SQLite 片段函数实现不会将 TextView 中的文本格式化为 HTML

我正在使用 SQLite 全文搜索实现搜索功能。我想像 Google 搜索一样用粗体查询文本显示结果！我已经实现了类似下面的代码，但它显示没有任何 HTML 格式的纯文本虽然将视图绑定到光标适配器并设置文本格式TextView。我无法弄清楚我的代码哪里错了？请任何帮助！

我在数据库适配器类中的搜索功能是：

public Cursor searchText(String inputText) throws SQLException 
{
    Log.w(TAG, inputText);
    String query = "SELECT "+
    "docid as _id," + 
    KEY_NAME + "," +
    KEY_INDEX + "," +
    KEY_TEXT_en + "," +
    KEY_TEXT_ur +  "," +
    KEY_TRANS_ur +  "," +
    "hex(matchinfo("+FTS_VIRTUAL_TABLE+")) AS "+KEY_OCCURRENCES+"," +
    "snippet("+FTS_VIRTUAL_TABLE+",'<b>','</b>')" +
    " from " + FTS_VIRTUAL_TABLE +
    " where ("+  FTS_VIRTUAL_TABLE +") MATCH '" + "\""+"*"+inputText+"\"*"+" ';";

    Log.w(TAG, query);
    Cursor mCursor = mDb.rawQuery(query,null);

    if (mCursor != null) 
    {

        mCursor.moveToFirst();
    }
    return mCursor;

}

我在活动类中向用户显示结果的显示结果函数是：

public void showResults(String query) 
{

    Cursor cursor = mDbHelper.searchText((query != null ? query.toString() : "@@@@"));

    if (cursor == null)
    {
    }
    else 
    {
        // Specify the columns we want to display in the result
        String[] from = new String[] 
                {
                    DbAdapter.KEY_TEXT_en,
                    DbAdapter.KEY_INDEX,
                    DbAdapter.KEY_NAME,
                };   
        // Specify the Corresponding layout elements where we want the columns to go
        int[] to = new int[] 
                {
                    R.id.TextEnTv,
                    R.id.IndexTv,
                    R.id.NameTv
                };
 final SimpleCursorAdapter cursorAdapter = new simpleCursorAdapter(this,R.layout.search_results, cursor, from, to);
        cursorAdapter.setViewBinder(new SimpleCursorAdapter.ViewBinder() {
            public boolean setViewValue(View view,Cursor cursor, int columnIndex) {
                   if (columnIndex == cursor.getColumnIndex(DbAdapter.KEY_TEXT_en)) {

                        TextView myView = (TextView) findViewById(R.id.TextEnTv);
                        myView.setText(Html.fromHtml(cursor.getString(cursor.getColumnIndex(DbAdapter.KEY_TEXT_en))));

                        return(true);
                      }

                      return(false);
                    }
                  });
        mListView.setAdapter(cursorAdapter);

文本视图显示未格式化的文本，因为代码告诉它显示 KEY_TEXT_en 列的内容，这是未格式化的文本。

要显示代码片段函数的结果，请为其命名：

SELECT ... snippet(...) AS snippet ...

并将该列用于文本视图。
