Highlight a particular word in a String dynamically

Question

I want to highlight a particular word in a text view ( more specifically similar to a twitter feed). The word may occur multiple times. Below I will post a sample sentence from twitter.

" Mumbai Master Blaster! #Sachin. Greatest players of all times. The legend of cricket #sachin. "

Here I want to highlight the word " #Sachin " with a particular color. Also please note that we don't know how many times this word could get repeated in the whole string. Could anyone help me to solve this issue.

Use next code:

public CharSequence linkifyHashtags(String text) {
    SpannableStringBuilder linkifiedText = new SpannableStringBuilder(text);
    Pattern pattern = Pattern.compile("@\\w");
    Matcher matcher = pattern.matcher(text);
    while (matcher.find()) {
        int start = matcher.start();
        int end = matcher.end();
        String hashtag = text.substring(start, end);
        ForegroundColorSpan span = new ForegroundColorSpan(Color.BLUE);
        linkifiedText.setSpan(span, 0, hashtag.length(), 0);
    }
    return linkifiedText;
}
