如何从Fragment菜单选项中分离MainActivity菜单选项？

标签： android android-fragments

我有一个主要活动来控制3个碎片。 MainActivity在选项菜单上有一个搜索栏和一些过滤器。问题是其中一个片段（ResultadosFragment）有自己的OnCreateOptionsMenu（）实现，它会扩展自己的菜单。会发生什么 - 两个选项 - MainActivity和Fragment - 菜单只在一个选项菜单中混合在一起。

这是一个截图：

enter image description here

MainActivity - OnCreateOptionsMenu（） 

@Override
public boolean onCreateOptionsMenu(final Menu menu) {
    super.onCreateOptionsMenu(menu);

    mOptionsMenu = menu;
    //Carrega o arquivo de menu.
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_search_bar, menu);

    menu.findItem(R.id.usado).setChecked(true);
    menu.findItem(R.id.longplay).setChecked(true);
    menu.findItem(R.id.nacional).setChecked(true);

    //Pega o Componente.
    final SearchView mSearchView = (SearchView) menu.findItem(R.id.search)
            .getActionView();
    //Define um texto de ajuda:
    mSearchView.setQueryHint("Banda - Álbum");

    // exemplos de utilização:
    mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            searchQueryGlobal = query;
            realizarPesquisa();

            mSearchView.setIconified(true);
            mSearchView.clearFocus();
            // call your request, do some stuff..

            // collapse the action view
            if (menu != null) {
                (menu.findItem(R.id.search)).collapseActionView();
            }
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            Log.i("well", " this worked");
            return false;
        }
    });

    return true;
}

ResultadosFragment - OnCrateOptionsMenu（）AND onOptionsItemSelected（） 

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    // Inflate the menu; this adds items to the action bar if it is present.
    inflater.inflate(R.menu.menu_resultados, menu);
    super.onCreateOptionsMenu(menu, inflater);
    mOptionsMenu = menu;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle item selection
    switch (item.getItemId()) {
        case R.id.menuRemoveLowReputation:
            exibirMensagemReputacaoMaxima();
            return true;

您可以在menu.clear()

中撰写OnCreateOptionsMenu() 
 @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        menu.clear();
        inflater.inflate(R.menu.menu, menu);
    }

我不知道这是不是最好的做法。如果有人知道告诉我们。 =）
