Android : SQLite snippet function implementation

I am building a search app and present the results in TextView inside a ListView. I want to bold the queried phrase/word in the search result. My SQLite select command is:

SELECT docid as _id, 
       COLUMN_1,
       COLUMN_2,
       COLUMN_3,
       COLUMN_4,
       snippet(FTS_VIRTUAL_TABLE)
       from FTS_VIRTUAL_TABLE
       where COLUMN_1 MATCH inputText;

Following is the String Array to be displayed in Separate TextView in ListView

String[] arr = new String[] 
                {
                    Html.fromHtml(COLUMN_1).toString(),
                    COLUMN_2,
                    COLUMN_3
                };

and my text views

int[] tViews = new int[] {     R.id.tv1,
                R.id.tv2,
                R.id.tv3}

And finally my cursor adapter

SimpleCursorAdapter myCursorAd = new SimpleCursorAdapter(this,R.layout.layout1, cursor, arr, tViews);
        mListView.setAdapter(myCursorAd);

I dont know what's wrong here. Its not working. It just displays the text as it is without any bold formatting.
