【问题描述】：
我有一个控制 3 个片段的主 Activity。 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，它会在其中扩展自己的菜单。发生的情况是，MainActivity 和 Fragment 两个菜单的选项混合在一个选项菜单中。
截图如下：
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;
}
