		this.tv = (TextView)findViewById(R.id.text_view);
		
		CharSequence text = tv.getText();
		if (text instanceof Spannable) {
			int end = text.length();
			Spannable sp = (Spannable) tv.getText();
			URLSpan[] urls = sp.getSpans(0, end, URLSpan.class);
			SpannableStringBuilder style = new SpannableStringBuilder(text);
			style.clearSpans();// should clear old spans
			for (URLSpan url : urls) {
				MyURLSpan myURLSpan = new MyURLSpan(url.getURL());
				style.setSpan(myURLSpan, sp.getSpanStart(url), sp.getSpanEnd(url), Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
