How to BOLD specific same text who fetching from database in android : I have a external database. I want to **BOLD** some specific texts. For example I have one column with **Word** name , and another column with **Example** . Each word have one example , in each example , use word. 

For example : word is **afraid** .

example is : The girl **afraid** of what she saw. 

I want when fetch data and show in recylerview , bold words inside example .

I use below code for reaching that, but doesn't work.


    String bolder = holder.title.getText().toString();

            SpannableStringBuilder stringBuilder = new SpannableStringBuilder(bolder);
            stringBuilder.setSpan(new android.text.style.StyleSpan(Typeface.BOLD), 0,
                    holder.title.getText().toString().length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            Log.d("span",holder.title.getText().toString());

            holder.example.setText(stringBuilder);
        holder.example.setText(wordsList.getExample());



I know , with html tag like <b></b> we can bolded , but my data is more , and I want use Spannable .
