検索フィルターで検索したテキストを強調表示するにはどうすればよいですか？

すべての「表示されている」検索文字が強調表示されるように検索しようとしています。私はスパナブルを使ってみましたが、それはうまくいきませんでした、多分私はそれを正しくしていませんでしたか？これに基づく：ListViewアイテムで検索されたテキストを強調表示する表示されているテキストを強調表示するにはどうすればよいですか？これが私のフィルターです：

private LayoutInflater mInflater;

        private ValueFilter valueFilter;

        public MySimpleArrayAdapter(Activity context) {

            this.context = context;
            mInflater = LayoutInflater.from(context);

        }
        private class ValueFilter extends Filter {

                            if(filterList.contains(i))
                                continue;

                            filterList.add(i);

                        }

                    results.count = filterList.size();

                    results.values = filterList;
