无法实现SearchView

Question

我不知道它是否与我的主题或任何应用程序设置有关，但我似乎无法实现SearchView，我不知道我做错了什么。我已经尝试了无数次，并将渲染与不同的API进行了比较，但我似乎无法让它工作：

menu_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"
xmlns:fanpolls="http://schemas.android.com/tools">
<item android:id="@+id/search"
    android:title="@string/hint_search"
    android:icon="@android:drawable/ic_menu_search"
    app:actionViewClass="android.support.v7.widget.SearchView"
    app:showAsAction="collapseActionView|ifRoom"
    />

新图片活动

public class NewImageActivity extends AppCompatActivity {

private SearchView mSearchView;
private RecyclerView mImageResults;
private RecyclerView.Adapter mImageResultsAdapter;
private ArrayList<Flicker> mPhotoArray;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_new_image);

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_search, menu);
    // Retrieve the SearchView and plug it into SearchManager
    MenuItem searchItem = menu.findItem(R.id.search);
    final SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
    searchItem.expandActionView();
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            return false;
        }

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