Question

我遇到了像use registerReceiver for non activity and non service class这样的问题。我尝试使用Google Message Cloud，我需要从一个活动注册BroadCastReceiver并从另一个活动中注销它。为此，我将BroadcastReceiver放在除活动之外的另一个包中在我的活动中：

    public void onPushStateButtonClicked(View view) {
            // controllo se il bottone è su on
            boolean on = ((ToggleButton) view).isChecked();
            PushClientService p = new PushClientService();
            if (on) {
                // se il bottone  in impostazioni è settato ad on registro il dispositivo
                p.customReceiver(this);
                p.pushService(this);
            }else if(!on) {
                // se il bottone  in impostazioni è settato ad off cancello il dispositivo

                try{    
                    GCMRegistrar.unregister(this);
                    p.customUnregisterReceiver(this);

                }catch(IllegalArgumentException iAE){
                    Log.e("Errore:","device non registrato "+iAE);
                }
            }
}

在另一个班级我是这样的：

private final BroadcastReceiver mHandleMessageReceiver =
            new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                String newMessage = intent.getExtras().getString(EXTRA_MESSAGE);
                Log.d("Message",newMessage);
            }
        };
        public void customReceiver(Context context){
            context.registerReceiver(mHandleMessageReceiver,
                    new IntentFilter(DISPLAY_MESSAGE_ACTION));
        }
        public void customUnregisterReceiver(Context context){
            context.unregisterReceiver(mHandleMessageReceiver);
        }

这就是清单：

    </application>

</manifest>

当我取消注册接收者时，mHandleMessageReceiver的值与注册不同，我该怎么办？使mHandleMessageReceiver静态？

请给我一个想法tnks
