You can create an interface in your Dialog Fragment that your activity must implement. In your Dialog Fragment you can override the "onDetach" method and call the listener activity in that method.

So something along these lines:

import android.app.Activity;
import android.support.v4.app.DialogFragment;

public class MyDialogFragment extends DialogFragment{

    public interface CallBack{
       public void onMyDialogFragmentDetached();
    }

    public CallBack mCallBack;

    @Override
    public void onAttach(Activity activity){
       super.onAttach(activity);
       mCallBack = (CallBack) activity;
    }

    @Override
    public void onDetach(){
       super.onDetach();
       mCallBack.onMyDialogFragmentDetached();
    }

}

Then just have your activity implement MyDialogFragment.CallBack:

  public class MyActivity extends Activity implements MyDialogFragment.CallBack{

    @Override
    public void onMyDialogFragmentDetached(){
       /** Called When MyDialogFragment gets detached. */
    }

  }

I hope that helps. Best of luck.
