Lets not use SearchView directly, in your menu.xml

<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>

and add this simple code to your java :

@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);
}

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

onCreateOptionMenu method

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.search_view_menu_item, menu);
    MenuItem searchViewItem = menu.findItem(R.id.action_search);
    final SearchView searchViewAndroidActionBar = (SearchView) MenuItemCompat.getActionView(searchViewItem);
    searchViewAndroidActionBar.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            searchViewAndroidActionBar.clearFocus();
            return true;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            return false;
        }
    });
    return super.onCreateOptionsMenu(menu);
}
