This Android Java Program demonstrates hyperlinks within Text View using Linkify class in Andorid.

Here is source code of the Program demonstrates a Simple Compound Control. The program is successfully compiled and run on a Windows system using Eclipse Ide. The program output is also shown below.

Linkify is a helper class that creates hyperlinks within Text View (and Text View-derived) classes through RegEx(or Regular Expressions)pattern matching.
Text that matches a specified RegEx pattern will be converted into a clickable hyperlink that implicitly fires startActivity(new Intent(Intent.ACTION_VIEW, uri)),using the matched text as the target URI.
