The following StackOveflow question seems to give a hint but I don't see how I can fit it into the current code: Highlight searched text in ListView items

1) Create global variable :

   private CharSequence search_txt = "";

2) Edit performFiltering method by adding the following right at the beginning :

  search_txt = constraint;

3) Finally, edit getView method by adding the following lines :

        holder.tvDuaName.setText(p.getTitle());
        //highlight(search_txt.toString(),holder.tvDuaName.getText().toString());
        String filter = search_txt.toString();
        String itemValue = holder.tvDuaName.getText().toString();

        int startPos = itemValue.toLowerCase(Locale.US).indexOf(filter.toLowerCase(Locale.US));
        int endPos = startPos + filter.length();

        if (startPos != -1) // This should always be true, just a sanity check
        {
            Spannable spannable = new SpannableString(itemValue);
            ColorStateList blueColor = new ColorStateList(new int[][] { new int[] {}}, new int[] {        Color.BLUE });
            TextAppearanceSpan highlightSpan = new TextAppearanceSpan(null, Typeface.BOLD, -1, blueColor, null);

            spannable.setSpan(highlightSpan, startPos, endPos,    Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            holder.tvDuaName.setText(spannable);
        }
        else
            holder.tvDuaName.setText(itemValue);

P.S : There is one correction. In the if else statement right after the line :

            ViewHolder holder;

After you have completed the "if" part, you forgot to add the "else" and have begun without it. Add the "else" otherwise the logic is wrong.

UPDATE Issue has been re-opened. Future iterations should work for recyclerView.
