menu.xml - (res -> menu)

<menu xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    tools:context=".HomeActivity">    <item        android:id="@+id/action_search"        android:icon="@android:drawable/ic_menu_search"        android:title="Search"        app:actionViewClass="android.support.v7.widget.SearchView"        app:showAsAction="always" /> </menu>

MainFragment.java

public class MainFragment extends Fragment {    private SearchView searchView = null;    private SearchView.OnQueryTextListener queryTextListener;    @Nullable    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {        return inflater.inflate(R.layout.fragment_main, container, false);    }    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setHasOptionsMenu(true);    }    @Override    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {        inflater.inflate(R.menu.menu, menu);        MenuItem searchItem = menu.findItem(R.id.action_search);        SearchManager searchManager = (SearchManager) getActivity().getSystemService(Context.SEARCH_SERVICE);        if (searchItem != null) {            searchView = (SearchView) searchItem.getActionView();        }        if (searchView != null) {            searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));            queryTextListener = new SearchView.OnQueryTextListener() {                @Override                public boolean onQueryTextChange(String newText) {                    Log.i("onQueryTextChange", newText);                    return true;                }                @Override                public boolean onQueryTextSubmit(String query) {                    Log.i("onQueryTextSubmit", query);                    return true;                }            };            searchView.setOnQueryTextListener(queryTextListener);        }        super.onCreateOptionsMenu(menu, inflater);    }    @Override    public boolean onOptionsItemSelected(MenuItem item) {        switch (item.getItemId()) {            case R.id.action_search:                // Not implemented here                return false;            default:                break;        }        searchView.setOnQueryTextListener(queryTextListener);        return super.onOptionsItemSelected(item);    } }

drawerLayout.setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS); 를 onCreate 안에 쓰고 

When use Action Bar, we usually init SearchView, menu item in onCreateOptionsMenu. That cause of SearchView search with old keyword. Solution is init SearchView, menu item in onPrepareOptionsMenu.

For an example:

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

   @Override    public void onPrepareOptionsMenu(Menu menu) {

// init menu item

 mMenuItemFilter = menu.findItem(R.id.action_filter);

       mMenuItemSearch = menu.findItem(R.id.action_search);        mSearchView = (SearchView) MenuItemCompat.getActionView(mMenuItemSearch);        mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {            @Override            public boolean onQueryTextSubmit(String s) {                search(s);                return false;            }

           @Override            public boolean onQueryTextChange(String s) {                search(s);                return true;            }        });

Following the best design principles for Android Apps can be quite tricky at times. Here I was trying to design a good search friendly app, and for some reason I just couldn't make it work as documented on the main site.
