is it possible to find a #hashtag and an "http://" link from a string and color it ? I am using this in Android.

public void setTitle(String title) {
    this.title = title;
}

Thanks in Advance

I have found an answer and here is the way to do it :

        SpannableString hashtagintitle = new SpannableString(imageAndTexts1.get(position).getTitle());
        Matcher matcher = Pattern.compile("#([A-Za-z0-9_-]+)").matcher(hashtagintitle);
        while (matcher.find())
        {
            hashtagintitle.setSpan(new ForegroundColorSpan(Color.BLUE), matcher.start(), matcher.end(), 0);

        }
        textView.setText(hashtagintitle);
