Example: Suppose you have set some text in textview and you want to provide a link on a particular text expression: "Click on #facebook will take you to facebook.com"

In layout xml:

In Activity:

String text  =  "Click on #facebook will take you to facebook.com";
tv.setText(text);
Pattern tagMatcher = Pattern.compile("[#]+[A-Za-z0-9-_]+\\b");
String newActivityURL = "content://ankit.testactivity/";
Linkify.addLinks(tv, tagMatcher, newActivityURL);

Also create one tag provider as:

public class TagProvider extends ContentProvider {

    @Override
    public int delete(Uri arg0, String arg1, String[] arg2) {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public String getType(Uri arg0) {
        return "vnd.android.cursor.item/vnd.cc.tag";
    }

    @Override
    public Uri insert(Uri arg0, ContentValues arg1) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public boolean onCreate() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public Cursor query(Uri arg0, String[] arg1, String arg2, String[] arg3,
                        String arg4) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public int update(Uri arg0, ContentValues arg1, String arg2, String[] arg3) {
        // TODO Auto-generated method stub
        return 0;
    }

}

In manifest file make as entry for provider and test activity as:

Now when you click on #facebook, it will invoke testactivtiy. And in test activity you can get the data as:

Uri uri = getIntent().getData();
