我想知道如何仅在父片段中的操作栏中显示searchview。现在,当我从动作栏中的searchview提交搜索并转到下一个片段时,我仍然可以在我的子片段中看到searchview。有什么建议可以解决吗?感谢。

现在,在我的父类

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setHasOptionsMenu(true);
}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {

    // Inflate the options menu from XML
    inflater.inflate(R.menu.homesearchbar, menu);
    super.onCreateOptionsMenu(menu,inflater);

    // Get the SearchView and set the searchable configuration
    SearchManager searchManager = (SearchManager) getActivity().getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
    searchView.setMaxWidth(Integer.MAX_VALUE);
    searchView.setIconifiedByDefault(false); // Do not iconify the widget; expand it by default
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            Bundle bundle = new Bundle();
            bundle.putString("HomeToSearch_keyword", query);
            SearchVC searchVC = new SearchVC();
            searchVC.setArguments(bundle);
            getFragmentManager().beginTransaction().add(R.id.HomeVC_frameChildFragment, searchVC)
                    .addToBackStack(null)
                    .commit();
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            return false;
        }
    });
}

homesearchbar.xml

<?xml version="1.0" encoding="utf-8"?>
<menu
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/action_search"
        android:title=""
        app:actionViewClass="android.support.v7.widget.SearchView"
        app:showAsAction="always"/>
</menu>

隐藏searchView内的子片段override内的onPrepareOptionsMenu方法。然后在该方法中,您可以执行以下操作:menu.findItem(R.id.search).setVisible(false);或最终在需要时将其更改为true。另外,请不要忘记override onCreate方法放置setHasOptionsMenu(true);
