Android: Providing recent search suggestions without searchable activity?

I have an ActionBar SearchView and I am successfully able to make searches with it. The android documentation does not explain how to implement search suggestions. I do not want to have a searchable activity.

This is my search code:

public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_add_song, menu);
        final SearchView searchView = (SearchView) menu.findItem(R.id.song_search).getActionView();
        searchView.setFocusable(true);
        searchView.setIconified(false);
        final AddSongActivity activity = this;
        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextChange(String newText) {
                // Do nothing
                return true;
            }

            @Override
            public boolean onQueryTextSubmit(String query) {
                // Clear SearchView
                searchView.clearFocus();
                // Begin Spotify Search
                TextView notice = (TextView)findViewById(R.id.search_notice);
                URL url;
                try {
                    url = new URL("http://ws.spotify.com/search/1/track.json?q=" + URLEncoder.encode(query,"UTF-8"));
                } catch (MalformedURLException e) {
                    notice.setText("Malformed Search");
                    notice.setHeight(noticeHeight);
                    return true;
                } catch (UnsupportedEncodingException e) {
                    notice.setText("Unsupported Encoding. Maybe a problem with your device.");
                    notice.setHeight(noticeHeight);
                    return true;
                }
                new SearchDownload(url, activity).execute();
                notice.setText("Loading Tracks");
                notice.setHeight(noticeHeight);
                Log.i("infodb","" + noticeHeight);
                return true;
            }
        });

Ok, I spent my time for this. I make my own simple suggestion implementation from SQLiteDatabase.

We will create 3 classes like the following

MainActivity - for test of SearchView suggestion from database
SuggestionDatabase - this will store your recent search keyword.
SuggestionSimpleCursorAdapter - this is a subclass of SimpleCursorAdapter. I'll explain why I make this class instead of using SimpleCursorAdapter.

The codes

// MainActivity.java

public class MainActivity 
    extends Activity
    implements SearchView.OnQueryTextListener,
                SearchView.OnSuggestionListener
{

    private SuggestionsDatabase database;
    private SearchView searchView;

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


        database = new SuggestionsDatabase(this);
        searchView = (SearchView) findViewById(R.id.searchView1);
        searchView.setOnQueryTextListener(this); 
        searchView.setOnSuggestionListener(this);
    }

    @Override
    public boolean onSuggestionSelect(int position) {

        return false;
    }

    @Override
    public boolean onSuggestionClick(int position) {

        SQLiteCursor cursor = (SQLiteCursor) searchView.getSuggestionsAdapter().getItem(position);
        int indexColumnSuggestion = cursor.getColumnIndex( SuggestionsDatabase.FIELD_SUGGESTION);

        searchView.setQuery(cursor.getString(indexColumnSuggestion), false);

        return true;
    }

    @Override
    public boolean onQueryTextSubmit(String query) {
        long result = database.insertSuggestion(query);
        return result != -1;
    }

    @Override
    public boolean onQueryTextChange(String newText) {

        Cursor cursor = database.getSuggestions(newText)
