallIcon(R.drawable.notification);

                        Intent resultIntent  = new Intent(this, MainActivity.class );
                        PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);

                        mBuilder.setContentIntent(resultPendingIntent);

                        NotificationManager mNotifyMgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
                        mNotifyMgr.notify(mNotificationId, mBuilder.build());

                        MapsFragment obj = new MapsFragment();
                        obj.onLocationChanged(null);
                    
                
            

        
    

【问题讨论】：

你为什么要使用这样的活动？对我来说，弄清楚你哪里出错了，这甚至没有足够的意义。

这只是一次疯狂的尝试，因为我只是一个初学者。你能解释一下我应该如何获得状态栏通知吗？

【参考方案1】：

为什么要在方法中进行活动？应该是

@Override
public void onReceive(Context arg0, Intent arg1) 

 Bundle bndl = arg1.getExtras();
 SmsMessage[] msg = null;
 if (null != bndl)
 
   //---retrieve the SMS message received---
   Object[] pdus = (Object[]) bndl.get("pdus");
   msg = new SmsMessage[pdus.length];         
   for (int i=0; i<msg.length; i++)
   
     msg[i] = SmsMessage.createFromPdu((byte[])pdus[i]);             
     str += "SMS From " + msg[i].getOriginatingAddress();                   
     str += " :\r\n";
     str += msg[i].getMessageBody().toString();
     str += "\n";
   

   //---display incoming SMS as a Android Toast---
   Toast.makeText(arg0, str, Toast.LENGTH_SHORT).show();
   //---Make a notification          
   NotificationCompat.Builder  mBuilder = new   NotificationCompat.Builder(context);
   mBuilder.setContentTitle("New Message");
   mBuilder.setContentText(str);
   mBuilder.setTicker("New Message Alert!");
   mBuilder.setSmallIcon(R.drawable.notification);

   Intent resultIntent  = new Intent(this, MainActivity.class );
   PendingIntent resultPendingIntent = PendingIntent.getActivity(arg0, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);

   mBuilder.setContentIntent(resultPendingIntent);

   NotificationManager mNotifyMgr = (NotificationManager) arg0.getSystemService(arg0.NOTIFICATION_SERVICE);
   mNotifyMgr.notify(mNotificationId, mBuilder.build());

 

【讨论】：

问题是我的父类扩展了 BroadcastReceiver。我需要活动类来实现 getSystemService。

你的上下文为 arg0。然后只需调用 arg0.getSystemService

在扩展 BroadcastReceiver 的父类中实现通知代码时出现错误。有什么解决办法吗？

好的，首先它在 getActivity 中给了我错误：PendingIntent 类型中的方法 getActivity(Context, int, Intent, int) 不适用于参数 (MyBroadcastReceiver, int, Intent, int) ！

它在 NOTIFICATION_SERVICE 中给出错误：NOTIFICATION_SERVICE 无法解析为变量
