DialogFragment中的选项菜单

我有两个片段，一个是列表片段，另一个是我使用它一次作为对话框，并且作为片段菜单选项存在我的问题，在列表片段中有一个显示总是动作的项目菜单，而在对话框片段中我不想要这个项目是可见的，我也不希望选项菜单也可见，我已经尝试过

setHasOptionMenu(false)

但它不起作用，并试图setHasOptionMenu(true)清除菜单中的所有项目，但均不起作用。

另外，我的父母活动没有选项菜单的任何代码。这是我的代码：

@SuppressLint("InflateParams")
public class FormGeneratorActivity extends DialogFragment {
Control mControl;
boolean doChangeTitle;
private boolean isDialog;
public static int CreatedNum = 0;


public static FormGeneratorActivity getInstance(Control mControl, boolean doChangeTitle) {
    FormGeneratorActivity frag = new FormGeneratorActivity();
    Bundle b = new Bundle();
    b.putParcelable("control", mControl);
    b.putBoolean("changeTitle", doChangeTitle);
    frag.setArguments(b);
    return frag;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (getArguments() != null) {
        doChangeTitle = getArguments().getBoolean("changeTitle");
    }
    setHasOptionsMenu(false);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    return super.onOptionsItemSelected(item);
}

@Override
public void onPrepareOptionsMenu(Menu menu) {
    menu.clear();
    activity.invalidateOptionsMenu();
    super.onPrepareOptionsMenu(menu);

}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
}



public void setDoChangeTitle(boolean doChangeTitle) {
    this.doChangeTitle = doChangeTitle;
}

View view;
boolean isInflated = false;
ParentActivity activity;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (view == null) {
        mControl = getArguments().getParcelable("control");
        view = inflater.inflate(R.layout.form_generator_fragment, container, false);
        container = (LinearLayout) view.findViewById(R.id.cont);
        isInflated = true;
    } else {
        if (view.getParent() != null)
            ((ViewGroup) view.getParent()).removeAllViews();
        isInflated = false;
    }

    return view;
}

String headerPageTitle = null;

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    activity = (ParentActivity) getActivity();
    activity.getSupportActionBar().invalidateOptionsMenu();

        CreatedNum++;

}

@Override
public void onResume() {
    super.onResume();
    activity.setPageTitle(headerPageTitle);
    setHasOptionsMenu(false);
    activity.getSupportActionBar().invalidateOptionsMenu();

}


public void isDialog(boolean b) {
    isDialog = b;
}

}
