從父活動繼承BroadcastReceiver活動

我有三個活動：BaseActivity，ActivityA，ActivityB其中ActivityA和B擴展了BaseActivity。在ActivityA和B中，我都有一個處理一些意圖的BroadcastReceiver。在ActivityA和B中有一些目前由相同代碼處理的相同意圖。由於這違反了DRY原則，我想在父類（BaseActivity）中處理ActivityA和B中的常見意圖。是否有可能這樣做？從父活動繼承BroadcastReceiver活動

這裏是代碼。意圖LOGIN_SUCCESS在ActivityA和B中都是相同的。而ACCOUNT_UPDATE和JOURNAL_UPDATE意圖是特定於這些類的。

public abstract class BaseActivity extends RoboActivity implements Handler.Callback { 

} 


public class ActivityA extends BaseActivity { 

    private final BroadcastReceiver intentReceiver = new BroadcastReceiver() { 
     @Override 
     public void onReceive(Context context, Intent intent) { 
     if (intent.getAction().equals(Constants.INTENTS.ACCOUNT_UPDATE)) { 
      updateGUI(); 
     } 

     if (intent.getAction().equals(Constants.INTENTS.LOGIN_SUCCESS)) { 
      updateGUI(); 
     } 
    }; 

    @Override 
    protected void onResume() { 
     super.onResume(); 
     // Register which actions to listen to 
     IntentFilter intentFilter = new IntentFilter(Constants.INTENTS.ACCOUNT_UPDATE); 
     intentFilter.addAction(Constants.INTENTS.LOGIN_SUCCESS); 
     LocalBroadcastManager.getInstance(getApplicationContext()).registerReceiver(intentReceiver, intentFilter); 
    } 
} 

public class ActivityB extends BaseActivity { 

    private final BroadcastReceiver intentReceiver = new BroadcastReceiver() { 
     @Override 
     public void onReceive(Context context, Intent intent) { 
      if(intent.getAction().equals(Constants.INTENTS.JOURNAL_UPDATE)){ 
      updateGUI(); 
     } 

     if (intent.getAction().equals(Constants.INTENTS.LOGIN_SUCCESS)) { 
      updateGUI(); 
     } 
     } 
    }; 

    @Override 
    protected void onResume() { 
     super.onResume(); 
     // Register which actions to listen to 
     IntentFilter intentFilter = new IntentFilter(Constants.INTENTS.JOURNAL_UPDATE); 
     intentFilter.addAction(Constants.INTENTS.LOGIN_SUCCESS); 
     LocalBroadcastManager.getInstance(getApplicationContext()).registerReceiver(intentReceiver, intentFilter); 
    } 
}
