Twitter link android all @mentions

I want to link to all twitter @mentions in mytweets app in android. If I click on @mentions, I want to open another page about @mentions.

This code doesn't work. First, I want to search for @mentions on twitter, and I link to this @mentions, and if I click this @mentions on tweet, I want to open another page about this @mentions.

TextView bt = (TextView) v.findViewById(R.id.bottomtext);
Pattern atMentionPattern = Pattern.compile("@([A-Za-z0-9_]+)");
String atMentionScheme = "http://twitter.com/";

TransformFilter transformFilter = new TransformFilter() {

    public String transformUrl(final Matcher match, String url) {
        return match.group(1);
    }
};

Linkify.addLinks(bt, Linkify.ALL);
Linkify.addLinks(bt, atMentionPattern, atMentionScheme, null, transformFilter);
