How to add a Searchview to an Android Fragment?

Question

I created a Fragment and I’m trying to add a SearchView in that Fragment, but unsuccessfully, I haven’t found any consistent examples on the Internet and Google documentation provides only implementation of SearchView in Activities. Below is the code: Fragment:

public class BuscarFragment extends Fragment {

public BuscarFragment() {
    // Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.fragment_buscar , container, false);
}
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.campo_pesquisa, menu);

    SearchManager searchManager = (SearchManager)getContext().getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView =
            (SearchView) menu.findItem(R.id.barra_pesquisa).getActionView();
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));
}

}

campo_search.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/barra_pesquisa"
        app:actionViewClass="android.support.v7.widget.SearchView"
        android:title="Buscar"
        app:icon="@drawable/ic_search"
        app:showAsAction="ifRoom"
        />
</menu>

I have tried several solutions and have not succeeded in any. They could help?

I have a similar problem, and I was wondering if anyone could help me. I created the XML below and, as below, I put inside the Toolbar a Searchview. However I can’t instantiate it in the Fragment code.

 <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:layout_collapseMode="pin">

            <SearchView
                android:id="@+id/xProcurar"
                android:background="@color/branco"
                android:layout_width="match_parent"
                android:layout_height="40dp"
                android:elevation="5dp"
                android:fitsSystemWindows="true"
                android:layout_marginRight="10dp"
                android:layout_marginLeft="10dp"
                android:clickable="true"/>

        </android.support.v7.widget.Toolbar>

When I try to instantiate this Searchview, as below, I make Null Point error as if the object did not exist in the View (Fragment) :

SearchView sv = (SearchView) view.findViewById(R.id.xProcurar);

Below follows all Fragment XML

Someone could help me on how to instantiate and implement search action using this Searchview?

Thank you.

Answer 2

In Fragment

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.menu_tab1_fixo, menu);
    final MenuItem item = menu.findItem(R.id.search_fixo);
 }

The fixed.xml menu_tab1_from the Fragment menu

<?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/search_fixo"
    android:icon="@android:drawable/ic_menu_search"
    app:actionViewClass="android.support.v7.widget.SearchView"
    app:showAsAction="always|collapseActionView" />
</menu>

Answer 3

According to the documentation missed Return true; in the method onCreateOptionsMenu():

public boolean onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.campo_pesquisa, menu);

    SearchManager searchManager = (SearchManager)getContext().getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.barra_pesquisa).getActionView();
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));
    return true;
}
