        Spannable spannable = new SpannableString(text2);

        spannable.setSpan(new ImageSpan(mActivity, R.mipmap.start_quote_green), 0, 1, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
        spannable.setSpan(new ImageSpan(mActivity, R.mipmap.end_quote_green), text2.length()-1, text2.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
