我希望在更改活动中的片段时更改片段活动(abs)的菜单项的可见性.片段是SherlockListFragments.

我要显示/隐藏的菜单项是我在菜单创建时创建的微调器:

public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    MenuInflater inflater = getSupportMenuInflater();

    IcsSpinner herbSortSpinner = new IcsSpinner(this, null, R.attr.actionDropDownStyle);
    SpinnerAdapter herbSortSpinnerAdapter = ArrayAdapter.createFromResource(this, R.array.herb_sort_elements, android.R.layout.simple_spinner_dropdown_item);
    herbSortSpinner.setAdapter(herbSortSpinnerAdapter);
    herbSortSpinner.setOnItemSelectedListener(this);
    herbSortSpinner.setId(HERB_SPINNER_ID);
    menu.add(R.string.menu_sort).setActionView(herbSortSpinner).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);

    IcsSpinner noteSortSpinner = new IcsSpinner(this,  null, R.attr.actionDropDownStyle);
    SpinnerAdapter noteSortSpinnerAdapter = ArrayAdapter.createFromResource(this, R.array.note_sort_elements, android.R.layout.simple_spinner_dropdown_item);
    noteSortSpinner.setAdapter(noteSortSpinnerAdapter);
    noteSortSpinner.setOnItemSelectedListener(this);
    noteSortSpinner.setId(NOTE_SPINNER_ID);
    menu.add(R.string.menu_sort).setActionView(noteSortSpinner).setVisible(false).setEnabled(false).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);

    inflater.inflate(R.menu.activity_lexicon, menu);
    menuHolder.setMenu(menu);
    return true;
}

我切换片段的逻辑是:

public boolean onNavigationItemSelected(int position, long itemId) {

    FragmentManager fragmentManager = getSupportFragmentManager();
    FragmentTransaction fragmentTransaction …
