Android-将不断变化的数据从BroadcastReceiver传递到另一个对象？

我有一个Wifi类，它有两个广播接收器，可以监听Wifi连接状态、Wifi Rssi水平等的变化

我希望能够将此数据传递给另一个“引擎”对象，并且仍然保持数据动态变化

目前，我在“Engine”类中创建了一个Wifi对象并运行其方法，然后在Log cat中的Log语句中动态显示数据

我的问题是试图将动态变化的数据传输到引擎，当我试图通过引擎获取数据时，它会获取第一个值并保持不变，而不会进行任何更新

所以我想知道我的选择是什么

以下是我当前的代码设置（如果有帮助）：

Wifi类

public Wifi(Context context){

    mainWifi = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);

}

public int getCurrentWifiState() {
    return currentWifiState;
}

public void setCurrentWifiState(int currentWifiState) {
    this.currentWifiState = currentWifiState;
}

public String getConnectedSSID() {
    return connectedSSID;
}

public void setConnectedSSID(String connectedSSID) {
    this.connectedSSID = connectedSSID;
}

public int getConnectedLevel() {
    return connectedLevel;
}

public void setConnectedLevel(int connectedLevel) {
    this.connectedLevel = connectedLevel;
}

//method to do a scan and receive info about all access points available
public List<ScanResult> scan(final Context context){

               receiverWifi = new WifiReceiver();
               mainWifi = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);

               context.registerReceiver(receiverWifi, new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));
               mainWifi.startScan();
               Log.d("WIFI DEBUG","\nStarting Scan...\n"); 
               wifiList = mainWifi.getScanResults();

    return wifiList; 
}

 class WifiReceiver extends BroadcastReceiver {
     public void onReceive(Context c, Intent intent) {
          sb = new StringBuilder();
          wifiList = mainWifi.getScanResults();
          ListIterator<ScanResult> results = wifiList.listIterator();

          while (results.hasNext()) {
              ScanResult info = results.next();
              String wifiInfo = "Name: " + info.SSID + "; capabilities = " + info.capabilities + "; sig str = " + info.level + "dBm";
              Log.v("WiFi", wifiInfo);
              Log.d("Signal Level", "Signal Level : " + mainWifi.calculateSignalLevel(info.level, 5));

          }
     }
 }

 //method to listen for changes in the level of the wifi connection
 public void initializeWiFiListener(Context context){
        Log.d("WIFI", "executing initializeWiFiListener");

        String connectivity_context = Context.WIFI_SERVICE;
        final WifiManager wifi = (WifiManager)context.getSystemService(connectivity_context);

        if(!wifi.isWifiEnabled()){
                if(wifi.getWifiState() != WifiManager.WIFI_STATE_ENABLING){
                        //wifi.setWifiEnabled(true);
                }
        }
        rssiListener = new BroadcastReceiver(){

                @Override
                public void onReceive(Context context, Intent intent) {
                        String action = intent.getAction();

                        if(WifiManager.RSSI_CHANGED_ACTION.equals(action)){
                            WifiInfo data = mainWifi.getConnectionInfo();
                            Log.d("WIFI", "RSSI has changed");
                            if(mainWifi.getConnectionInfo()!=null){
                            setConnectedSSID(data.getSSID());
                            setConnectedLevel(data.getRssi());
                            Log.d("WIFI", "new RSSI = " + data.getSSID()+ " " + data.getRssi() + "dBm");
                            }
                        }      
                }
        };
        //leak here - need to de reg receiver
        context.registerReceiver(rssiListener, new IntentFilter(WifiManager.RSSI_CHANGED_ACTION));
}

 //method to listen for changes in the connection to a wifi access point
 public void changeWiFiListener(Context context){
        Log.d("WIFI", "executing initializeWiFiListener");

        String connectivity_context = Context.WIFI_SERVICE;

                }
        }

        };
        //Leak here - not unregistering receiver
        context.registerReceiver(wifiChangeListener, new IntentFilter(WifiManager.WIFI_STATE_CHANGED_ACTION));

因此，我只是想知道什么是最好的解决方案，以确保当引擎从广播接收器接收到更改时，来自Wifi类的数据在引擎中不断更新？

取决于您的类，即应该被通知最新状态的类。 如果该类不是在活动中创建的，并且是静态的（单音或基于应用程序），那么您可能应该让接收器更新单音类

如果是基于活动的，则需要粘贴广播，一旦接收到广播，请删除粘贴广播

public Engine(Context aContext){

        context = aContext;

        cm = new CallManager(aContext);

        wifiManager = new Wifi(context);
        wifiManager.initializeWiFiListener(context);
        wifiManager.changeWiFiListener(context);    

        clc = new CallLogController();
    }

    public void controlCalls(){

        int currentWifiState = wifiManager.getCurrentWifiState();
        cm.monitorOutgoingCalls(context, currentWifiState, clc);

    }

    public void unRegAllRecievers(){

        wifiManager.unregRegisters(context);
        cm.unRegReciever(context);

    }

    public void doWifiScan(){

        scanTask = new TimerTask() {
            public void run() {
                    handler.post(new Runnable() {
                            public void run() {
                                wifiManager.scan(context); 
                                Log.d("TIMER", "Timer set off");
                            }
                   });
            }};

        t.schedule(scanTask, 300, 30000);
    }

    public void stopScan(){ 

            scanTask.cancel();
            t.cancel();
            //boolean tf = scanTask.cancel();
            //Log.d("TIMER", "Timer True or False? : " + tf);
    }
}
