Yes you can do it, you need to use ClickableSpan with SpannableString

paste this code inside your while loop

final String tag = matcher.group(0);
ClickableSpan clickableSpan = new ClickableSpan() {
                @Override
                public void onClick(View textView) {
                    Log.e("click","click " + tag);
                }
                @Override
                public void updateDrawState(TextPaint ds) {
                    super.updateDrawState(ds);

                }
            };
            hashText.setSpan(clickableSpan, matcher.start(), matcher.end(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

Dont forget to set setMovementMethod() on your TextView

holder.caption.setMovementMethod(LinkMovementMethod.getInstance());
